Dometic Refer Fridge Portion not Cooling
I did a search to find this issue but turned up minimal. I have a 2011 Keystone Cougar 328 with a Dometic Refrigerator. The Freezer part seems to be cooling fine, but the Fridge might get down to ...
Forum Discussion
Actual Model of that Dometic would be helpful
120VAC issue....
Voltmeter
Check voltage at receptacle fridge power cord plugs into
Check voltage ON circuit board where AC Power connects
Check voltage on BOTH sides of the AC FUSE (3a/5a Glass fuse)...make sure Fuse and clips are passing fully voltage
Not recognizing that AC IS available in AUTO Mode could be issue with that Upper display board
Freezer cold...food compartment NOT
Could be circuit board not allowing FULL heating cycle
Could be gas flame NOT generating enough vapor ammonia to allow for full cooling effect (burner clean/flue clean----strong blue flame that just reaches up into bottom of flue)
BAD cooling unit......obstruction between freezer low temp evap coil and food compartment high temp evap coil (freezer cold/food NOT----CLASSIC symptom)
*****As suggested by DOUG remove heater element leads from circuit board and plug DIRECTLY in the 120VAC outlet....both compartments WILL get cold IF cooling unit is functioning properly. Then the issue is with 'controls'
If food compartment does NOT get cold...then bad cooling unit
Simple test and FrEE
