Clean the condenser coil, a clogged condenser coil will cause to much heat load on the condenser and compressor and it will run non-stop.

The factory recommends that you clean your condenser coil underneath your refrigerator every 6-12 months, if you have pets that shed hair, then every 3-6 months.

condenser coil is very clean, I don't think that's the problem.

When it runs for 2-4 hours is the compressor very hot?

Customer: replied 14 days ago.
No the compressor is warm but not hot. Fan runs fine too.

At the end of the day when it's been not running for 8 hours the temperature settings on the outside still show -8 and 34. After you unplug and plug it back in they show the current temperature which is usually something like 24 and 48 by then. But then it cools all the way down to where it should be and stops.

Unfortunately this means the main control will need to be replaced.

Then that means the User Interface is faulty which is not available for that unit.

Expert:  Jamie_2013 replied 14 days ago.

The part number for that in case you could find a used one is DA41-00225A
