5.Rotational Sensor Assembly

The Rotational Sensor Assembly is located on the right hand side of the dryer basket (tumbler) section. It consists of a magnetic rotational switch, mounted on the bracket which is bolted to the basket (tumbler) section. A magnet is riveted to the basket (tumbler) of the dryer.

The magnetic rotational sensor switch senses the rotation of the basket (tumbler). If the gap between the sensor switch and the magnet is greater than a preset amount, then the dryer will shut down on Rotational Sensor Failure.

a. Rotational Sensor Switch Replacement

1)Discontinue electrical power to the dryer.

2)Remove the two (2) TEK screws securing the rotational sensor bracket to the basket (tumbler) section.

3)Remove the magnetic rotational sensor switch from the mounting bracket, by removing the adjustment nut.

4)Depress the tabs on the rotational sensor harness plug and pull apart, then remove the sensor switch.

5)To install a new sensor switch, connect the plug of the new sensor switch to the sensor harness.

6)Place one (1) adjustment nut onto the sensor switch and insert into the mounting bracket.

7)Place the second adjustment nut on but DO NOT tighten. The magnets on the basket (tumbler) and the sensor switch must be in a horizontal line to one another.

8)The gap between the magnet and the sensor switch must be 1/8-inch (3.175 mm).
