1. Thermal Fuse
2. Exhaust Thermistor
3. High temp cutout
4. High temp thermostat
5. Motor Switch 1M to 2M
6. Gas Valve Coils
Using this same theory we can show that
if there is line voltage showing at the 2-pin
connector for the gas valve, then all of the
thermal components are closed and OK! We
would also know that the motor switch 1M
to 2M is closed as well, because the neutral
side of line voltage must pass through this
motor switch that is only closed if the motor is
running.
With Electric heat models, as with gas heat
models, when the motor reaches full speed
and the centrifugal switch trips, the switches
change state, although with electric heat
models full line voltage (208-240volts) is
supplied to the heating element when the
motor switch M1 to M2 is closed.
When WHITES AND COLORS is selected,
the high heat cycle is activated. The high temp
cycle uses the circuit that involves the 155°F
setting of the exhaust thermistor.
When the cycle type is selected on PD models
the dryer motor circuit is energized. The motor
has power sent to both the Run and the Start
windings. When the motor reaches run speed
the centrifugal switch snaps closed and the
switches in the motor switch change position.
Motor switch 5M continues to power the main
motor winding but the switch contact to the
Start winding is opened, which drops the start
winding out of the circuit. At the same time
motor switch 1M closes to motor switch 2M
which allows the circuit to close, completing
the heater circuit. Now the blower, the drum,
and the heat are all working.
Notice the components in this gas heat circuit;
heat can be shut off by opening any of the in-
line components:
