DRYER TROUBLESHOOTING TESTS

IMPORTANT: The following procedures
may require the use of needle probes
to measure voltage. Failure to use needle
probes will damage the connectors.
TEST #1: Supply Connections
This test assumes that proper voltage is present
at the outlet and, for U.S. 240V electric dryers,
a visual inspection indicates that the power cord
is securely fastened to the terminal block and,
for Canadian 240V electric dryers and U.S. and
Canadian 120V electric dryers, that the power
cord is securely fastened to the wire harness
connection.
240V ELECTRIC DRYER (U.S. Installations):
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the lower
center portion of the back of the dryer.
3. With an ohmmeter, check for continuity
between the neutral (N) terminal of the plug
and the center contact on the terminal block.
 If there is no continuity, replace the power
cord and test the dryer.
 If there is continuity, go to step 4.
4. In a similar way, check which terminal of
the plug is connected to the left-most contact
on the terminal block and make a note of
it. This will be L1 (black wire) in the wiring
diagram.
 When this is found, go to step 5.
 If neither of the plug terminals have
continuity with the left-most contact of the
terminal block, replace the power cord and
retest dryer.
5. Access the machine electronics without
disconnecting any wiring to the timer.

6. With an ohmmeter, check for continuity
between the L1 terminal of the plug (found
in step 4) and pin C on the timer.
 If there is continuity, go to step 7.
 If there is no continuity, check that wires to
the terminal block are mechanically secure.
If so, replace the main wire harness and
test the dryer.
7. Check for continuity between the neutral
(N) terminal of the plug and the door switch.
 If there is continuity, go to step 8.
 If there is no continuity, and the mechanical
connections of the wire are secure, replace
the main wire harness.
8. Visually check that ALL connectors are
fully inserted into the timer and the Start
button.
9. Reassemble all parts and panels.
10. Plug in dryer or reconnect power.
DO NOT REMOVE OR DESTROY
