TROUBLESHOOTING TESTS

NOTE: These checks are done with the dryer
unplugged or disconnected from power.
TEST #1 Supply Connections
This test should only be done after confirming
proper voltage at the outlet.
1. Unplug dryer or disconnect power.
2. Remove the cover plate from the back of
the dryer. See Figure 3.

3. Make sure the power cord is securely
fastened to the terminal block.
4. With an ohmmeter, check for continuity
between the neutral (N) terminal of the
plug and the center contact on the termi-
nal block. See Figure 4.

Figure 4. Plug-to-terminal connections.
• If there is no continuity, replace the
power cord and test the dryer.
• If there is continuity, go to step 5.
5. 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 Figure 4 and the
appropriate wiring diagram in Section 7.
• When this is found, go to step 6.
• 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.
6. Access the machine control electronics
without disconnecting any wiring to the
control board. See Accessing & Remov-
ing the Electronic Assemblies.
7. With an ohmmeter, check for continuity
between the L1 terminal of the plug (found
in step 5) and P9-2 (black wire) on the ma-
chine control board. See Figure 15.
• If there is continuity, go to step 8.
• 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.
