2.Some cooling
•Clean condenser.
•Check condenser fan.•Possible system leak.3.No cooling
•Check compressor/fan operation•Check refrigeration system pressure•Check wiring and power at circuit board4.Noise
•This is a frost free unit with two fans, compressor, and two solenoid valves. Some noise is normal such as a hum from the fans/compressor. Also, during an ice harvest it is normal to hear water fill- ing the mold and cubes dropping in the bucket.
5.Condensation on mullion

•Frost may be visible through the evaporator cover slots.•Any buildup on the bottom of the liner could be caused by failure to clean up spilled ice cubes.
•If evaporator is not defrosting, the board can be manually entered into a defrost cycle using the diagnostic feature.
•If evaporator or drain pan does not clear during a defrost, check the bypass valve coil for continuity.
•Drawers not closing properly.7.Display not operational
•Check four conductor wires from main board to display board. The display board should have red light and flashing green light on the rear of the board. If these lights are not lit, the wire is not con- necting to the main board.
8.Dot flashing on display
•If a thermistor goes out of range it will illuminate a dot on the display board. This dot will remain lit even if the thermistor goes back into range. It can be cleared by switching the unit off and back on.
