* Microprocessor controller (computer) "MTR" relay output indicator is off.
1. Failed microprocessor controller (computer).
F. Blower (fan/impellor) motor operates okay for a few minutes, 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 the motor.
c. Failed motor.
d. Failed impellor/fan drive bearings.
e. V-belts are too tight.
2. Failed overload protector.
G. Both drive motor and blower (impellor/fan) 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/impellor) motor fuse(s) / overload(s).
2. Failed motors (both blower [fan/impellor] and drive).
H. Both drive motor and blower (fan/impellor) motor not operating... microprocessor controller
(computer) L.E.D. (light emitting diode) motor indicator dots and the "door" L.E.D. indicator are
on but relay output L.E.D. indicators are off (microprocessor controller [computer] L.E.D. display
does not read "door")...
1. Failed microprocessor controller (computer).
I. Both drive motor and blower (impellor/fan) motor run for a few minutes then stop...
microprocessor controller (computer) L.E.D. (light emitting diode) display continues to read time
or percent of extraction and ALL indicator dots are off...
1. Fault in main door switch circuit ...
a. One (1) of the main door switches are out of adjustment.
b. Loose connection somewhere in the door switch circuit.
2. Fault in the lint drawer switch circuit.
