SOURCE: my pilot light wont stay lit

Hi try cleaning the pilot light out make sure the thermo couple is in the flame,check where the tcouple goes in to the valve nothing stuck in there try this it could be the valve not working

SOURCE: Pilot works, will not stay lit

Check your tip switch by putting a jumper wire between the two switch connections. If your burner lights replace the tip switch.

SOURCE: i have a older Miller furnace(1989)the pilot will stay lit

Replace the thermocouple.

Try this, do you have a butaine stick lighter? Try to heat the thermocouple with it ... see if you can get the main burner to come on. If not - definitely, replace the thermocouple.

Thanks for your question.

It could be the thermocouple, but you have to take the head apart to replace it. If you got the main burner to fire, then the thermocouple is probably ok. Try changing the regulator, easy to do and not to expensive. If that doesn't work, try taking the head apart and cleaning the pilot and main burner orifices, do both while you are in there. If you are not comfortable doing this, hire someone.

Hi, this heater doesn't have a thermocouple, it uses a pilot generator which is more reliable so I doubt you need to change it out. First thing to check is that you have a clean "sharp" blue pilot, you should be able to hear it quietly roar. If it is yellow and appears "soft", the pilot need to be cleaned. The easiest way is to use a straw or tubing of some sort to blow into the pilot, gently tapping the pilot assembly. That should clean it up and heat the pilot generator properly. Tighten the the screw terminals at the control valve to assure good electrical connections and last but not least turn off the thermostat until you get a standing pilot. Good luck and stay warm.
