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? Was a regular fuse used? Use a time-
delay fuse.
■
Is dryer vent properly installed and clear of lint
or other obstructions?
■
All tests/checks should be made with
a VOM (volt-ohm-milliammeter) or DVM
(digital-voltmeter) having a sensitivity
of 20,000 Ω 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 functioning 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 dryer
unplugged or power disconnected.
DIAGNOSTIC TESTS
These tests allow factory or service personnel
to test and verify all inputs to the machine control
electronics. You may want to do a quick and
overall checkup of the dryer with these tests
before going to specific troubleshooting tests.
