I have a similar problem with my dometic rm2554 refrigerator in my roadtrek.
Dometic rv refrigerator check light keeps coming on.
You are about to leave for vacation on your trusty rv and suddenly notice that the check light of the vehicle dometic fridge is on.
It will run on gas for 2 4 hours then the light will come on then i can switch over to electric stay safe and healthy.
Dometic refers from the mid 90 s had faulty control boards that would intermittantly throw the check light after attempting to light.
See how to solve a number of rv refrigerator repair issues yourself online repair manuals for dometic and norcold refrigerators and when it makes sense to replace instead of repair an rv refrigerator.
The d ometic rv refrigerator check ligh t is designed to goes on if there is something wrong with the gas system.
A common problem is when the refrigerator stops cooling properly especially after it hasn t been used in awhile.
To ensure that the fridge could achieve peak performance you have to find out the reason behind the check light activation before hitting the road.
It works fine on electric and 12v but will not come on or stay on with propane.
The check light still comes on we have it plugged into 120v power source and the panel between freezer and refrigerator is getting hot but check light keeps coming on.
Even when on auto and connected to 120.
Does this light have anything to do with refrigerator when it is runnung off electrical power.
Rv refrigerators can fail for a number of reasons.
I took it to an rv service place and they cleaned out the line and were able to get it running and stay running while it was there.
