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 its 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.
G.
Microprocessor controller (computer) light emitting diode (L.E.D.) display reads “Hot”...
The “Hot” display condition indicates a possible overheating condition. The microprocessor controller (computer)
monitors the temperature in the dryer at ALL times. If the microprocessor detects that the temperature in the
dryer has exceeded 220º F (104º C), it will disable ALL of the dryer outputs (shut the dryer down), the buzzer
(tone) will sound for approximately 5-seconds, and the L.E.D. display will read “Hot.” The L.E.D. display will
continue to read “Hot” until the temperature has dropped to 220º F (104º C) or lower and the microprocessor
controller (computer) is manually reset by closing and opening the Program Switch (PS).
Possible reasons for overheating...
1. Restriction in location exhaust ductwork...
a. Dryer exhaust damper stuck in closed position.
b. Undersized exhaust ductwork.
2. Insufficient make-up air.
