Testing the Electronic Control Module

To help avoid electrical shock, no live electrical test of the Electronic Control Module will be made.

Start by unplugging the unit, then remove the connector from terminals 10 and 11 of the Electronic Control Module. With this connector removed, plug the unit in, set the dry timer to 10 minutes, then push the unit’s ON button. All measurements are made with an ohmmeter.

When the test is concluded, unplug the unit before replacing the connector on terminals 10 and 11.

NOTE: With the connector replaced on terminals 10 & 11 and power applied to the unit, 115 volts AC should be present between pins 10 & 11. If test of pins 1-7 are abnormal the timer may be defective. If tests of pins 8 & 9 and 12-15 are abnormal, the motor may be defective. If all indications are correct and the motor does not run, Electronic Control Module may be defective.
