Component Testing
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all earthing wires are connected before certifying unit as repaired and/or operational.
Component Description
Overload / Relay When voltage is connected and relay is
cool, current passes through relay to start
winding.
After a short time, current heats the
resistor in relay and resistance will rise
blocking current flow through relay.
Start winding remains in the circuit through
run capacitor.
Solid state relay plugs directly on
compressor start and run terminals. Relay
terminals 2 and 3 are connected within
relay. Run capacitor is connected to relay
terminal 3. L2 side of 120 VAC power is
connected to relay terminal 2.
Control board On some models.
See "Control Board" section for
troubleshooting information.
Ice maker Optional on some models.
See "Ice Maker" section for service
information.
Evaporator fan Evaporator fan moves air across
motor evaporator coil and throughout refrigerator
cabinet.
Electric damper Damper control balances the air delivery
control between refrigerator and freezer
compartments providing temperature
control for refrigerator.
Electrical voltage activates damper control
and door closes restricting flow of air from
freezer compartment to refrigerator
compartment.

WARNING
Test Procedures
1. Disconnect power to the refrigerator.
2. Remove relay cover and disconnect leads.
3. Check resistance across terminals 2 and 3 with an ohmmeter:
Normal = 3 to 12 ohms
Shorted = 0 ohms
Open = infinite ohms
1. Disconnect power to unit.
2. Disconnect fan motor leads.
3. Check resistance from ground connection solder. Trace to motor frame must
not exceed .05 ohms.
4. Check for voltage at connector to motor with unit in refrigeration mode and
compressor operating.
Check resistance across terminals.
If no resistance across terminals replace damper control.
