Refrigerator not getting cold

I have the Dometic 2451 in my 2007 Safari. I had to replace my power converter, so the refrigerator had no power for a few days.

Power is back on now. Refrigerator is on auto setting. Freezer seems to be getting cold but fridge is not. Manual says it could take four hours and it's been at least that. Fan is not running but the switch is on.

The user manual is no help. Do these things just take forever to get cold from a dead start or do I have a problem?

Any suggestions?

When all else fails "Reboot". Try removing all power from the frig. Cut the AC and DC power let it stand powerless for an hour and then power it up and try again. Let it cool overnight and check it in the morning, that should be enough to get the cooling up to speed. If that doesn't work, it's warranty time.

Your refer if it has fins/blades on the upper shelf, you should see a sleeve on the right most blade. You should be able to move it up or down. This ishould be the adjuster for the temp of the refrigerator.

Which way do you move it to make it cooler...up or down? What does that do? I never knew I had that until I read this post. There is a wire attached to the sleeve...is that a thermostat of some sort? Nothing about it in my owners manual.
Thanks.

Wow, I never saw that either! I will have to check it out next time I'm at the trailer. I'm also playing with the 2451 (see the post about the Refer Switch). I think to some degree it helps to have something cold in the fridge. If it's empty or filled with warm food, that might work against you.

If you are experiencing the heat and humidity that 3/4 of the country is, IT WILL take a while. Make sure the fridge is level, side to side and front to rear. If you want to check it out, put a gallon of water in it and check it for temperature in 24 hours. Since the Rv fridge operates on a gravity principle and no compressor, it is slower than a unit that has refrigerant being moved my a compressor. Hope this helps...

Just installed a new NorCold and the manual says it takes 10-12 hours to cool.

Norcold has their owners manuals online . . .

That looks like a different fridge than the rm2451, but thanks for the greaat photo -- and I guess the slider thing is just the sensor. I can't image it makes much difference where it's located because the temperature differential across that blade can't be very high. My guess would be moving it farthest from the freezer would be the best bet -- if moving it does anything at all. You'd think the owner's manual would mention this if it was really a user adjustment.

The refer was colder this morning, but not what is should be. I've got the slide all the way up. Considering the 100 degrees in the shade temperature around here this week it may just be struggling to get cold.

Do you have anything in it?

google " Snyders rv refrigeration" . They have the fix for 40 bucks. These rv fridges only work for wine chillers when the outside temp is over 95F.

Can't tell from your first post if you have a three-way or two-way (running DC or AC). Have talked with those who are suppose to know, and they say things are not efficent running DC (true/not true?).

I also live in an area that has been hot for the last 1-2 months and did some testing to see how well my new fridge performed. I've attached a pdf to give some kind of comparison (might help?).

Wow Spiffy Gem, your fridge is working way better than mine, but mine is empty. If you are at 100F to 110F and are getting 40F in your fridge that's pretty impressive. I guess it might matter which way it faces (sun or shade). I'd be lucky to get 50F-55F under those conditions right now. I think I'm going to try one of these:
