ADC AD-310 service manual Impellor fan motor is not operating does not start

2. Failed overload protector.

E.Impellor (fan) motor is not operating (does not start)...

*Microprocessor controller (computer) “MTR” relay output indicator is on.

1.Blown blower (impellor and fan) motor fuses or overloads.

2.Failed blower (impellor and fan) motor contactor (relay).

3.Failed blower (fan and impellor) motor.

4.Sail switch verification circuit not in open position prior to the start of the drying cycle.

*Microprocessor controller (computer) “MTR” relay output indicator is off.

1.Failed microprocessor controller (computer).

F.Blower (fan and impellor) 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.Failed gear reducer or tumbler bearing.

f.V-belts are too tight.

h.Motor is running at incorrect voltage.

2.Failed overload protector.

G.Both drive motor and blower (fan and impellor) motor are not operating... microprocessor controller (computer) L.E.D. (light emitting diode) motor indicator dots and the “MTR” relay output and forward “FWD” or reverse “REV” L.E.D. indicators are on.

1.Blown drive motor and blower (fan and impellor) motor fuses or overloads.

2.Failed motors (both blower [fan and impellor] motor and drive motor).
