Hello friends We got to take out our new rig this past weekend for some fall camping. Its a highland ridge lite bunkhouse. The furnace will light and run for a few seconds then shut off. Then it will relight and run for a few seconds and shut off this just keeps on repeating. I know its under warrantee but both the dealers are over an hour and a half drive each way. I was wondering if I can fix it myself or possible my local furnace man?

Sounds like the 'flame proving' signal is not returning to circuit board
Spark Electrode provides high voltage spark to ignite the gas and is then used a pathway for 'flame' signal (flame rectification) to circuit board
W/O that signal circuit board shuts down DC to gas valve so raw fuel does not accumulate

Could be as simple as spark gap (too wide/too narrow the milliamp signal gets lost)
Could be circuit board issue
Could be spark electrode wire or wire connection
Could be loose wire connector on circuit board

What Brand/Model is the Furnace???


Is it time for your medication or mine?

Old biscuit good.

I had a solenoid valve go bad in mine. It was doing similar while it was in the process of going bad. The burner was not getting enough propane, there would be a little propane at first, enough to light a flame, but then would run out of propane bc there was not enough pressure going to the burner, so it would shut off, then I guess a little pressure did build up in the system by the time it lit again and it could burn for a second but just go out when starved for propane.(Im not sure if this was what was really going on but was just my theory).
I replaced the valve.

I guess if the pressure feeding the furnaces is too low this could happen too. Unlikely as I am assuming all your other propane things work just fine?

How old is all this?
Regulators do go bad after a while. 15 years is a long time for a regulator.

Check with your warranty Co.To see if they'll cover a mobile tech coming out to you & repairing it. Of course, check with the tech to see if he does warranty work.

Wrestling a furnace out is out of the question for a waranted unit. Buy an electric heater until you get it to a dealer.

Try closing the valve on your propane tank and bleeding off the pressure, then open the valve very slowly. It sounds like you might of trip the excessive flow protecion valve.

I've had this happen. If you trailer has no propane pressure when you hook up a tank, then you open the tank quickly, it'll do this. Stove will make flame, though it's weaker. Big appliances won't work.

OP - Are you getting airflow? Does the air warm up at all? I've seen some trailers where the intake was blocked, causing the high temp circuit to trip because there wasn't really air moving through the furnace.

Or,, maybe all his outlet ducts are covered so that no air can get out of the furnace.
