Summary
MaxxPower No Idle Battery-Powered A/C System Diagnostic Guide; models equipped with feature 16UZL
•
•
•
•
Due to product improvements, the terminals were changed to a cluster block after 7/16/2012.
All cold loop service parts are built with the cluster block style compressor.
The cluster block style can be identified by its black color compressor.
The flag style compressor is a purple / blue color.
◦ The compressor controller is not compatible between the two units.
• If the vehicle was built with the flag type compressor (purple / blue), when replacing the cold loop, the compressor controller will also
need to be replaced.
If when removing the old cold loop it is found that the compressor in the unit is the cluster block style (black), the compressor controller
should not be replaced.
If you have a failed compressor controller with the Purple (Blue) Compressor, you can replace the compressor controller.
• Refer to the Parts Information section for the part number information for the different compressor controller circuit boards

Service Parts Based on Serial Number Prefix
The serial number can be found on a tag of the MaxxPower HVAC box. To ensure that the proper components are ordered, the serial number
prefix will determine what compressor this vehicle was built with. The tag faces the lower bunk frame front wall, and the serial number will be
in the format of BVX000035. Please see the photos below for the tag example and an example position.
