5. "DOOR" LED Indicator -

The indicator should be on all the time (even if the dryer is not returning) unless the main door or lint

drawer is open or there is a problem (open circuit in the main door or lint drawer circuit).

NOTE: If the dryer is started (LED display indicator dots are on) and there are no outputs

(heat and/or motor output LEDs are off) and the "dOOr" input LED is on, the fault

is in the Phase 5 OPL microprocessor controller itself. If the failure was elsewhere

(i.e., dryer's door switch circuit) the LED display would read "dOOr" if a keyboard

entry was attempted. If the LED display indicators are on the door LED input and

motor/heat output LED's are on and the motor and/or heat is not active (on), then the

problem is not the door switch circuit or the Phase 5 OPL microprocessor controller

and is elsewhere in the dryer.
