Operation Overview - GE DCVH480EK Technical Service Manual

Air enters the dryer cabinet, passing through the heating elements 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 an inlet temperature thermostat,
located on top of the heater assembly, and an outlet thermistor, located at the blower. A safety thermostat,
located on top of the heater assembly, and an outlet thermostat, located near the blower, cycle the heating
elements if temperatures are excessive. If the thermostat reaches a temperature beyond its maximum
temperature rating, power will be interrupted to the heating elements and the control board, thereby
terminating dryer operation.

The typical dryer cycle progresses as follows:
1. A cycle is selected and the START/PAUSE button is pressed.
2. The motor is activated. The drum motor rotates the drum at a speed of approximately 50 RPM
(revolutions per minute).
3. The heater elements are activated. The elements cycle on and off to achieve the desired temperature
throughout the heating portion of the cycle.
4. If sensor drying is selected, the heater elements are activated. The elements cycle on and off until the
load has achieved the desired dryness level.
5. If timed drying is selected, the heater elements are activated and cycle on and off for the selected time at
the selected temperature.
6. The heater coils discontinue operation after the dryness level or elapsed time has been achieved.
7. The motor continues operating until the clothes temperature drops below specifi ed temperature (cool
down).
9. The display turns off.
