Question about Desa International Blower Glow Warm Wall Heater

1 Answer

I have a Glo-Warm 25,000 Btu Wall mount heater Model F8S-SC. I can not get pilot light to stay lit. If I use a lighter, it will light, but when I turn it to the on position the flame goes out. I got it to burn for about and hour, but when I turned down the temp button it goes out.

SOURCE: glo warm wall heater will not stay lit

Hi Cindy,

It seems that your heater is not sensing the flame is lit and is shutting gas supply off. There should be what is called a flame sensor, it is a thin pc. of metal that sticks out into where the flame when lit.

This usually gets charred and dirty, if you unscrew it and clean it with a soft cloth then re-insert it, it will get you by. You should get a new sensor when you have a chance.

Good luck and be sure to disconnect from any power source or turn unit completely off when orking on it.

Thanks,
Paul

Glo-Warm Model #WMN20 20,000btu. Can hold down and ignite the pilot but as soon as i let go the pilot goes out and with out igniting the unit.


WITH THE HEATER OFF, clean the pilot flame unit with a can of compressed air. Blow directly into flame hole then try it again. if it continues to "not" stay lit then you need a new thermocouple.

It sounds like the thermocoupler is either not adjusted into the flame properly, or you may have gotten a bad one. The thermocouple is the main thing that makes the pilot work.

We had a problem keeping the pilot light to stay on, and this site recommended that it could possibly be the thermocoupler that was causing our problems also. We ordered the thermocouple, put it on,hooked it back up and it worked great! Thank you so much.
ordered thermocouple from www.masterparts.net
