B. Drive motor is not operating (does not start)...
* Microprocessor controller (computer) relay output indicator (either forward “FWD” or reverse
“REV” is on.
1. Blown drive motor contactor fuses or overloads.
2. Failed drive motor contactor.
3. Failed drive motor.
* Microprocessor controller (computer) relay output indicator (neither forward “FWD” or reverse
“REV”) is on.
1. Failed microprocessor controller (computer).
C. Drive motor operates in one direction only... stops and restarts in the same direction...
* Appropriate microprocessor controller (computer) relay output indicator is on.
1. Failed reversing contactor (relay).
2. Failed electrical reversing contactor interlock.
* Appropriate microprocessor controller (computer) relay output indicator is off.
1. Failed microprocessor controller (computer).
D. Drive motor operates okay for a few minutes and then either repeatedly or occasionally trips the
overload protector...
NOTE: When the overload protector trips, the microprocessor controller (computer) L.E.D. (light
emitting diode) display will read “door.”
1. Motor is overheating ...
a. Motor air vents clogged with lint.
b. Low voltage to motor.
c. Failed motor.
d. Tumbler (basket) is binding... check for an obstruction.
e. Tumbler bearings are binding.
f. V-belts are too tight.
g. Dryer has an oversized load.
h. Voltage to the dryer is incorrect... check dryer data label for specified voltage.
