    Dometic model rm 2852 (on the inside of fridge) model number on cooling unit 805A. The freezer works but not the fridge.

    There is no fan, it does run on a differenent system.

  • Janet Crider Jul 15, 2012

    The information I got was good, I did find my fan that was conected to the thermal sensor was not working and it blew the fuse. Repaired the fan and replaced the fuse first (before I remove the fridge) and now it seems to have fixed it.

You have to send the brand name and model number so i can help you.all that happens is the evapcoil in the freezer gets cold,the evap fan motor blows cold air from the freezer into the fridge side,depending on your model you could have a bad damper,this is a door that is in the fridge section,it opens and closes letting the air come in,try this,open the freezer door,if you don't hear the fan blowing you could have a bad fan motor,also touch your hand on the back inside wall of the freezer,if you have frost or like ice on the back wall you have a defrost problem,ice is biulding up on the coil and the fan can't blow the air over to the other side..if you need more help,do these tests and send the model number off of the machine and brand name,side by side or freezer on bottom,open the fridge door,look up on right hand side wall near ceiling or on ceiling,freezer on top look on left side in fridge section.

    janet,i'm sorry,i thought it said you had a domestic fridge,i don't know about rv fridges but i can't see it being that much of a difference,like i said the cold air is blown over from the freezer to the fridge side with a fan,check to see if the fan motor is bad,another thing that happens if the fan is bad is that heat rises so the bottom half of the fridge and freezer will be colder,if you shut it down for a day all ice would have melted so check the fan motor,on a regular machine when you open the freezer door you can hear the fan blowing,not sure on yours,you can check the fan motor with a meter,sorry and hope some of this helps you.

    you can check this out,i googled it for you,if you read the bottom it sounds like you have a blockage in the vent where the air passes through
    My 28 years in the RV service business says that you have a blocked cooling unit.
    Your description of the trouble is a classic sign of cooling unit failure due to blockage, as someone else mentioned.

    With a blockage, there will be no leak so you will not smell or see anything. There are small tubes that go between the freezer and the refer section and pieces of the epoxy coating that line the inside of the cooling unit tubes can flake-off and become lodged in these tubes.

    You can remove the refer and "burp" it buy turning it on each side then the top then bottom, for a few hours each side. This will many times dislodge the blockage and return the flakes of epoxy back down to the boiler where hopefully they will remain.

    I have used this process many times over the years and many times it has worked. Some it was only a temporayr fix but others lasted a long, long time.

    Other than this, the cooling unit will need to be replaced. sorry again and hope this helps

try unplugging it and allowing it to sit for 24 hours or so to allow the refrigerant and compressor oil to settles. then retry. If the filter got plugged you will need a refrigeration tech to repair it.

My Dometic trailer refridgerator is warm but freezer is freezing.


Brandi4723,

Unfortunately, you have a bad cooling unit in your refrigerator. Then ammonia smell means that you have a leak in the unit. TURN THE FRIDGE OFF!!! Do not use the fridge on AC or Gas until you have the cooling unit replaced or buy a new fridge. Depending on the model number and serial number of the fridge, it may be under recall by dometic and you might be able to have it repaired for free. If you will provide me with the model number, serial number and the serial number of the cooling unit (found on the outside of the unit in the fridge compartment, lower tank of cooling unit), I can then tell you the pricing of the repairs or whether it is under recall.

Again, TURN THE FRIDGE OFF and do not use it...RISK OF FIRE!!!!

Hope this helps,

Jeff

2002 RM 2852, the refrigerator (lower section) will not work its warm inside, but the freezer (upper section) works fine, it will freeze water bottle to hard ice. All fuses are good. Please help!!


cooling unit is bad my friend there is a temporary fix but in my opinion not worth your time take the unit out and flip the refer upside down this sometimes dislodges the blockage in the cooling unit all a rv fridge is is amonia and salt if not used all the time the salt crystalizes in the orfice and blocks the unit a rebult cooling unit 550 about and labor 4 hours at your dealers rate a new fridge about 1500 installed
my shop 360 for labor 550 about for unit 910
I ALLWAYS RECOMEND REPLACING THE FRIDE COMPLETLTY
you get all new electronics and a new box

Our rv refridgerator/freezer was turned on for the first time since we bought our rv and when the freezer was opened it had a terrible smell of amonia that about knocked me over. Is that smell free on or...


thats because yoiu have a amonia system thats why they say to keep it level to opoerate properly. the smell may be a leak from where someone punctured the evaporator.

Fridge not cooling


If you look in the outside compartment do you see a yellowish powder? If you do, or if you smell amonia probably the cooling unit has leaked the coolant. It does not help to add coolant, it will just leak out again quickly. You will need a new fridge or to have the cooling unit replaced. If that is the problem, Dometic has a recall on some models for leaks and will pay for a new cooling unit.

Tuna, it sounds like your thermistor is bad. Once the fridge reaches 40 degrees, the thermistor is supposed to tell the board to stop cooling and maintain. You can test it with an Ohmmeter.
