Evaporator Fan
FUNCTION
Circulates air across the evaporator and throughout the
cabinet interior.
SPECIFICATIONS
120/60/1 .38 amp
220V, 50/60, 1
CHECK PROCEDURE
1. Use an extendable mirror and fl ashlight to verify fan
blade rotation.
2. Isolate suspect motor by disconnecting the wiring
connectors.
3. Check continuity across the terminals with an ohm
meter.
• Resistance = Motor is good
• Open (OL) = Replace motor
Condenser Fan
FUNCTION
Moves air across the condenser fi ns to provide heat
transfer from the condenser coil to the air stream.
This warm air is used to evaporate any evaporator
condensate from the drain pan.
SPECIFICATIONS
CHECK PROCEDURE
1. Isolate by disconnecting the wiring connectors.
2. Check continuity across the terminals with an ohm
meter.
• Resistance = Motor is good
• Open (OL) = Replace motor
Ice Bin Lid Microswitch
FUNCTION
Prevents operation of machine with ice bin lid removed.
Two micro switches are used, one micro switch signals
the control board to initiate a failure screen and the
second micro switch prevents the shaver motor from
running.
SPECIFICATIONS
Shaver Motor Switch - Inner switch
Control Board Input Switch - Outer switch
Normally Open, Single Throw
CHECK PROCEDURE
NOTE: Use a volt/ohm meter to check switch operation.
1. Inspect switch for correct wiring.
2. Isolate the switch by disconnecting the wiring
connectors.
3. Check continuity across the switch terminals and
refer to correct chart for switch.
