You likely have a bad thermocouple. Go to a hardware store and pick one up. You will need to shut off your furnace and remove the little copper wire that goes into your gas valve where you are holding down the button to light the pilot. Don't remove the larger silver tube that is for your pilot valve to supply the gas to the pilot.  Follow the copper line and try to pull straight down out of the pilot assembly and it may slide right out. If it doesn't you will need to remove the pilot assembly so go ahead and remove the larger silver tube from the gas valve as well. Take out the one or two screws mounting the pilot assembly usually a 1/4 inch or 5/16 nutdriver should be the proper tool.  Once removed unscrew the thermocouple and put in the new one. Reassemble. Careful not to bend your silver pilot tubing too much otherwise you will need to replace that as well. Always check for gas leaks around your pilot tube after reinstalling parts.

Pilot light ok when release finger pilot goes out


Your thermo couple is bad. Thats the copper tube that goes from the gas valve to the pilot. It senses thats the pilot is lit. Thats not working thats why it goes out. You can get a new one at lowes or home depot for about ten bucks its pretty easy to change just dont kink it when you put it in. It will just plug in at the pilot and screw in at at gas valve.

Pilot light on a Glow worm economy plus ep50b goes out of a night about once a week? thermocoupler has been changed.


This may be a case that the pilot needs cleaning. And recheck the thermocouple connection at the gas control valve. If the connection can be turned with your fingers, it's loose and needs to be finger tighten and turned just 1/4 turn more with the appropriately sized open end wrench. Conversely, it may have been overtightened when replaced. Loosen it, finger tighten it and only 1/4 turn more with a wrench.

Any or all of the above should solve your problem.

Turns itself off


If the pilot is turning off too, it's an indication that the Oxygen Depletion Sensor (ODS) may be clogged with dust, lint or pet hair. This happens because your Vent-free gas heater uses interior air for combustion and whatever s floating in your household air during operation is going into the heater and clogging it up.

If you still have your Owners Manual, follow the instructions for removing the front half of the cabinet, Be sure the control knob on the top is in the Off position, before removing the front half of the cabinet.
Here's what you'll need to clean the interior and it's parts: A vacuum cleaner that has a hose and brush attachment, a can of compressed air with a straw nozzle (like you clean your computer with).

Once the front has been removed, vacuum all of the interior, as well as the burner, that you can gently reach with the brush attachment. Once vacuuming is complete, look at the pilot assembly (it will be next to the burner). With the can of compressed air with the straw nozzle attached, place the tip of the straw nozzle barely into the pilot opening (were the pilot flame comes out and give it a quick blast of air. Now, look down the pilot from where the flame come out and you should see a small hole in the side or top of the pilot. That's the ODS sensor. Place the straw nozzle tip just barely into that hole and give it a quick blast of air. That should blowout any debris that's clogging it.

Now, look for the Thermocouple. It will be either a stand a lone thermocouple (A thin brass rod in front of the pilot flame opening. Or wire soldered to the side of the pilot near the pilot flame tip). Trace that wire back to the control valve at the top of the heater cabinet. It's a attached to the control valve with a compression nut. Try loosening it with your fingers. If you can turn it with your fingers, it needs to be retightened with your fingers and with the appropriately sized open end wrench tighten only a quarter (1/4) turn more.

Reassemble the heater and try lighting it as you normally would. If the pilot lights and holds, wait one minute before turning it to the on position. If everything works as designed, what you just performed solved the problem. Remember to do the servicing and cleaning annually. Usually in the Fall before firing it up for the heating season.

Williams debonair wall heater + pilot light problems


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!
