Do you have a small battery operated refrigerator fan? I have always used this and adjusted the cooling sensor along with an refrigerator themoter. This seem to maintain the refrige temps. I always traveled with the refrige on auto this will allow the unit to switch between propane and electrical use.

Its a 4 door frig and no it does not have a fan . I always run on auto so it will switch in case electric goes out. I have run it on only gas and it still goes up and stays. It usually runs 32 - 34 . It has finally gotten down to 39 . It started up about 4 Fri and now Sat evening. It may be 33 by morning. It has done this since it was new a year ago.

that sounds like a floating blockage. does it do it on propane as well? will it do it with the vent covers off? id look to see unobstructed air flow over the coils. then be sure I was level. you can wire the heater elements direct to 110. that would be the standard test that should have been performed by the dometic center to test the coils. when wired direct, if the unit warms intermittantly its a core issue. floating blockages usually occur when a refer is operated out of level, but the mfg honors warranty.

The outside temp was about 82 degrees when we left home and thought since going only a short distance, could travel with frig turned off. When we reached our destination the inside frig temp was 42 degrees. What might the problem be?
Meanwhile, back at the OP's thread...

I don't think you have a problem. At 82 degrees OAT and depending on the airflow around the RV and especially in the vicinity of the external vents, a rise of 10 degrees does not appear to be exceptional. It is consistent with our our experience. We used to run with gas on to safeguard those precious perishables. No more. The potential implications of being in an accident with gas plumbing full of pressurized propane is significant. So we don't. We've successfully kept the reefer at acceptable temperatures with strategically placed ice packs for upwards of 10-12 hrs in summer time temperatures.

the fittings that hook to the LP tanks are "excess flow POLs". take the hose off a reg and hook it to a tank sometime. if you throw the valve open you wont get squat for propane. its perfectly safe to travel with it on. if you have a line rupture a plunger shuts off the flow. and I score a double thread jack...

We have auto level so that can't be it. Have had both mother boards replaced and coils are ok. Added insulation and ran on an outside battery for a week as per Dometic instructions to repairman. Nothing has worked. So I am going to show my temper Tue. and get a new frig . It's has not worked right since new. Dealer has been worthless so kicked them down the road.

Still have not gotten new frig. Dometic was suppose to call back this week but of course no call. It's been over a year. Has not worked right since 1st trip out. Not sure what good a warranty is. It is under warranty but means nothing to the dealer, FR, and Dometic.

I have a 4 door Dometic and mine works better off electric than on propane. Our stays at 33 deg. on electric and 35 to 38 on propane.
They should warranty your fridge. no question.
Have you tried it both ways to see which works best, propane or electric. On electric there are 2 heating elements if one is bad that would explain bad performance. If it works bad on propane then low gas pressure could be the cause. Kink in gas line possibly or faulty regulator.
Hope they fix it for you.

It works about the same on propane but the temp does not go as high on propane. It has stayed on as high as 53 for up to 48 hours. The last time out it was 46 for the high and 36 hours before it got back to 33 on electric.

This is what I was asking about.

Fridge Airator - Camco 44123 - Refrigerator Accessories - Camping World




This solved my issues with the propane/electric refrigerator not keeping the items stored in the unit cold enough. You need to move the air around in these units in order for the cooling process to work efficiently. Just like your home refrigerator has a fan in it to move air these units need one also. But they are not made with one. Why? I do not know. I used this on my last two 5er's that had the Dometic in it and the other had a Norcord refrigerator in it.
