Error code 50 means excessive refrierator section compressor run. Possible causes include: dirty condenser, stopped condenser motor, faulty termistor or an evaporator refrigerant leak. If it is a refrigerant leak it usually shows up as frost or water driplets half way down on the back wall. Clear codes by holding the alarm button in for 15 seconds.

turn the unit off for a few minutes then back on. If you have a real problem that needs to be serviced the service and ice light will star flashing again relativly soon

Most likely you have a leak in the evaporator. Subzero warranties the parts for 12 years. Call them to find out what they will cover. They are agreat company and will be fair with you.
