SOURCE: pilot light will not stay lit

Clean the pliot light tube with a Q-Tip and alcohol. Clean 2 inches deep. This will increase the pilot light flame and it will heat up the thermocoupler so it will stay lit.

SOURCE: Laars Lite 2 LG - pilot light will not stay lit.

It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.

THE flame from the pilot should shoot past the thermo-couple and heat this up and make a small amount of mili- amps to prove the pilot light is lit. ..So if the flame doesn,t go past the thermo-couple it won, make mili-amps or its tme to change out the thermo-couple, They only cost lest than $8:00 and you can change it!

SOURCE: pilot light flame is mostly yellow. LP gas

Hi,
Thr thing you need to do is take the pilot assembly all apart and blow the dust and dirt out of it.
After burning for many, many hours the air that is move up through the pilot assembly leaves dust and dirt which plugs off a bit of the air and makes the flame run rich. Meaning that it does not get enough air mixed in for complete combustion.
When you clean it you will see the dirt and dust com out of it.
Reassemble carefully just as you took it apart and it will be back to working great again!!

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Hi and welcome to FixYa, I am Kelly.

What you are experiencing is the lack of a signal from the thermocouple to the gas valve. I.e. the thermocouple is not passing heat information at all. This is caused by either a defective thermocouple, a dirty mating area where the thermocouple connects to the gas valve or... an improperly positioned thermocouple that is not "in the flame" with the pilot lit.

  • First make sure the FIRE end of the thermocouple is in the flame when lit. (reposition if necessay)
  • Next disconnect the thermocouple by unscrewing the fitting on the top of the gas valve. (No gas will come out) Clean the metal mating area as best you can and then re-install the thermocouple. Just a good snug fit. Once you feel it come snug add 15 degrees of tightening motion with a wrench.
Attempt to light the pilot... wait 45 seconds to 1 minute while holding the pilot button down before letting it up. If it stays lit.... GOOD JOB. If it goes out the next step is to replace the thermocouple. If after replacing the thermocouple it does not stay lit the remedy is to replace the gas valve. There are no short cuts and the sequence of repairs is just as I stated in order.

You can remove your old thermocouple and walk in to almost any appliance parts supply or Plumbing and heating supply to purchase the correct thermocouple without a part number. They will match it up with yours.

Thanks for choosing FixYa,
Kelly

How to clean a pilot light part for a delonghi gas portable heater


Try using an old toothbrush, as it is stiff enough to clean most of the deposits, yet soft enough not to damage the thermocouple and flame seat. Just make sure that the unit has cooled down first!

I have a reddy wall heater The pilot light goes on but has a foot and a half flame that wont go down ive blown out all the lines could you please help


James I am thinking either you have just installed this heater or you may have just cleaned the pilot ods assy.
If the flame is this long and large then it either has a enlarged pilot orifice or possibly have the wrong pilot on the unit.
What is the model number of the heater....what is the background of the heater and problem.

Older style Rinnai gas heater pilot light flame very large more yellow then blue..approx stays at 4inches even once burners are lit. Heater has 6 small burners and a brown cover.


not a problem. however, if you want to shrink it down... it's hard to say just what your gas valve is like. There should be 2 spots on it for adjustments, the larger slot (should be covered by a brass plug) adjusts the main burner output, the smaller adjusts pilot output. crank it down and watch the pilot shrink, but in this situation bigger is better. the pilot creates an electrical signal that opens the gas valve, you don't want that signal to be too weak.
It would be wise to clean the pilot supply, to have a cleaner flame. pressurized air does well with out having to remove it.

How di i light the pilot light


Be sure that the gas line to the heater is ON.

Looking at the Control Knob on top of the heater, you note that he knob has 3- positions: OFF, Pilot, ON.

Turn the control knob to the Pilot position and push down on it. If it does not go all the way in and your do not feel strong pressure pushing back at you, it is not directly in the pilot position. (Reposition the knob slightly and try again). Once You're sure the knob is directly in the pilot position and the knob is depressed, continue to hold it in and press the Ignitor button next to it. You will hear a loud click. If possible, watch the pilot assembly inside the heater when you do this. That way you can see if the pilot lit the first time. If not repeat, pushing the ignitor.

If the gas line had been turned off to the heater, the pilot may not light the first couple of tries, due to air being in the gas line. If that is the case, hold the control knob in until you smell gas, let off, wait 5 minutes and repeat the lighting sequence.

Once the pilot does light, continue to hold the control knob in for 1 minute. This will allow the Thermocouple to heat up completely. Ease off the control knob and the pilot should remain lit. If it does, turn the control knob to ON and the burner will light.

Now you're ready to set the temperature or comfort level. You do this by raising or lowering the flame height. The higher the flames, the more heat it puts out. The lower the flames, the less heat it puts out. The stripe on the knob represents the flame heights - Narrow stripe, lowest setting, widest strip, highest setting. Or your specific model may simply say Low, Medium, High.

If you do not have the Owners Manual for this heater go to http://www.desatech.com/
click on Wall Heaters and enter the Model Number of your heater. You can then download and print the Owners Manual.

Hope this helped to get you up and runnig.

My therma gas heater will not stay on . It ignits correctly, it also steps up to 3 pannels burning correctly, but you have to hold the grey gas button down for it to work. The pilot-type flame will not...


You need to replace the thermocouple. This is a small metal rod that is positioned in such a manner that when the pilot light is burning, the flame is contacting the thermocouple. When heated by the flame, the thermocouple produces a very small amount of electricity that it sends to the gas valve. The valve then interperets the electricity as confirmation that the pilot is burning and it is safe to conitinue delivering gas. Thermocouples wear out and stop producing power. The gas valve thinks that the pilot has gone out and thus turns the gas off for safety.
