Caution:
Please read our safety
information before attempting any testing, maintenance
or repairs.
Before testing the start switch, unplug the dryer or shut
off the power at the fuse box or breaker panel to avoid an
electrical shock hazard.
The start switch is located
inside the control console. Remove the screws on the side
or lower front (they may be hidden under trim pieces that
will have to be removed first). Place a towel on top of the
dryer to protect the finish. Tilt the control console forward
onto the towel and remove the rear panel.
Locate the start switch, it
will have two or three wires connected to it.Label the wires and connections
so that you can properly reconnect them later. The wires are connected with slip
on connectors. Firmly pull the connectors off of the terminals (do not pull on
the wire itself). You may need to use a pair of needle-nose pliers to remove the
connectors. Inspect the connectors and the terminals for corrosion. If either
is corroded they should be cleaned or replaced.
Use a continuity tester or multitester
to
test for continuity.
Set the multitester to the ohms setting X1.
For a two wire switch, touch one probe to each terminal. You
should get a reading of infinity. With the probes still in
place, press and hold the start switch, the reading should
change to zero.
For a three wire switch, touch
one probe to the terminal labeled NC (or CT1) and touch the
other probe to the terminal labeled CO (or R1). You should
get a reading of infinity. With the probes still in place,
press and hold the start switch, the reading should change
to zero.
If the switch fails either test,
it should be replaced.
