"C" VERSION ELECTRONIC DRYER CONTROL

There is no reliable electrical check that can be made on the electronic control board. Do not attempt

to replace any components on the electronic control board. The following tests will isolate problems

with the electronic control board and other related components. (Fig. 48)

NOTE: Check all wiring and connections and perform the following tests before attempting to

replace the electronic control board.

Timer Shuts Off but Clothes are Still Damp

1. Moisture Sensor -

a. Check for continuity between the Yellow/Red wire and chassis ground.

•

If there are no wet clothes touching the sensor, there should be NO

CONTINUITY (infinity).

•

If there are wet clothes touching the sensor, There should be CONTINUITY.

b. If either of these readings are NOT CORRECT, replace the moisture sensor.

2. Timer Switch 0 -

a. This switch should read OPEN except at the end of a moisture sensing cycle.

b. If the switch reads CLOSE, replace the timer.

3. Electronic Control Board - If the moisture sensor checks GOOD and Timer Switch 0 check

GOOD, replace the electronic control board.

Timer Does Not Advance but Clothes are Dry

Check to see if the timer advances in a timed cycle.

1. If timer does NOT advance in a timed cycle: Check the timer motor for continuity (1800-

2900 ). If this reading is NOT correct, replace the timer motor.

2. If the timer DOES advance in a timed cycle but not in a moisture sensing cycle:

a. Check the moisture sensor. Check for continuity between the Yellow/Red wire and

chassis ground.

•

If there are no wet clothes touching the sensor, there should be NO

CONTINUITY (infinity).

•

If there are wet clothes touching the sensor, There should be CONTINUITY.

b. If either of these readings are NOT CORRECT, replace the moisture sensor.

c. If the moisture sensor checks GOOD, replace the electronic control board.
