c) Lint Drawer Closed circuit branch ...
The lint drawer closed switch is located in the front of the dryer. When the lint drawer is closed,
it closes the switch contacts, powering the lint drawer closed relay. Then, the dry enable relay
will close, supplying 24 VAC to the Phase 5 microprocessor (computer) door signal. This sequence
will occur only if the following conditions are met;
(1) Blower (impellor and fan) Motor Overload is not tripped.
(2) Drive (tumbler and basket) Motor Overload is not tripped.
(3) Doors are closed.
(4) Lint Drawer is closed.
(5) Dryer is level.
6) Phase 5 Microprocessor Controller (computer)
The Phase 5 microprocessor controller (computer) is powered by 240 VAC on pins #7 and #13. A
jumper wire on pins #1 to #11 is required to configure the transformer for 240 VAC. The temperature
sensor probe is a bullet shaped device that is located above the lint basket. This temperature probe is
used to sense the temperature in the exhaust of the dryer. The temperature sensor is a two (2)
terminal monolithic integrated circuit temperature transducer that provides an output current proportional
to absolute temperature. The transducer acts as a high impedance temperature dependant current
source of 1mA/ºK.
