2. “HEAT” Output light emitting diode (L.E.D.) Indicator
a. If the dryer is started and there is no heat, yet the Phase 5 Dual Microprocessor Controller (DMC)
computer display heat circuit indicator dot is on, but the “HEAT” output L.E.D. indicator is off, then the
fault is in the Phase 5 DMC computer itself. If both the heat indicator dot and the “HEAT” output
L.E.D. indicator dots are on, then the problem is elsewhere (i.e., external of the Phase 5 DMC computer).
3. “MOTOR” Output L.E.D. Indicator
a. If the dryer is started and the motor is not operating, yet the Phase 5 DMC computer display motor
circuit indicator dot and “dOOr” input L.E.D. indicator are on, but the motor output L.E.D. indicator is
off; then the fault is in the Phase 5 DMC computer itself. If the motor is not operating and the
“MOTOR” output L.E.D. indicator is on, then the problem is elsewhere (i.e., external of the Phase 5
DMC computer).
