Operation Overview
The typical dryer cycle progresses as follows:
1. A cycle is selected and the
START
button is pressed.
2. The motor(s) are activated. The drum motor rotates the drum at a speed of 47-51 RPM (revolutions per
minute) for 1 minute clockwise and 9 minutes counterclockwise. The drum motor comes to a complete
stop between direction changes. (Drum does not rotate in rack dry cycle.)
3. The heater coils (burner for gas models) are activated. The coils (burner) cycle on and off to achieve the
desired temperature throughout the heating portion of the cycle.
4. If sensor drying is selected, the heater coils (burner for gas models) are activated. The coils (burner) cycle
on and off until the load has achieved the desired dryness level.
5. If timed drying is selected, the heater coils (burner for gas models) are activated and cycle on and off for
the selected time at the selected temperature.
6. The heater coils (burner for gas models) discontinue operation after the dryness level or elapsed time has
been achieved.
7. The motor(s) continue operating until the clothes temperature drops below speci
fi
ed temperature (cool
down).
9. The display turns off.
Dryer Air Flow System
Air enters the dryer cabinet, passing through the heating coils (electric models) or the diffuser (gas models)
and into the drum. The hot air heats the wet clothes, gradually removing their moisture in the form of water
vapor. The moist air is vented through the dryer exhaust. Overall heater temperature is regulated by means
of two temperature sensors, an inlet sensor, located near the heating coils or diffuser, and an outlet sensor,
located at the blower. A safety thermostat, located on the heater pan or diffuser, and an outlet backup
thermostat, located near the blower, cycle the heating coils (burner on gas models) if temperatures are
excessive. A high limit thermostat, also located on the heater pan or diffuser, provides additional safety. If the
thermostat reaches a temperature beyond its maximum temperature rating, power will be interrupted to the
heating coils (burner on gas models) and the main control board, thereby terminating dryer operation. A rack
dry thermostat, located at the blower, cycles the heating coils (burner on gas models) if temperatures are
excessive when using the Rack Dry System
