6.3.1 Steps for troubleshooting G-series Evaporator Fan

1. First verify fan icon is illuminated on the display indicating a call for the evaporator fan. (Remember the
fan will shut off when door is opened so if you want to open the door to physically check to see if fan is
running you will need to disconnect white door switch connector from control board.)
2. Next use an amp meter to prove the evaporator fan motor is running.
3. If fan motor is not running use voltage meter to measure the voltage at fan motor if measurement
within +- 10% of rated voltage replace the fan motor
