Thanks for the response. It was really over my head but I think I understand in general what you are saying. So we just returned from our weekend camping trip. We were on battery the entire trip. Once I got our trailer setup the first thing I did was check the heater and nothing worked, just the blower motor. Batteries were fully charged, I checked prior to leaving. The next morning I tried again, no go. So I went ahead and tried the ol give it a smack routine and bam, after two to three hits on the top just after starting the heater the I heard the igniter kick in and out comes the heat. Tried it again the next morning and same thing, had to tap it on the top again before it would work.

This to me seems like it is a bad connection, but when pulling off the front panel I can't see much. Do I need to remove the entire unit and open it up?

Any ideas?

Since you are banging on it to get it to work. It could be the sail switch or the circuit board. Yes, you have to pull the heater to get to the circuit board and the sail switch.

Your gas solenoid could be corroded.


Try momentarily applying 12 volts directly to the spade terminals on the solenoid to see if it "snaps" open reliably. Try this several times. If it hangs up even once, it is your problem.

Admittedly this is easier to do with the fridge, but the principle is the same.

A backup Buddy Heater is a good idea! To keep the wife happy! Lol
