Sub Zero fridge/freezer repair diagnosis problem HELP!?

I have a sub zero 642 refrigerator that is acting up. The freezer’s temp. varies from 5 degrees to -17 degrees even though I have it set for 0 degrees. The freezer’s compressor seems to run continuously. Also, the unit in the freezer that gets cold (condensor?) seems to ice up and stay that way. The fan motor is working in the freezer and frigde. Can someone point me in the right direction. I would really appreciate it, since I sprung for the big bucks to buy it Ive been broke.The unit was made in 2000.

    YOUR EVAPORATOR IS NOT BEING DEFROSTED AND THE TEMP RISES WHEN IT ICES UP. LIKELY A STICKING TIMER BUT COULD BE A SENSOR STICKING. IF IT WERE HEATER IT WOULD NOT DEFROST ANYTIME UNTIL THE HEATER WERE REPLACED

    Make sure you vaccuum out all the intake areas often! I have a sub zero and this has always worked.

    I think you have an electronic panel that is acting up. You might find better information at -
