PARTS CATALOG
Introduction
This illustrated part catalog has been written to help assist the technician to quickly locate the parts that he or she needs to
make a repair.
The catalog is broken down into different gures which represent different modules of the air conditioning unit. For example;
the chassis, refrigeration system, blower system, or electrical controls. Each gure contains an illustration(s) containing item
numbers and a corresponding item list.
The item list contains the item number, part number, part description, the model it is used on, and the quantity used per gure.
The models will end with a letter indicating the major revision of the model. for example; WCT12A30A. Choose the part that
corresponds with the USED ON MODEL annotation that corresponds to your nameplate.
In some cases there will be an additional “-” letter indicating there has been a minor revision to that model which may have caused
a part number change. For example; WCT12A30A-B. If there are minor revisions listed for a part, and the minor revision that is
listed on your equipment’s nameplate is not listed in the manual please check our online parts viewer for the latest update. If
you still require asistance, call Friedrich customer service(1-800-541-6645) for an explanation.
Items with a - in front of the item number (for example -10), are non illustrated items.
Items with an * in front of the number (for example *10) are non-stocked items. If you require these items contact Friedrich
customer service at (1-800-541-6645) to check for availability and lead time.
