Component Testing - KitchenAid KUWS24RSBS Technical Education

Before testing any of the components, perform
the following checks:
• The most common cause for control failure
is corrosion on connectors. Therefore, dis-
connecting and reconnecting wires will be
necessary throughout test procedures.
All tests/checks should be made with a VOM
•
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
EVAPORATOR FAN mOTOR
1. See Page 4-5 for access and removal proce-
dures for the evaporator fan and motor.
2. Touch the leads of an ohmmeter to the termi-
nals of the evaporator fan motor.
3. The meter should indicate 150 ohms + 10%

COmPONENT TESTING

Electrical Shock Hazard
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Resistance checks must be made with pow-
er cord unplugged from outlet, and with wir-
ing harness or connectors disconnected.
DEFROST HEATER
1. See Page 4-10 for access and removal pro-
cedures for the Defrost heater.
2. Touch the leads of an ohmmeter to the termi-
nals of the Defrost Heater. The meter should
indicate 150 ohms + 10%
