Empire wall furnace problem

My problem is similar to this thread's issue but not identical. Empire gwt 35-2 propane wall heater. Professionally installed new in 06, not used many hours since. Have replaced thermostat once and safety limit switch twice, but still heater will work properly for 5-10 cycles, then main burner will not come on until safety switch is reset by hand. Thermostat setting has no effect on this problem. When safety switch is reset, heater works again for a couple of days, then must be reset again. Tech now saying, Oh these are just not reliable let us sell you something new.... Would like to keep this as it is still pretty new and used mostly as backup to woodstove.
Thanks

Welcome to the forums.

These gravity vent Empire wall mount furnaces seem to be prone to vent issues.
Actually I'm kind of surprised that a pilot type heater has a draft issue. The pilot should keep a small draft moving. (sucking the heat out of your house)

The problem comes down to a vent issue where the exhaust gas doesn't vent quick enough or the propane pressure needs to be checked and possibly be set at the gas valve. I'd have the pressure regulation checked at the gas valve to eliminate that as a problem.

Link to your manual... Empire zone heat/assets//EHS/manuals/GWT-(25,35)-3(SG,RB).pdf

Thanks, will get that checked and also inspect flue to eliminate that as a possibility.

Flue totally clear and clean as far as I can see, maybe 10 feet down from the roof vent cap (high wind model).

Pilot light problem? Thermo couple that tests if the pilot is on? Blower or fan blade is fouled and not pushing air causing electric motor to overheat. Heat exchanger is covered in dust and overheating.

I am not a pro and these are just guesses.

I have an empire wall heater. Pilot burns well until thermostat is turned up to kick it in then pilot goes out. I've replaced the millivolt and cleaned pilot. Please help
