Hot and cold Dometic refrigerator.

Help. My 2010 Dometic refrigerator is acting up. It will work for weeks and then the temp. will suddenly go up to 60deg. It seems like when I then cut the power and turn it on after a little while the temp. will drop down to 38deg. That can go on for a good while and then it will stay cold for weeks again before it acts up again. The freezer stays frozen all along. Any help will be appreciated.

Hot and cold Dometic refrigerator.

Check the light. We were having trouble with ours not getting cold and I discovered that the bulb was staying on. How did I discover that? I touched the bulb when I opened the door and burned my finger. I do not know why they use such a high heat output bulb........

Short term solution, removed the bulb.

Low ammonia levels will do this.

Remove the outer cover and check for a leak. Look for greenish yellow stain.

I will check for leak. I guess it could be that it freezes up. I am camped at 10000 feet and it gets cold at night. In the day time the temps. are around 65deg. but often down to freezing at night.

My fridge did the same thing and I found my light bulb staying on inside my fridge. I removed my light bulb and though it in the trash. My fridge now stays at 34.

Is yours a four door model? We had a similar problem and it turned out that the vertical bar between the two doors wasn't flipping completely, leaving a gap through which cold air flowed. Wait 'til dark, put a lighted flashlight in the refrigerator, and turn out the lights in the room. If you can see light around the refrigerator .....

Have you made sure the fridge is completely level? These units require that it is level.
I would also check to see if the vent on the roof is clear and free of obstructions. The vent must have air flow over the external coils. Heat build up in the outside part of the fridge will kill the cooling effect.
And, I would also look for an ammonia leak. Yellow stains....
