Glo warm ventless heater will not stay lit more than a few seconds burner not pilot lite

SOURCE: gas heater

Mae, It sounds like you may need a new thermocouple and maybe your pilot needs cleaning. If you are mechanically inclined, you can remove the old thermocouple and take it to Home Depot or Lowe's an they can fit it to a new one. To clean the pilot, you will need a can of air used for electronic equipment. Remove the pilot assembly and shoot a stream of air through where the gas line was hooked to it. This will dislodge any debris caught in the orifice. Do not shoot the air from the pointed end as it will blow out the pilot orifice and you will never find it. Using a soft wire brush or stiff tooth brush, scrub all other pilot components and make sure there is no carbon build up an anything.

Hope this helps!

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

Look for and clean the flame sensor.

SOURCE: pilot stays lit, but burners underneathe do not light up or burn.

Check pump is working, if so could be stuck flow switch or gas valve fault get unit serviced

haven't had much to do with heater brand but have with pilots it sounds like the thermocouple is either not tightened into valve properly or that it needs replaceing they will burn out over time and usually just a simple replace will fix but you must call service agent if you are not yourself to do this for you as it may be the valve itself which means replaceing that which you must be quakified gas fitter to do even the thermocouple should be done by a competent person as it is a gas heater!
