K'.... been experimenting with the fridge the last few warm days. The coach is backed into my driveway and the fridge side faces due south.

Set on AC or 12 volt I can come home after 24hrs and the temp in the fridge is a perfect 35-36 degrees.

Set on propane after running for 24hrs, checking the same time when I get home from work it is 45-46 degrees in the fridge.

I am thinking it is not a ventilation issue.

Suggestions?? I don't have the manual for this fridge.

It could be the orifice for the flame. It may be partially plugged or dirty, I would also check the propane pressure which should be around 10 or 11" of water.

Not sure how to check the pressure, can tell you I can hear it go "WOOF" when it fires up and can hear it burning from inside the coach. Sounds pretty much the same as the Dometic RM660 in our travel trailer.

If the orifice (not certain where that is on the fridge) is how you described, what would be the recommended way to check it?

Thanks Bob,

Jared

Jared,

Here you go: http://bryantrv.com/docs2/docs/600.pdf

This is an absorption fridge that uses either 12vdc / 120vac / propane to heat the gas that is used and the propane mode SHOULD be
the most efficient.

I glanced through the manual above and there are detailed troubleshooting sections that you can use to isolate the cause.
