Ruud 47-105415-04 Air Handler Control Board

Product Description

The RUUD 47-105415-04 is a genuine OEM communicating control board designed for use in compatible air handler systems. This board manages the communication and operational logic between the air handler and other system components, coordinating blower motor operation, auxiliary heat sequencing, and system status signaling. It arrives new in original factory packaging, making it a direct fit replacement rather than an aftermarket or universal substitute. Licensed HVAC technicians performing air handler service or control board diagnostics will find this a straightforward OEM swap.

This control board is intended for installation in communicating air handler systems where the existing control board has failed or been damaged. Because this is not a universal part, it applies only to specific Ruud air handler models and serial number ranges. Technicians should verify the model and serial number of the unit before ordering to confirm proper fitment. Residential split-system and packaged communicating air handler configurations are the typical application context.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect all power to the air handler at the breaker before removing or installing the control board.
