e. Failed 24 VAC step down transformer.
2. Dual Microprocessor Controller (DMC) “door” input light emitting diode (L.E.D.) is on ...
a. Failed DMC computer.
H. The dryer does not start (COIN MODELS ONLY) ... coin(s) inserted and the L.E.D. display
continues to read “FILL” and/or “Amount To Start” (does not read “PUSH”)...
1. Coin acceptor is not adjusted properly (housing is not flush with panel) or is dirty with lint.
2. Failed coin acceptor optic switch.
3. Parameter in Program Location 01 (PL01) set incorrectly ...
a. Faulty coin program should be set for “bCrS” and not “bCLO.”
I. DMC computer L.E.D. display reads “dSFL”...
1. L.E.D. display consistently reads “dSFL” and will not clear ...
a. DMC computer 1/8-Amp (Slo Blo) fuse is blown.
b. Failed DMC computer temperature sensor.
c. Broken wire and/or termination in sensor harness somewhere between the sensor bracket and the DMC
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 DMC 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 DMC
computer.
b. Failed DMC computer temperature sensor.
J. DMC computer L.E.D. display reads “Hot”...
The “Hot” display condition indicates a possible overheating condition. The DMC computer monitors the
temperature in the dryer at ALL times. If the DMC computer detects that the temperature in the dryer has
exceeded 170º F (77º 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 170º F (77º C) or lower and the DMC computer
is manually reset by closing and opening the Program Switch (PS).
