G. The dryer does not start (for COIN MODELS ONLY)...coin(s) inserted and the light emitting
diode (L.E.D.) display continues to read “FILL” and/or “Amount To Start” (does not read
“PUSH”)...
1. Coin acceptor is not adjusted properly or is dirty with lint.
2. Failed coin acceptor switch.
3. Parameter in Program Location 01 (PL01) set incorrectly.
a. Bad coin program should be set for “bCrS” and not “bCLO.”
H. 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
stop “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 canceled.
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.
I. Microprocessor controller (computer) 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 controller (computer) 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).
