4. The vent conduit, fan and the duct are
removed as an assembly.
Operation
Heater operation is the same as the passive
system. The fan is a brushless motor and
operated by 13.5 VDC and runs at 6,000 RPM.
There are no consistent resistance readings to
make a viable ohm check. A power dry cycle is
50 minutes, then the Clean light comes on. If the
consumer does not open the door, the fan will
run an extra 90 minutes before shutting off. If
the consumer opens the door, the fan will shut
off and not restart should the door be closed and
latched.
Diagnostics
The door will have to be removed and separated.
The door can be plugged back in and put into
service mode to make voltage checks. 12 to 14
VDC can be checked at the UI board, connector
J102 (2-pin connector) from
red
to
black
.
Venting / Airflow
To remove the vent, the door must be removed
and separated (see
Door
under the
Tub and
Structure
section of this guide).
Fan Assist Venting
(on some models)
A fan assembly is located in the door.
Components include a 13.5 VDC fan and ducting
to the bottom of the door. The power dry system
must be removed to access the door control
components. Operation, specifications and
diagnostics will be covered in the
Dry System
section of this service guide.
Power Dry System Removal
1. Remove the inner door vent cover.
2. Disconnect the wire harness from the fan to
the User Interface (UI) control.
3. Remove the 1/4-inch hex-head screw.
