DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit
breaker tripped? Time delay fuse?
Is dryer vent properly installed and clear of
lint or obstructions?
All tests/checks should be made with a
VOM (volt-ohm-milliammeter) or DVM
(digital-voltmeter) having a sensitivity of
20,000 ohms per volt DC or greater.
Check all connections before replacing
components. Look for broken or loose
wires, failed terminals, or wires not pressed
into connectors far enough.
A potential cause of a control not function-
ing is corrosion on connections. Observe
connections and check for continuity with
an ohmmeter.
Connectors: Look at top of connector.
Check for broken or loose wires. Check
for wires not pressed into connector far
enough to engage metal barbs.
Resistance checks must be made with dry-
er unplugged or power disconnected.

IMPORTANT
Electrostatic Discharge (ESD)
Sensitive Electronics
ESD problems are present everywhere.
ESD may damage or weaken the machine
control electronics. The new control assem-
bly may appear to work well after repair is
finished, but failure may occur at a later
date due to ESD stress.
Use an anti-static wrist strap. Connect wrist
strap to green ground connection point or
unpainted metal in the appliance.
-OR-
Touch your finger repeatedly to a green
ground connection point or unpainted
metal in the appliance.
Before removing the part from its pack-
age, touch the anti-static bag to a green
ground connection point or unpainted
metal in the appliance.
Avoid touching electronic parts or ter-
minal contacts; handle machine control
electronics by edges only.
When repackaging failed machine con-
trol electronics in anti-static bag, observe
above instructions.
