2. Remove ice maker (see Access Ice Maker
Module, Motor and support section). Remove
evaporator fan cover and screws. Remove
screws securing back wall.
3. Disconnect wiring and remove back wall.
Evaporator fan is now accessible.
The freezer section evaporator fan is a 120
VAC motor and can be tested from the High
Voltage Board. (Refer to High Voltage board
access).
With the main power switch OFF, remove the
Yellow wire from E2 on the HV board. Using
an Ohm reading, Apply one lead to
the yellow wire and the other to Neutral (E9).
The resistance should be approximately
30.3 ohms.
When the fan relay is energized, Line voltage
is sent to E2 and then to the Freezer fan
motor. If voltage is present and no fan
movement, replace fan motor.
4. Reverse procedure to reinstall.
