I don't have any idea why this fridge is draining your battery, but I have another suggestion. My Dometic will get reasonably cool in around 4 hours, so I pack it with cold food and turn it on at the same time. Yours may do the same.

I'm not sure about a door condensation heater....how would I check and turn off if so?


Look at the schematics for the fridge. Mine has a heater/light (the light in the fridge) 5A fuse! It was killing my battery every night! I pulled the fuse, and bought a small motion sensor light ($5) at walmart and put it in the fridge. Problem solved!

Good luck!

yup, but I am wondering if it realy is.. no way it should drain a batery when its on propane in 4 hours, unless the battery is already dead.

Even tho he has a 2022, that does not mean his battery is GOOD. It could be out of water(boiled dry) or partially boiled and has no reserve power. Doug

I installed a switch on my propane/CO detector to turn it off when we are not using the TT. I also installed a battery power smoke/CO detector and a battery powered lp gas detector. We also installed a switch to turn off all power to the radio because I don't need a bright blue night light to stay on all of the time.

Well, we have found a solution. We tried two things as we prepared for this weekends camping trip.
1) we turned off every circuit breaker except the converter and the fridge
2) we swapped out our 12v battery for two 6v batteries.

Started the fridge on LP at 10:30pm. At the time batteries were reading 2/3. Left for camping at 3:30pm the next day and the fridge was cold and the batteries were still reading 2/3. Not sure if one of those two solutions was the trick or if it was the combo. Frankly, I don’t care. It works and it’s an easy solution. This will be our game plan going forward, as well as disconnecting the battery at the battery, not with the factory switch off.

Thanks everyone.

Thanks for following up with this. I wish everyone did.

This implies you do not own a voltmeter. Your 12V troubleshooting ability is handicapped without one. It's $15 well spent.

One battery in a big 5ver is just the mfg or dealer being cheap. Plus assuming it was a normal 100ah ish battery, even if perfect, the 2 6v more than doubled your useable battery capacity.
However, when troubleshooting, if you make 2 changes at once, you are not really figuring out what went wrong. However performing your test with the breakers on again is easy.
