s/s both compartments warm

I that model number does not appear to be valid. We may not need it, but if you could provide the correct model number i could help us out. If they are saying the fans are running and both sides are not cooling, then your cold control should be working. You could have a defrost issue, which could be the timer, defrost thermostat, or heater, the compressor may not be running. Check for power to the compressor and if there is power you may have a bad compressor or a bad overload/relay. IF compressor and fans are running, air flow is good, and there is not a defrost issue, then you could have a refrigerant leak.
