Component Testing; Pressure Switch - KitchenAid Pro Line KHWV01RSS Technical Education

Before testing any of the components, perform
the following checks:
• Control failure can be the result of corrosion
on connectors. Therefore, disconnecting and
reconnecting wires will be necessary through-
out test procedures.
• All tests/checks should be made with a VOM
(volt-ohm-milliammeter) or DVM (digital-volt-
meter) 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.

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 power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
• Unless stated otherwise, make all resistance
checks by disconnecting the component con-
nector at the Central Control Unit (CCU).
WARNING
2. Disconnect the hose and wire connector
from the pressure switch.
3. Set the ohmmeter to the R X 1 scale.
4. Touch the ohmmeter test leads to the pres-
sure switch connector pins shown below.
The meter should indicate 0 Ω for each
measurement.
