Love this guy!
Great video. I'm having issues with my Norcold 663 in a 1995 Callista. This was very helpful!
Excellent video
Thanks
Mine isn’t cooling well and incapable of freezing. 48 is the best I can get right now. Based on what’s in this video I’m betting it’s a blockage but I’ll look into more later. I haven’t seen or smelt anything and the airflow is set up correctly.
Hello again from South Texas Darren great video. Do you suggest if cooling coils are rusted out to remove rust and repaint them?
Not really, it doesn't really matter what the outside looks like. The inside is probably still working just fine. So no, I would not worry about the rust on the outside of the cooling unit.
I have the Dometic 2454 The refrigerator does not get very cold The freezer works excellent, I have to crack the freezer door which is inside the fridge to help cool the fridge. The thermistor checked out okay and have adjusted it up and down the fin with no change. Had an RV tech check all the electrical everything checked fine.. is this a case if I need to pull it out and turn it upside down and reinstall..? Also it doesn't matter whether I have it on 12 volt, 110, gas..
I have a Norcold 811. That stopped working when we went away for a weekend and I turn off the power supply. When we came back it was not cooling the refrigerator or freezer. I detach the thermostat and nothing changed. Any ideas?
Just curious but on a dometic rm2351 any idea what it should cost to replace the cooling portion or the whole unit?
Hi Darren, I have a relatively new 12v fridge ( jan '24...dometic dmc4101). Came back from vacation about a week ago freezer fine, fridge about between 60 and 70 degrees! Other than warranty work would you have any ideas?
Thanks David
I just bought a 98 Sportsmaster, the freezer works perfect but the fridge portion doesn't cool. Any tips? I'm new to the RV life and learning as I go.
Hi, Did you fix the bottom part ?? I have the same problem
My RV wasnt leveled. On driveway. Had to bring it down for it to work.
Hi Darren. I hope you are doing well. Been crazy here.
We've had a nice comfortable pace throughout the winter. Keeping folks in the hopper. Not as busy as previous years though...
Question, my dometic refrigerator is about 26 yrs old, freezer is building ice on back wall of freezer, at the same time, when outside temps go over 75°,, the refrigerator not the freezer, struggles, but when temps are cooler then 75° ,, I have 34-36 in ice box, that's the lower box for the milk.
What do you think might be going on..??
Thankyou for some input.
I am thinking, I should replace the the whole unit do to it's age ??
👍👍
Get a Residential Refrigerator that's Self Defrosting and more Reliable especially if your Full time....:) It's Cheaper and more Efficient.... Propane appliances these days are old Technology with the introduction of Stand alone Power Stations.:) RV Appliances don't last and are extremely Expensive to replace every 5 yrs maybe.... 👀
Could I have a blockage if it works on propane but not on electric?
Not likely, a blockage is a blockage in the cooling unit regardless of the Heat source.
If it's not working on electric, you can follow the 120v AC trail. Verify you have AC power feeding the control board, then through the glass fuse on the control board. When the refrigerator is calling for the boiler to turn on with AC, you should have 120 volts on the two pins that the heating element connects to. You will need to disconnect the heating element to get a voltage reading on those two pins. Then you can check the Ohm's value of the heating element (at ambient temperature) and compare your value to the service manual. On our website under the resources tab we have many service manuals for refrigerators.
None of this applies to 12v residential refrigerators and why they aren't cooling.
