85. SYMPTOM: "oP" APPEARS IN TIME DISPLAY

Unplug power cord, remove front
panel and check for broken, loose
or incorrect wiring between
thermistor and control.
Wiring between terminals "P5"
and "P6" on control and the
thermistor terminals okay?
Remove wires from thermistor
and take resistance reading
across the thermistor terminals.
Did you read infinite Ohms?
Was temperature near thermistor
below 30°F? For safety purposes,
the control will go into the "oP"
condition if the temperature near
the thermistor falls below 30° F.
Reconnect wires to thermistor
and plug in power cord. Press
REGULAR and GO pads to start
dryer. The dryer will heat for three
minutes to raise the temperature
above 30° F.
Did "oP" appear in display after
three minutes.
