than 256
milliseconds
Check for:
- Loose or open wire
terminals in Door
Sense circuit.

Possible motor
transistor error
If either
motor
transistor is
seen open or
shorted
during
startup
Check for:
-
Loose
connections in
motor circuit.
-
Run System
Check Mode
and check the

sensed to be
pressed
more than
75 seconds,
the key shall
be assumed
to be stuck.

and
Signal (+)
keys for 3 seconds, will put the dryer into the
System Check mode and "
SC
" will display. The
following table lists the various functions based on the
keys being pressed.
