D. Main Door Switch

D. Main Door Switch

The main door switch is located behind the main door on the right hand side. When the main door is opened, the switch will also open preventing the dryer from operating. The main door switch is a safety device and should never be disabled.

E. Lint Coop

The lint coop is the bottom portion of the dryer behind the lint door. Inside the lint coop is the lint screen which prevents lint from entering the exhaust system. The lint screen should be kept clean at all times. On the WDA- 385/ADG-385 models there are two (2) lint screens. The lint screens should be cleaned on a daily basis. Lint screens with tears or holes should be replaced immediately.

F. Tumbler

The tumbler consists of three or four ribs and a perforated basket along with a front and back which are riveted or screwed together as an assembly. The tumbler also consists of tie rods which support the tumbler from front to back. The tumbler support is used to mate the tumbler to the drive system in the rear. Some models also have a felt band which helps to keep lint from accumulating behind the basket.

IndicatorsNOTE If the dryer is started the L.E.D. display indicator dots are on and there are no outputs heat and/or motor output L.E.D.s are off and the dOOr input L.E.D. is on, the fault is in the Phase 5 coin microprocessor controller computer itself. If the failure was elsewhere i.e., dryers door switch circuit the L.E.D. display would read dOOr if a keyboard entry was attempted. If the L.E.D. display indicators are on and the door L.E.D. input and motor/heat output L.E.D.s are on and the motor and/or heat is not active ON, then the problem is not the door switch circuit or the Phase 5 coin microprocessor controller the problem is else where in the dryer B.
