    Lowes did not have the left handed threads.

  • Anonymous Apr 21, 2009

    I have the same problem with my thermocouple and Lowe''s does not have the art needed to convert the left handed thermocouple. I have own this water heater for only 5 years and now I probably need to purchase a new one unless someone can tell me where to get this part. IN SEROUS NEED!!!!!!

With a fine tooth hacksaw cut a slot in the old nut so it can be removed from the old 1/8 inch cu tubing. Now place the old nut around the new tubing and thread it into the gas valve

They make a adapter you can buy at lowes to switch the thread pattern for thermocouples. If you can't find it post me back and I will try to find another location you can get it at.

You can buy the control valve assy (right next to the thermocoupler on the shelf at lowes) its about $54. It has the correct threads for the new thermocoupler threads An adapter will not work because the thermocoupler will not be able to close the switch to keep the pilot on if you extend the distance between the coupler fitting and the controller. I had the same problem when my thermocoupler died again and they stopped selling the whirpool brand coupler.

I had the same problem. My local Lowes store carries the converter kits (to change from left-hand thread to right-hand thread on the thermocouple) free of charge. However, my Lowes was out of stock on them and directed me to contact Whirlpool. Whirlpool has the kits also at no charge, but you do have to pay for shipping and handling.

Scottsz is correct, but they will ship you the entire housing and a converter (still free of charge) and they no longer charge shipping and handling if it is still in warranty.

I'll add that i was able to get a payment authorization number from Whirlpuddle (877-817-6750) to allow me to go to my local Lowes and pick up the part. Less simple that it sounds. Eight calls to Cesspool and three trips to Lowes ...and then the four trips to hardware stores before i was convinced the left hand thermocouple no longer exists. Holiday weekend, would have been 5 days to get to me from Whizpool.
FYI-Whirlpool called it a conversion kit, The Whirlpool box at Lowes was marked enhancment kit. $35 if you need to by it. A bargan. If only I had known at the beginning.

    Guy, my thermocouple went out this weekend. I called Lowes since that is where I purchased my hot water heater. The assure me they had the part. Except, once I got the part home and tried to use it, I found I needed a "left hand thread" piece.

Flame of water heater does not light up


You need to replace you thermocouple its the tiny copper in color probe going into water heater. This componet works of milli volts and keeps the pilot lit when this goes bad the pilot goes out. Heres what you need to do shut gas off take all fittings off gas valve thats the thing with the knob on it to set water temp. pull out manifold and remove thermocouple by pulling at the base straight out. You can buy replacement thermocouples at your nearest hardware store.

We replace the thermocouple and cant get the pilot t stay lte.its on a 40 gal hot water heater


Sometimes, when DIYers install a new thermocouple they over tighten it. The correct way to install a thermocouple is to finger tighten the connection into the gas control valve and then, with appropriately sized open in wrench, tighten it only 1/4 turn more. Over tightening it, can cause the control valve to lockup. Also, check the positioning of the thermocouple. The pilot flame should engulf the tip of the thermocouple. If it doesn't reposition the thermocouple and clean the pilot. Especially clean it, if the pilot flame is curling upward, instead of being straight out.

Hope this helped you troubleshoot and solve the problem.

I have a Whirlpool gas hot water heater. The pilot light will not stay lit: it ignites but as soon as I release the RESET button, the pilot goes out.


change your thermocouple. You can get one at any hardware store. the thermocouple is the small rod looking device next to the flame of the pilot light. It has a copper looking line about as round as a pencil lead that connects to the gas valve. Disconnect the line from the thermocouple from the gas valve and you may be able to just pull it out from the pilot assembly. take the old one in to the hardware store so you'll get the right length.

I replaced the gasvalve and thermalpile in my 35,BTU wall heater I light the pilot and turn the heat on it goes out I ran a new state wire in case of a short but it still does it, did I get a bad...


Did you get the right gas valve for a thermapile and not a 24 volt gas valve? Also I would recheck my wiring.... Here is a article that may be of HELP....... Hope this Helps.....
Thermocouple: A thermocouple is a device made of two different metals which creates a small electrical charge when heated at one end.
Thermopile: A thermopile is a probe that contains multiple thermocouples, therefore it can produce a larger electrical current. Millivolts: 1/1000 of a volt - thermocouples and thermopiles typically produce from 25 to 600 millivolts of power.
Piezio - a spark producing device often used to ignite gas pilots and burners.
Gas Valves Types:
A. Single Thermocouple Only - Used on some gas logs
B. Valves with Thermocouples and Thermopiles - Used on most hearth appliances and gas logs with switches or remote controls or thermostats.
C. ODS Systems - Used on Mostly Vent-Free. Available in manual control or thermostat/remote/switch (combination) valves.
valvepict.jpg
Typical Gas Valve A. Thermocouple-Only
Found in: Most gas log sets with standard safety pilot knob control. Also found in certain gas space heaters and construction-site portable heaters.
Explanation: This type of gas valve used a single thermocouple. A thermocouple is a device made of two different metals which creates a small electrical charge when heated at one end by the gas pilot. This small charge causes an electromagnet inside the gas valve to open and allow gas to flow to the main burners. Since the thermocouple must be heated before the burner will start, gas appliances often have a startup mode, during which a knob must be depressed and held for 30 seconds or so after lighting the pilot. At the end of the 30 seconds, the pilot should be generating enough electricity for the valve to operate correctly. At this time, the startup knob can be released and the valve turned to an "on" position for appliance operation.
pilotclose.gif Troubleshooting:
Most problems with this type of valve are due to thermocouple problems. Check the following:
1. Connection from the thermocouple to the valve. Clean the threads of the connecting nut with a pencil eraser and re-tighten.
2. Pilot hood and flame direction. The pilot should engulf the top 5/8" of the thermocouple with a decent flame. If the flame hits the thermocouple too low, this can cause the appliance to go out or not generate enough millivolts for valve operation. The pilot hood and orifice should also be clean from soot which could slow or block the pilot flame.
3. Pilot pressure. Many of these valves have an adjustment screw to adjust the pilot flame. A pilot that is too short may allow the pilot to stay lit after ignition, but may not create enough charge to allow the burners to ignite.
4. Overheating: If the unit works for a few hours and then shuts down, it's possible the thermocouple has become overheated. Repositioning of the gas valve and/or pilot may be needed to avoid this problem.
Problems with LP units can also be due to a tank that is nearly empty or a bad regulator at the tank.
B. Thermocouple & Thermopile valve
gas1.gif Found in: Most modern VENTED gas stoves, fireplaces and fireplace inserts as well as vented gas log sets with thermostat or remote control.
This valve is similar to the thermocouple only valve, however has a pilot which heats up BOTH a thermocouple and a thermopile. The thermocouple still acts to prove that the pilot flame is on and allows this flame to continue after startup. The thermopile is used to power a second circuit which is used to open the main valve. This second circuit is powerful enough (300-600 millivolts) to allow the use of a thermostat, wall switch or control switch to operate the main valve. Control of the valve is obtained simply by hooking a pair of wires to two terminals located on the valve.
Startup is similar to the thermocouple-only valve. A piezo spark ignition is used to ignite the pilot after the gas knob is turned to the "pilot" position and depressed. Once the pilot is lit, the knob is held in for 30 seconds to "prove" the heat and then released and turned from the "pilot" to the "on" position. The main burner will then respond to the switch, thermostat or remote control.
Troubleshooting
Since there is both a thermocouple and thermopile in this valve type, it is important to isolate where the potential problem may be. If the pilot can be lit and stays on after the knob is released, then the problem is probably with the thermopile side of the valve. Here are the most common problems and solutions.
1. Pilot does not light or stay lit after knob is released - Make certain that the Piezo igniter works by checking for a spark between the igniter tip and the pilot hood. If there is no spark, the piezo may be bad or the piezo wire might be shorting to the appliance chassis. It is also possible that the igniter tip needs to be bent slightly toward the pilot hood so the spark jumps to it.
Check carefully that gas to appliance is on and that the valve is in he correct (pilot) position and fully depressed when lighting.
If pilot ignites but does not stay lit after knob is released, then the problem is with the thermocouple not generating enough voltage to the valve. It may be that the pilot adjustment needs to be turned up, or the thermocouple replaced. Another possibility is that the thermocouple may not be being "bathed" fully by the pilot flame. Check your owners manual for a diagram and description of the proper pilot flame and hood adjustment. It is also possible that there is soot or other blockage in the pilot tube, orifice or hood which is reducing the size of the pilot (and also the voltage of the thermocouple).
2. Pilot stays lit, but appliance will not turn on - There are two common causes for this. It is possible that the thermopile is not producing enough millivolts to power the control circuit. The millivolts can be checked with a simple voltmeter (consult the owners manual for proper setting) and adjusted with the pilot adjustment screw. Improper millivolts will also cause the appliance to shut down in the middle of operation.
Another common problem is loose or poor connections or circuits to your appliance switch, thermostat or remote transceiver. This can be isolated by simply using a small piece of wire to jump the "TP" and "TH" terminals located on these valves. If the appliance turns on when these terminals are jumped, then you can be sure that your problem is not in the appliance itself, but further down the switch circuit. Make certain you have used the suggested gauge of wire and that the length for your control runs does not exceed the specs given in your manual.
3. Other possible problems - include wind or back drafts affecting the pilot flame and checking of "spillage" circuits which may be wired into the valve in most B-Vent units.
If all the above checks out, and your valve is still acting weird (i.e., works some of the time), then you may have a defective gas valve in the appliance. Problems with LP units can also be due to a tank that is nearly empty or a bad regulator at the tank.
C. ODS System
Found in: Unvented (Ventless, Vent free) gas logs, fireplaces and stoves. These systems are available in manual or remote control.
ods.gif ODS stands for "Oxygen Depletion Sensor" , a term which accurately describes this valve type. The valve itself is similar in many ways to the two valve types above...with one exception. The pilot tube is a precision mechanism that creates a very stable flame as long as the room air contains the proper amount of oxygen. If the oxygen level in the room air drops even slightly, the pilot becomes unstable and lifts off of the thermocouple (see diagram) causing the gas valve and appliance to cease operation. This type of valve is very reliable, and there have been very few failures of this system - even with tens of millions in use worldwide.

I WOULD LIKE TO REPLACE MY THERMO CUPPLING


In simplest terms, a thermocouple is a temperature sensor. Normally inexpensive, a thermocouple is standard on hot water tanks. If your thermocouple breaks or you feel it is not working properly, consider replacing it b?p=y23r90wnbq7oglkvtnbuhgyhrktxauzqpeoaddsf&t=18g7grtjm%2fx%3d1290445898%2fe%3d2143440281%2fr%3dacont%2fk%3d5%2fv%3d8.1%2fw%3d0%2fy%3dyahoo%2ff%3d2680761980%2fh%3dcg49imfjb250iibzzxj2zulkpsjzmjnsotb3tkjxn09nbgtwve5ivuhnewhys1r4yvv6cxbfb0fezfngiibzaxrlswq9ijq4mtmwnteiihrtdg1wpsixmjkwndq1odk4ota5njiwiia-%2fq%3d-1%2fs%3d1%2fj%3d6f060d4c&u=13gohjn6b%2fn%3df8a.bkwnpkw-%2fc%3d715481.14405591.14260180.13829426%2fd%3dlrec%2fb%3d6235626%2fv%3d1 lg.php?category_id=6&content_type=article&content_type_id=584031&key_page=1721642411054458764&site_id=1&bannerid=10089&campaignid=2945&zoneid=2&loc=1&referer=http%3a%2f%2fwww.associatedcontent.com%2farticle%2f584031%2fhow_to_change_a_thermocouple_on_your.html%3fcontent_type_id%3d584031&cb=ebe6534afeavw.php?zoneid=2&cb=1721642411054458764&source=&n=a14de4a9&slice=-1060-&dma=-0-&cty=-us-&content_type=article&content_type_id=584031&category_id=6&key_ad=1045292919&site_id=1&ad_pos=2&key_page=1721642411054458764&ac_url=http%3a%2f%2fwww.associatedcontent.com%2farticle%2f584031%2fhow_to_change_a_thermocouple_on_your.html rather than installing a new gas hot water heater.

Begin this project by shutting off the gas control knob on your hot water heater. Once you are sure that the gas is off, you should use a wrench to remove the nut that attaches the thermocouple to the gas hot water tank. This nut should appear to be securing a piece of copper tubing or other type of tubing. With the nut removed, you should also pull down on the tubing, dislodging it from the thermocouple.

Sometimes there is another nut that attaches the end of the thermocouple to the pilot bracket, if this is the case you should unscrew this nut as well. You can slide it down the tubing and keep it there until you need to replace it.

With the nuts that were holding the unit in place removed, you should be able to slide the old thermocouple out of the brackets that hold it to the hot water heater. You should then take it to a hardware or home improvement store and find a suitable replacement. Then follow these steps to install the new part and fix the hot water heater.

To change the thermocouple, you should press the end of the thermocouple into the pilot bracket as far as you can. If you had to remove a second nut to remove the old thermocouple, now is the time to replace that nut securely.

With the thermocouple in place, you should connect the lead to the control unit. Use the nut you removed in the beginning steps to secure the lead. You should then tighten it at least a quarter turn with a wench to make sure the lead is securely attached to the control unit of the gas hot water heater.

Now that the new thermocouple is installed on your gas hot water heater, turn on the gas shut off valve that you turned off earlier. You should be able to relight the pilot and the functionality of your gas hot water heater should be restored.

Try to ignite pilot on 15/30b. flame ignites but goes out immediately when i realease the green button after 20 seconds. have replaced thermocouple but still no joy - any ideas ?


First, I'm assuming you have a residential Gas-Fired Heater or Water Heater that you are having problems with. My answer is based on this assumption.

Most thermocouples require that you hold the button for at least 45 seconds. Try holding the button for 60 seconds prior to releasing it. If this does not work, you can test your new thermocouple if you have a multimeter...preferably one with an alligator clip for your leads. To test your thermocouple, disconnect the end that screws into your gas valve. Set your multimeter to read Milivolts. Put your red lead on the copper line of the thermocouple.....it's easier if you have an alligator clip. With your pilot lit, hold down the button for 45 seconds and continue to hold while you put the black lead of your tester on the very end of the thermocouple (the part that attaches to the gas valve). You should read a minimum of 12 milivolts. If you do not read 12 milivolts, your new thermocouple is bad. If you are reading 12 milivolts, screw it back into the gas valve, relight, hold the button for minimum 45 seconds. Release the button. If the pilot goes out immediately, the problem (>99% probability) is with your gas valve.

We have a whirlpool hotwater heater model #fg1404t3nv and we can not get the pilot light to stay lit. help please we need hot water and do not have the money to replace it


Fear not, unless you havewater leaking from the tank you won't have to worry with replacing it.

Heres how your heaters ignition system works.

The Pilot is lit, and the flame sensor detects flame and sends signal to the gas valve.The gas valve then sends gas to the burners and the burnes ignite.

If the gas valve does not recieve signal from the sensor it will not come on and it will shut off all gas to the pilot, and burners to prevent raw gas from dumping into your home.

If your system has a thermocouple, 99% change the problem is the thermocouple.

When I service a customers unit, I automatically replace the thermocouple because they are so notoirus for going bad.

You can buy one at Lowes for less than 10 bucks.

To locate the thermocouple, go to the gas valve, fint the small copper tube (about as thick as a pencil lead) and follow it to the pilot. The sensor will be slightly larger in diameter and about 2 to 3 inches long.

You can try cleaning the sensor with steel wool, but usully they just need to be replaced.

To replace it, turn off the gas, unscrew the nut holding the tube in the gas valve, and disconnect the sensor from the ignitor/pilot assembly. Make sure your new T-couple is long enough, as the come in different lengths, you can simply coil the extra length up out of the way near the gas valve.

Install the new one as you removed the old one.

Relight pilot, be sure to hold the button down long enough, and enjoy your hot shower!

If you have any other problems, let me know, and I will be glad to help you.

I have a kenmore power miser 8 water heater no hot water even though i am a girl i worked in a hardware store for 8 yrs so i opened spot to top element and pushed reset button. it worked for a day. today...


The good news is this is a fairly common problem. Generally when a water heater pilot light goes out it is due to a faulty thermocouple. Replacing this is simple, takes just a few minutes and the part can be found at almost any hardware store.

Now for the not so good news. Kenmore and Whirlpool water heaters are both made by the same company and have severe problems with the gas control/thermostat unit. There is an internal sensor for the thermocouple inside and this goes bad. You can buy the unit and install it or have it installed by a plumber or Sears. Call the service number on the side of the water heater. If you change the unit yourself, there are instructions in the package the unit is in and instructions can be found online. Make sure you turn off the gas line running to the waterheater and release some water pressure from the water heater before you start. It is fairly easy to replace.
