Component Testing; Dishwasher Components - KitchenAid KUDD03DT Series 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.
FAN MOTOR
Refer to page 4-13 for procedure for servicing
the fan motor.
1. Unplug dishwasher or disconnect power.
2. Disconnect the wire connectors from the
FAN MOTOR terminals on fan motor.
3. Set the ohmmeter to the R x 1 scale.
4. Touch the ohmmeter test leads to fan mo-
tor terminals. The meter should indicate
approximately 79 Ω.

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.
• Voltage checks must be made with all con-
nectors attached to the boards.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
