New RVer, need Help with a Dometic Fridge.


New Member
Hello All!
First time poster here, so my apologies if I'm not in the right area of the forum.

My wife and I just purchased a 2020 Keystone Premier as our 1st RV.
I'm having an issue with the Dometic DM 2672 fridge.
It works fine on LP, but not on electricity.
I checked the 5A fuse in the control module, found it was blown, so I replaced it thinking I had the issue fixed.
To insure it was, I turned off the propane.
The check light and warning beeper soon started in.

I just rechecked the fuse, it's good. It is a time delay fuse, by the way.
I checked voltage to the heating element. It's got 117v, per my meter.
I checked resistance of the element, I got a reading of 40 ohms which is in range of what I've found.
It was pulling between 2.3 to 2.5 amps, which seems reasonable as well.

Checking it now, after 30 minutes or so, it IS cooling, but the alarm is still sounding.

Any ideas?

Thanks in advance!

So, some more time spent on the googler says that in Auto Mode, the alarm will sound if the propane is turned off.
I've turned the propane back on, no alarm.

Seems like a terribly thought out plan.
I want to be certain it's running on shore power vs propane.

Surely I'm not the first.
Is there a workaround?
