11)Replace ALL the wires removed in Step #5 (refer to previous page [page 91]).
12)Mount the top of the thermal magnetic starter to the top of the din rail and press down and in. Inspect ALL of the work performed.
13)Set the control of the thermal magnetic starter to the "start" position.
14)Reestablish electrical power to the dryer.
7.Rotational Sensor Assembly
The Rotational Sensor Assembly is located on the right rear drive wheel. It consists of a magnetic rotational switch, mounted on the bracket which is bolted to the pillow block bearing. A magnet is riveted to the drive wheel.
The magnetic rotational sensor switch senses the rotation of the tumbler (basket). If the gap between the sensor switch and the magnet is greater than a preset amount, then the dryer will shut down on "SEFL" ("rotational sensor failure").
a)Rotational Sensor Switch Replacement
1)Discontinue electric service to the dryer.
2)Remove the adjustment nut closest to the drive wheel.
3)Remove the magnetic rotational sensor switch from the mounting bracket.
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 magnet on the drive wheel 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
9) Tighten the adjustment nuts installed in Step #7 and Step #6.
10) Reestablish electrical service to the dryer.
