They actually never have ice or frost on them, even when the freezer needs defrosting. But I've always has 12V fans mounted to them...

Thanks Vern, but I constantly monitor the internal temperature of both the freezer and the fridge with temperature gauges. I also have them alarmed for high temperature, which has saved our bacon when the propane unexpectedly runs out. (The freezer varies from between -5 degrees to +5 degrees, while the fridge varies from +38 degrees to +42 degrees over the course of the week.)

Oh boy, I also found out that there is a 12V DC heating element! I'm so confused!!

And I also wonder if (solar powered) boondocking is causing the extreme build-up of frost in the freezer, since that heating element is 120V, which is only available when we are in an RV park through shore power (which is only about ten days a month).

Thanks Wrknrvr and Kirk! Looks like there is a heater element off of J7 and 8. Do you think that heating element 'J' is on the right-hand side of the freezer compartment?

Wow Kirk and D&J; fantastic pointers!! I'm going to see if I can access the right side of the frig through the RV's wall (maybe cut an access panel) and see what in the heck is up. I'm also going to download the service manual and see if any heat generating parts are near that right wall... 👍

Thanks guys. We have to defrost this frig every six weeks, even here in Arizona. It's due next week when we hit a RV park.

As shown in the pictures, there is a bubble on the right-hand wall of our Dometic DM2652RBX propane/electric refrigerator. The frig has been in constant use for 3 years of full time RVing, and we only just noticed it. The bubble is not hot nor warm. Is this dangerous?
