Kegerator no longer running cold

sounds like the thermostat. can you bypass it (ie connect the two wires together) and make it run all the time? If so, replace the thermostat

Check for air flow into the fridge compartment. In these refrigerators, incoming cold air is ported in at the top left-hand side of the fridge compartment...the problem has to be with the return air vent inside the beer compartment. The return air port in a Maytag side by side refrigerator is located behind the crisper drawers in the beer compartment. Condensation can freeze in a sheet over this port blocking the return air flow, creating a warm compartment.

If the ambient temperature matches the temperature achieved through refrigeration, why would the refrigerator run? Is your beer cold?

which fan , inside or out.. if outside condensor fan is running then it has a bad 175 capacitor or if the compressor is running then it is low on refrigerant. if the cond fan is not running then check thermostat.. you can do this by connecting the two wires together.. another way to check the compressor, cond fan is to reach under and unplug the wires going to comptessor and plug into a 12ga extention cord.

If its 46 degrees that tells me compressor must be running.So what I would do first is unplug unit,locate compressor condenser coil & fan.Clean condenser coil with brush,air,or coil cleaner.plug back up wait & see.If still not cold enough needs freon.

no use a Ranco p# A12-700 make sure the capillary is in the coilto sense the temp and set it to 1.5 on the knob. any colder and it could get too cold . you may be able to set it at 2 but be careful. it is a constant cut in at 37 degrees coil temp. the box temp will drop to usually to 28 or 29 at cut out.

room is not cooling to desired temp. and fall back to 82
even I set it for 72.

Sounds like the fan can be running backwards. I'm not sure of you exact model, but it has to match the air flow of the original unit. Do you remember? Some manufacturers use reversable motors and are some what easy to reverse.

Good luck and hope this helps.

It can take a very long time to get a keg of beer down in temperature. The heat transfer from a keg is slow due to the lack of air circulation inside the keg. You should also check your condenser coils, make sure they are clean. Door gasket should also be in good repair. Hope this helps.

electrician do one thing, electricity. If the unit cools, the compressor is running. a power outage should not put the compressor in a "Weaken" state. I would check the starting components. don't overlook your surge protector causing a voltage drop. try running the unit without the protector.
let me know if I can be of any further help.
