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.

2. Failed overload protector...

a. Incorrect overload setting.

E. Blower (squirrel cage fan) motor is not operating (does not start)...

*Microprocessor controller (computer) input/output (I/O) board “FAN” relay output indicator is

on.

1. Blown blower (squirrel cage fan) motor overloads.

2. Failed blower (squirrel cage fan) motor contactor (relay).

3. Failed blower (squirrel cage fan) motor.

4. No 24 VAC present at fan motor contactor coil.

*Microprocessor controller (computer) I/O board “FAN” relay output indicator is off.

1. Failed microprocessor controller (computer) I/O board.

F. Blower (squirrel cage fan) 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) I/O board

“red” light emitting diode (L.E.D.) “FNOL” will be off and the display will read “Fan

Overload Fault.”

1. Motor is overheating...

a. Motor air vents clogged with lint.

b. Low voltage to motor.

c. Failed motor.

d. Basket (tumbler) is binding...check for an obstruction.

e. Failed gear (speed) reducer or basket (tumbler) bearing.

f. V-belts are too tight.

g. Motor is running at incorrect voltage.
