C. PHASE 5 MICROPROCESSOR CONTROLLER (COMPUTER) RELAY
OUTPUT LIGHT EMITTING DIODE (L.E.D.) INDICATORS
There are three (3) L.E.D. indicators (“red” lights) located at the lower back side area of the microprocessor
controller (computer) which are identified/labeled as “DOOR,” “HEAT,” and “MTR” (motor). These L.E.D.s
indicate that the outputs of the microprocessor controller (computer), or in the case of the door switch, the inputs
are functioning.
1. “DOOR” - L.E.D. SHOULD BE ON ALL THE TIME (even if the dryer is not running) unless the
main door is open or there is a problem (open circuit) in the main door switch circuit.
NOTE: If the dryer is started (the display L.E.D. indicator dots are on) and there are no outputs
(“HEAT” and/or “MTR” output L.E.D. are off) and the “DOOR” input L.E.D. is on, the fault is
in the Phase 5 microprocessor controller (computer) itself.
