Dometic Refrigerator-- Problem on 120 VAC

6 posts in this topic

We have a Dometic model #RM2852 2 way refrigerator. The coils on the back will get hot when on gas, which tells me it is working good on gas. The problem is with 120 power. The heating element will get hot, but the coils continue to be cold, even after 1 hour. Never took that long before, just started having the problem. I was wondering if I am correct in assuming the problem is with the heating element, or should I look elsewhere or take it for service.

Hi Bill, I posted this information about how a Gas / Electric refrigerator works. You might want to read it over.

I will ponder your issue a little longer in the meantime.

Bill, When you mention, on electric the unit remains cold. Do you mean warm not cooling?

Is your refrigerator mounted on a slide or have a sidewall vent ?

The problem could be the fans installed behind the refrigerator are not running. Could you post if it does have fans and a side vent or a roof style vent?

The coils on the back of the refrigerator remain cold and the fridge does not cool down. The heating element does get hot, but doesn't cool the fridge. It does't have fans and the outside access door is vented along with a vent on the roof. The coils on the back get hot when on gas, but not on 120. Thanks for your reply.

Bill, this is a link to the DIAGNOSTIC SERVICE MANUAL that should cover your unit.

You might want to clean the contacts on the lower control board, that is mentioned. Use a clean pencil eraser to clean the contacts, rubbing them lightly to remove any oxidation.

This is a link to there Service Tip manual. Shorter version of the other manual.

Allegiance, No real secret, Just perseverance in most cases. Using multiple search engines and different word combinations.

Just been using the internet over the years for fun and work related needs for information.

Sent you a PM if you would like to respond.

Rich.
