Bard 8602-053 - Economizer Logic Module

The Bard 8602-053 Economizer Logic Module is an OEM control module used in Bard economizer-equipped wall mount and packaged HVAC systems to manage outdoor air free cooling and damper operation based on sensor inputs, while coordinating compressor staging signals for proper system changeover. This module is a common failure point when an economizer will not enable, dampers will not respond correctly, or cooling stages do not sequence as expected, so replacing it with the correct Bard part number helps restore reliable economizer control and ventilation performance. Because 8602-053 has been listed by multiple suppliers as discontinued or obsolete, confirm the exact replacement and compatibility by unit model and serial number before ordering to ensure the new control matches your economizer actuator and sensor setup.
