The customer called and reported this unit is not cooling. Upon arrival, I see all of the display lights flashing, the ice door is opening and shuting every few seconds, and there is a clicking sound coming from the display board. The compressor is running, as is the condensor fan; however, the evaporator fan is not running. I measured 6.34 VDC at the fan. I believe the low voltage board at the display is
bad, but I I'm wondering why the fan was not turning. If it is receiving 6+ volts, wouldn't it turn slowly? How can I test the motor to confirm it is still good?
