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 User Interface (UI)
board, connector J402 (2-pin connector) from red
to black.
