Yep I have to remove my cabinet cover then the metal cover on the furnace itself. Once I do this the heater kicks in and runs without issue. I have the 233s so my furnace is under the sink.

Almost seems Asia there is not enough oxygen to kick on the flam, or there is too much air flow. I don't know if should try to fight with the dealer since it has been in before the warranty ended and was never fixed.

Anderson, I think we figured out how to replicate it. It only happens when the batteries are about 2/3rds full. So when the dealer gets it, the batteries are typically full. I'm gonna run the batteries down in a couple weeks and take it in.

If you can, try removing the little circular vent covers (that direct the air) and see if it works without them. We are using that as a temporary solution. My guess here is there is not enough air flow against a sail switch when the batteries are not 100% full and the resistance from the vent covers exacerbates the problem. Opening those vents (or as we discovered, the cover) lets enough air move through to trip that sail switch I think.

So either a bad blower, or a bad sail switch (or one that needs adjusted) I think is the problem.

I'm not 100% sure the high altitude has anything to do with it yet (low oxygen), but going to see about testing it when I get it home next time after I run the batteries down some (I'm at about 5,000ft, we camp at 8,000ft).

Weve gone on 2 trips in our Rockwood 2306. first trip was at 7000' on battery power and we had the same heater symptoms. We just did our second trip to a campground a few miles from the first place and had no problems with the heater but this place had 30A hookups....

Update with another 2 trips.

7000' campsite on battery power and covers on = heater will not ignite
7000' campsite on battery power and covers off= heater works fine
7000' campsite on shore power and covers on or off = heater works fine

We're still experiencing the same results as well jhoppmann. I've done 3 more trips, all around 7,500-8,500 feet... covers on, no workie. Covers off, works fine. Shore power, works fine.

Took it in again, dealer couldn't replicate the problem at 5,000 feet, even with a low battery. They think it's a voltage issue and wanted me to try to replicate it by taking batteries out of parallel and trying each individually to see if there is a battery problem.

I still think it's a sail switch issue, but dealer is refusing to send it back saying since it works fine, they'll be charged for it.

My video of being able to replicate the problem didn't help apparently. I'm going to escalate up to FR Warranty support directly.
