170°F (77° C) or lower and the Phase 5 DMC (computer is manually reset by closing and
opening the Program Switch (PS).
B. L.E.D. Display Indicators (DOT)
The L.E.D. indicator dots located at the top portion of the display (refer to the illustration on page 61) indicate
the various microprocessor controller (computer) output functions while a cycle is in progress. These dots do
not necessarily mean that the outputs are functioning. They are only indicating that the function (output) should
be on.
1. Heat Circuit Indicator - This indicator dot is on whenever the Phase 5 DMC (computer) is calling
for the heating circuit to be on.
2. Motor Circuit Indicator - This indicator dot is on whenever a cycle is in progress.
C. Phase 5 DMC (Computer) Relay Output L.E.D. INDICATORS
There are six (6) L.E.D. indicators (red lights) located on the back side area of the Phase 5 DMC computer
(refer to illustration on page 68) which are identified or labeled U (upper) and L (lower) for the appropriate
circuit (i.e. door, motor, or heat). These L.E.D.'s indicate that the outputs of the Phase 5 DMC (computer), or in
the case of the door or lint drawer circuit, the inputs are functioning.
1. "DOOR" L.E.D. Indicators
a. Should be on at all times (even if dryer is not running) unless the main door or lint drawer is
open or there is a problem (open circuit) in either of these circuits.
NOTE: If the dryer is started (the display L.E.D. indicator dots are on) and there are no outputs (heat
or motor output L.E.D.'s are off) and the appropriate "DOOR" input L.E.D. is on, the fault is in
the
Phase 5 DMC computer itself.
NOTE: If the failure was elsewhere (i.e. dryers' door or lint drawer circuit) the display would read "door"
if a keyboard entry was attempted. If the display L.E.D. indicators are on, and the door L.E.D.
input and motor and heat output L.E.D.'s are on and yet the motor or heat is not on; then the
problem is not the door switch or the
Phase 5 DMC (computer), the problem is elsewhere in
the dryer.
2. "HEAT" Output L.E.D. Indicator
a. If the dryer is started and there is no heat, yet the
Phase 5 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 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]).
