NOTE: When contacting ADC with electrical questions, please have on hand the correct wiring

diagram number for your particular machine. 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 illustration).

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.
