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.
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
1/8-inch (5.71 cm).
9) Tighten the adjustment nuts installed in
Step #7 and Step #6.
10) Reestablish electrical service to the dryer.
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.
