c)Dryer Level Switches circuit branch...

(1)On 1-Way Tilt models, this switch is in series with the dry enable.

(2)On 2-Way Tilt models...one (1) pole of each of the two (2) level switches (LS1-A and LS2- A) are in series with the dryer level relay and the other pole is in series with the opposite piston. IF THE OPPOSITE SIDE IS NOT LEVEL, THE DRYER WILL NOT TILT.

d)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 TSX 07 PLC. When the lint drawer is closed, the lint drawer L.E.D. (light emitting diode) is on.

b.Phase 7 Microprocessor Controller (computer)

1)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 dependent current source of 1mA/ºK. The typical accuracy of this probe is +/- 1.5º C (+/- 2.7º F). In a case where the temperature reaches 220º F (104º C), the Phase 7 microprocessor

(computer) will shut down and the L.E.D. (light emitting diode) will display “Exhaust High Temp Fault.” To restart a cycle the “CLEAR/STOP” button must first be pressed.

To check a temp sensor you first need a DMM (Digital Multimeter) with a diode check position. Put the meter on diode check, place the red lead of the meter on the black lead of the temp sensor and the black lead of the meter on the white temp. sensor wire. At this point you should get no response from meter (infinite). If you get a reading the temp sensor is defective.
