Problem with heater
I need some help. On a first trip with my new bullet and the heater worked fine first few hours and then in the middle of the night it got cold. Got up and it was just blowing cold air. Cut it off for a minute and cut it back on and ran up the temp. It worked for a couple of cycles and did it again. It seems like in the cool off cycle it just won't shut off it just keeps blowing cold air. Got new propane tanks and can't figure it out. Please help if you have had this issue. It is on auto too

That is a classic symptom of being out of propane. I recently had a problem with a propane tank where it wasn't releasing gas. Try opening one tank at a time, testing the furnace each time. Of course, assume both tanks have propane.

Yes both tanks are full. Already thought of that. Tried switching tanks. Will see if that works tonight.

It is also important to open the propane tank valves very slowly.

Could be a defective board, or for some reason its overheating and going off on limit?

Have your model, date of purchase, and serial # ready and call Atwood direct. The 1st tech at Atwood I spoke with was worthless, the 2nd determined a tech was required and emailed a list.

I'm with Mike, it sounds like fuel starvation. Listen to it burn before it dies. Does it have a solid roar or does it get thready or fluttering before it kicks off? My first suspect would probably be the LPG regulator. I went through the same furnace behavior about a year and a half ago, and it was a bad regulator.

Don't where you come with fuel starvation when OP states after reset runs fine for a couple cycles then the fan keeps running?
If I read correctly brings unit up to temp will likely do a couple times, then during cool down can never shuts off. If that is the case likely a bad control board in the furnace.

I threw out a possible fuel starvation situation based on whats happened to me in the last five yesrs. I've had one primary regulator failure and an ongoing issue with the left tank step down regulator (5th wheel) which I finally removed. I missed the part about the blower not shutting off and no, fuel starvation would not cause that. I would also think control board or a faulty temp limit switch, which will behave exactly as described.

We have seen a rash of Atwood furnace issues. Seems more often than not, the control board has gotten wet. Atwood it seems has decided to move the board, and if the access cover isn't installed snug, water will get on the solder side and cause some weird behavior.
