Pilot light keep going out will sometime stay on 3 hours then go

I have a continuous problem with my Coleman Evcon 7900 series.
The pilot light will light fine and the unit will work for a while then the
light goes out. A professional technician have replaced parts and cleaned out the pilot light debris. It worked fine for 8 hours and the pilot light went out again. The technician return and the same problem still
exist. What can be causing my pilot light to go out?

    The thermocoupler and flame sensor was replaced. Also, the pilot and oriface

    was cleaned. The heater pilot light stills goes out. I attempted to light the pilot and

    the flame went back out. I waited 5 minutes to relight the pilot and soon I entered

    pilot door with the match the flame busted out the door. I was very fortunate I was

    burnt on just my hand. I will call another technician in the morning.

    Accurate Joe what appear to be the problem with this pilot light.

    Pilot light only stayed for 3 hours after it was lighted. New sensor has been installed, but it didn't fix the problem.

Great, if you are not skilled in working on this type of appliance the best thing you can do is to call a professional out. Be careful in picking a service company, there are a lot of dishonest people out there. Try to get a reference from somebody in the construction trade that you trust.

Pilot light lights but will not stay lit with full Propane tank.

Unscrew the thermocouple at the gas valve. Lightly sand the connections,seat and thermocouple end. Sometimes the tiny current generated that keeps a gas valve open will be diminished by corrosion. don-ohio

Lighting the pilot, starting the fireplace

Turn on the gas, hold the pilot flame button down and light the pilot flame, continue to hold the button for at least three min's, release the button pilot should stay lighted.

My Coleman furnace 4322/729 model lights the pilot but won't cut in . What could be problem ? Cleared lines Complete

Gas valve not opening? Does it have the exhaust blower that pulls vacuum switch allowing burner to light?
(1) Thermostat not working? Has to complete the circuit in or gas valve to open.
(2)Can be a stuck or bad gas valve. Try tapping the side of the gas valve body while thermostat is calling for heat. Tapping,not pounding. Like lightly,yannow? don-ohio (:^)

Cannot get gas to flow to pilot flame with main valve parallel to gas pipe. Is there something I must push to make gas flow to the pilot flame pipe?

you said, in effect: Cannot get gas to light the pilot flame even though manual supply valve is open. Is there something I must push to light [ignite] the pilot? Permalink
The gas supply valve is open, and the pilot gas cutoff valve is open but [it seems like] gas will not flow to the pilot flame because it will not light when I supply a match or lighter flame. I remember there is a button or something I need to press...but where it it? I cannot find it.

I have a Coleman Evcon electric furnace, the blower fan runs constantly and I have to shut the breaker off inside the front cover to turn it off. The switch is on auto and it runs even when the thermostat...

It could be a thermostat problem. Also it will seem to run constantly as it tries to heat and one of the elements are working which could be a sequencer problem.
