Vent Wax Motor - Sears Elite 665.12762K310 Manual

TESTING
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.

Vent Wax Motor

This test will check the wiring to the vent and the vent wax
motor itself. The following items are part of the vent wax
motor circuit.
■ Harness/Connection
■ Vent Wax Motor
■ Control Board
NOTES:
Only dishwashers with the SmartDry™ option have a vent and
fan. If moisture is detected between outer and inner door
panels or on cabinets around air inlet located on side of door
panel, check that the vent damper is closing properly using the
Service Diagnostic Cycle.
Also verify that wax motor seal and vent bezel seal are not
pinched or missing. Verify there are no leaks around the vent
bezel seal allowing moisture past the bezel and into the door
panel area.

Test Procedure
1. Unplug dishwasher or disconnect power.
2. Remove outer door panel to access control board.
3. Unplug connector P10 from control board.
4. Check the vent wax motor and harness—using an
ohmmeter, measure the resistance between P10-1 and
P10-3.
¾ If the resistance is between 600-1800 ohms, the wax
motor and harness are good. Go to step 5.
¾ If outside the range, replace the vent wax motor.
¾ If an open circuit is detected, check connections and
harness continuity between control and vent wax
motor. If good, replace the wax motor.
5. Reconnect P10 to control board.
6. Plug in dishwasher or reconnect power.
7. Check for AC voltage from the Control. Start the
Diagnostic Cycle and measure for AC out of the control
between P10-1 to P10-3 using a voltmeter set to AC.
NOTE: During the Diagnostic Cycle, the vent wax motor is
always energized.
¾ If no AC voltage is measured, replace the control board
and retest.
¾ If 120V AC is measured and dispenser motor is
energized, go to step 8.
8. Unplug dishwasher or disconnect power.
9. Reassemble all parts and panels.
10. Plug in dishwasher or reconnect power.
