Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before
operating.
Failure to do so can result in death or
electrical shock.
nOTe: These checks are done with the dryer
unplugged or disconnected from power.
TeST #1 Supply Connections
This test assumes that proper voltage is
present at the outlet, and visual inspection
indicates that the power cord is securely
fastened to the terminal block (electric dryer)
or wire harness connection (gas dryer).

1. Unplug dryer or disconnect power.
2. Remove the cover plate from the upper right
corner 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. See illustration above.
• If there is no continuity, make sure the
white wire is at the center position on the
terminal block. If not, correct the wiring. If it
is, then replace the power cord and test the
dryer.
• If wired correctly and 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
test the dryer.
5. Access the machine control electronics
without disconnecting any wiring to the dryer
CCU (control board). (See page 4-52).
6. With an ohmmeter, check for continuity
between the L1 terminal of the plug (found
in step 4) and P9-2 (black wire) on the dryer
CCU (control board). (See page 4-54).
• 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 P8-3 (white wire) on
the dryer CCU (control board).
• 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.
