Westinghouse 624736R Air Handler Control Board

Product Description

The WESTINGHOUSE 624736R is a replacement control board designed for residential indoor air handlers. The control board manages the electrical sequencing and blower motor operation within the air handler, serving as the central logic component that coordinates system functions. Licensed HVAC technicians install this board as a direct OEM-style replacement when the original board fails due to component burnout, failed relays, or board-level faults. The 624736R is matched to specific Westinghouse air handler model families and restores factory control functionality upon installation.

This control board is intended for use in residential indoor air handler applications. It is compatible with the B6BM-X60K-C, B6BMMX60K-C, and B6EMMNX36K-B indoor air handler units, covering the B6BM-X, B6BMMX, and B6EMMN model families. Typical installation involves swapping a failed board in a split-system or heat pump air handler configuration. HVAC service technicians performing warranty or post-warranty repairs will find this board a direct fit for the listed models.
