Component Testing; Door Sensor - KitchenAid Pro Line KHEV01RSS 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
throughout 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.

DOOR SENSOR

Refer to page 4-2 for the procedure for access-
ing the door sensor.
The door sensor is a normally-open reed switch
that is activated (closed) by a magnetic field.
To test the switch:
1. Unplug dryer or disconnect power.
2. Turn off gas supply to dryer.
3. On the back of the front panel, disconnect
the door sensor plug from its connector.
4. Set the ohmmeter to the R X 1 scale.
5. Open the dryer door.

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.
WARNING
6. Touch the ohmmeter test leads to the door
sensor plug pins. The meter should indicate
an open circuit (infinite).
7. Close the dryer door, and the meter should
indicate continuity (0 Ω).
