Fault Code 7
Motor Current Excessive.
Remedy:
(1) Free up the dryer. Remove overload or cause of jamming.
(2) Replace the motor control module.
(3) Replace the motor.
Fault Code 8
Exhaust Sensor Over Temperature.
The exhaust sensor measures over temperature (fire detection, element short
circuit or low resistance).
Remedy:
(1) Check the integrity of the sensor circuit checking particularly
for short circuits. Approximate resistances (+10%) at various
temperatures are; 32°F (0°C) = 33 KOhms, 72°F (22°C) =
11 KOhms, 104°F (40°C) = 5 KOhms. Replace thermistor
and harness if out of range.
(2) Check the element integrity in that it switches off when the
dryer is stopped.
(3) Replace the motor control module.
(4) Replace the sensor module.
Fault Code 9
Exhaust Sensor Under Temperature.
The exhaust sensor measures under temperature (open circuit or not plugged
in).
Remedy:
Refer to steps for over temperature fault (fault code 8) above, but
open circuit likely.
