NOTE: When contacting ADC with electrical questions,
please have on hand the correct wiring diagram number for
your particular dryer. This number is located on the top
right-hand corner of the diagram. It is a six (6) digit number
followed by a letter to distinguish the revision dates (refer to
the illustration below).
The wiring diagrams used in Troubleshooting are specifically
for dryers manufactured at the time of publishing. Your
particular model may vary slightly depending on the date of
manufacturing and options available. The correct wiring
diagram and number is either taped to the rear of the control
door on each dryer, or placed in the control box. If your
particular diagram is lost or unreadable, call ADC with the
serial number of the dryer. ADC will be more than happy to
send you a diagram by fax or mail.
