Pilot has been going out on its own


You most likely have a bad thermocouple that needs to be replaced, but other causes can be a blocked flue, sooted-up burner chamber, strong down draft from wind blowing out your pilot from improper venting or high temp switch is bad or needs to be reset. Need more info on your type of heater to diagnose it. Check the pilot flame when lit and see if it is heating the thermocouple and making it red hot. It should be a nice firm blue pilot flame. Lazy yellow pilot flames may not be heating the thermocouple enough or has caused the thermocouple tip to be burnt off and is now failing to keep the pilot lit.

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.

What could be wrong with ruud farnace 80% when the burners slow down and start making noise like is not gas pression and the pilot shut off.


I would first concentrate on the pilot flame, and thermocouple. Make sure pilot flame is good and strong , and thermocouple end above flame is cleaned well. If flame appears proper, sometimes a good rub down on thermocouple end with fine steel wool will do the trick. The thermocouple senses the heat from the pilot and thus signals gas valve that it's ok to send gas for operation. If debris collects on that thermocouple and it doesn't sense proper heat from pilot flame, it will not signal gas valve to open.

Why does pilot light turns on gas burner only to have it go out about 10 seconds later? 30 to 40 sec later repeats,without lighting. What is problem? once in awhile, it will light..not often. The burner...


Hello
Sounds like the thermocouple is going bad.The thermocouple is a thin tube that runs from the pilot lite to the gas valve.
What it does is it sences the heat from the pilot lite and keeps the gas valve open to allow the pilot to stay on.
This can be easily repaird by shutting off power and gas to your heater and removeing the thermocouple from the gas valve,then unclip or unscrew it from the pilot lite area.
Any plumbing supply store or home depot or lowes should have these.

Once you get a new one,install to gas valve and pilot lite area then turn on power and gas to heater and follow pilot lighting procedure,you may need to hold gas on for 60 seconds.

Here is a picture of the thermocouple so you know what to look for.

Pilot hard to lite when lites stays on about 15 minutes goes out this is on reliance gas hot water heater 101


The thermocouple has gone bad or in this case is going bad to the point that it is useless.

The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to ignite natural gas or propane fuel to the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close. Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners. Neat huh?

Pilot LIGHT KEEPS GOING OUT OUT


The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

My pilot light keeps going out on my comfort glow infrared propane heater what could be making it go out?


The thermocoupler is faulty. It is that bulb that sits i the pilot flame. It controls the gas valve so you won't get any gas if the pilot goes out.. So, the thermocoupler needs to be replaced. Inexpensive and easy fix. Good Luck _Ned_

Kenmore gas oven model no. 273 3248296 pilot free ignition wont fire up


Hi

If it won’t fire then it is possible that the oven control is not sending gas for the pilot light. The pilot light works but no main burner ignition - possible pilot assembly is dirty and the pilot flame is too small, safety valve and thermocouple is faulty, the bulb from the safety valve is out of position and the pilot flame is not touching the thermocouple bulb. Some ranges use a standing pilot light ( small flame is on all the time ) while others use an spark ignition to light the pilot light flame and the pilot light flame heats up the thermocouple bulb to allow the main gas to flow through the oven burner.
The flame needs to heat the bulb up enough to tell it to open the gas valve. Several things can go wrong here that keep this from happening:
The pilot flame may not be hot enough, usually because the flame is yellow instead of pure blue or is too small. The cause for this is usually a dirty pilot assembly. The pilot assembly would either need to be cleaned or replaced.
The thermocouple bulb may not be positioned properly in the flame. You can't heat the bulb properly if it's not in the pilot flame! The thermocouple bulb needs to be in the upper third of a pure blue pilot flame--that's the hottest part of the flame.
The thermocouple itself may be burned out. It happens. It's an internal part of the gas valve so, no, you can't just change the thermocouple bulb separate from the gas valve.
But when you turn on the oven or the thermostat calls for heat, the pilot flame gets bigger and jumps down so it can heat up the thermocouple bulb. This extra gas to increase the pilot flame size comes from the thermostat.
If the pilot flame jumps upwards or just gets bigger, but doesn't shoot down, then you need to replace the pilot assembly.
If the pilot flame size does not increase or jump down when turning on the oven thermostat, then the problem is the thermostat not sending enough gas to the pilot assembly. It's also possible that the pilot gas supply tube has a hole in it somewhere.
One final point on the spark-assisted pilot ignition systems. The spark comes from the spark module--the same module that sends spark to your surface burners to light them up. If you're not getting a spark when you turn the oven on, then there are several possibilities:
There could be a problem with the switch in the thermostat. You can confirm this by doing a simple continuity test of the thermostat contacts. If you don't read zero ohms when you turn the switch on, replace the thermostat.
The spark module could be bad. You'll need to measure the voltage at the oven terminals of the spark module when you turn on the oven. If you get 120v but no spark, it's probably a bad spark module. Replace it.
Could be a bad spark wire or broken electrode.

Please do rate the solution and revert for further assistance.


Thanks

Propane patio heater ignition problem


I would change the thermocouple and here is why:

The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.

Heater kicks on, but kicks right off


There is a small probe that is heated by the pilot flame. This is called a thermocouple & keeps the gas valve open by generating a small electric current. Most likely the pilot flame is too small, or not heating the thermocouple properly. Either turn the pilot up a bit, or gently bent the thermocouple bracket to put it in the flame a bit more. Do not try to bend the thermocouple itself. If this does not help, a new thermocouple may be needed.
