COMPONENT TESTS

Supply Connections Test—Electric
This test assumes that proper voltage is pres-
ent at the outlet, and visual inspection indi-
cates that the power cord is securely fastened
to the terminal block.
1. Unplug dryer or disconnect power.
2. Remove the cover plate from 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 termi-
nal block. See illustration below.

• 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. See illustration
above.

• 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 test the dryer.
5. Access the electronic control without dis-
connecting any wiring to it.
6. With an ohmmeter, check for continu-
ity between the L1 terminal of the plug
(found in step 4) and BK (black wire) ter-
minal 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 or repair the main
wire harness and test the dryer.
7. Check for continuity between the neutral
(N) terminal of the plug and P2-1 (white
wire) on the electronic control.
• If there is continuity, go to the Timer
Test.
• If there is no continuity and the me-
chanical connections of the wire are
secure, replace or repair the main wire
harness.
