Warm Refrigerator

Hardly a news flash but I've never been very happy with our Dometic four door refrigerator. The temps in hot weather have been a challenge from day one and never had anyone give much help with it. We are in Fl and the temps are averaging 80-84 the last week or so. The fridge was up to 45 and I decided to get the ladder out and take another look. The top vent was where I found a issue. The insulation which is the pink fiberglass was laying on top of the top cooling coil. I thought this was ok but when I got a closer look I could see that air was restricted from going around the coil like it should. I couldn't find a good way to fix it so I took a piece of cardboard and cut it to fit and slide it on top of the coil. It keeps the insulation 3-4 inches from the coil and has so far kept the temp in the 35-37 range.
Its worth a look if you are having problems. The cardboard might not be the perfect fix but will do until I get home. The next step will be to add another fan{there are two now] but I'm hopeful this will do it.

I don't have any problems with mine, but this is a great tip. Thanks for posting.

Might try Lowes/HD for some alum. flashing you can cut with scissors in lieu of the cardboard. Where are you in FL?

Great trouble shooting. 34 degrees is the low end of cooling in a fridge and 45 degrees is the very top end, I say you corrected the issue

I have 2 fans at the bottom of the frig, just above the burner chamber and 2 fans inside the frig. Freezer runs consistently around 4-11 and the frig runs consistently from 31-34 with the temp control set @ 3, which is mid range on the Norcold.

IMO, the fans at the bottom work better than those at the top, but have no data. Just think cooling the whole tube assy is better.

Good idea on the alum there is. Home Depot up the road I will check it out. We are at Silver Palms in Okeechobee. Nice place Nd nice people. Here until 3/20. I fly to Mi this weekend for 3 days. What am I thinking.

Did you have the same problem with your refridgerator before they put the new roof on your MH?

Yes from day one. I had the dealer look at it and they found dotting wrong. I did seem much worse on this last trip but it's hot and humid so we just thought here we go. I was going call Randy to get a price to put a residential fridge in.

What size invertor do you have? When I inquired I was told I would need to change my invertor to a much larger one at a very high cost just for the invertor. At goshen when my refrig had to be removed the rep from Dometic came over to inspect the unit and found the LPG nozzle had to be replaced. Once that was done the refrig cools much better when on gas.

Marty I would need to also change the inverter and if have no idea what it would cost. Lots more than I want to spend I'm sure. I'm back to 38 overnight so my problems may not be over. It's on electric so the LP shouldn't enter into the problem. I guess I will watch it to see what happens. It's better than it was. I have the temp set on 5 and overnight the temps were 70 so it should be down to 33-34.
