PT
2. Microprocessor controller (computer) indicator is off (and the light emitting diode [L.E.D.] display does
not read “door”) ...
a. Failed microprocessor controller (computer).
C. The dryer will not stop, even with no cycle (L.E.D. display reads “FILL”) in progress...
1. Failed motor contactor/relay.
D. The dryer operates for a few minutes, and with the microprocessor controller (computer)
motor L.E.D. indicator dot on the motor stops, and then after a period of time restarts on it’s
own...
1. Motor is overheating and tripping out on its internal overload ...
a. Motor air vents clogged with lint.
b. Low voltage to motor.
E. The dryer operates for a few minutes and then stops...microprocessor controller (computer)
L.E.D. display continues to read cycle in progress, indicator dots are off and dryer can be
restarted by pressing selection key...
1. Intermittent connection in main door circuit.
F. Microprocessor controller (computer) L.E.D. display reads “dSFL”...
1. L.E.D. display consistently reads “dSFL” and will not clear ...
a. Microprocessor controller (computer) 1/8-Amp (slo blo) fuse is blown.
b. Failed microprocessor controller (computer) temperature sensor.
c. Broken wire and/or termination in sensor harness somewhere between the sensor bracket and the
microprocessor controller (computer).
d. Failed microprocessor controller (computer).
2. L.E.D. display reads “dSFL” for a short period of time (30-seconds or less) and then returns to the normal
“FILL” mode...
NOTE: Once the microprocessor controller (computer) detects a problem, it updates every
30-seconds so that if a problem was a loose connection in this circuit which corrected
itself, the “dSFL” display condition would automatically be cancelled.
a. Loose wire and/or termination in sensor harness somewhere between the sensor bracket and the
microprocessor controller (computer).
b. Failed microprocessor controller (computer) temperature sensor.
