hood. Verify that moisture
sensor connector (P1)
on board is secure.
Short out sensor bars in
cylinder and verify zero
Ohms at P1. Clean sensor
bars.
Remove front panel and
verify that connectors to
the moisture sensor are
secure.
Refer to paragraph 96.
NO
Verify that if drying rack is being used,
TIMER is set on TIME DRY.
