HVAC / Furnace Timing / Relay Control Board

This board is a time-delay relay / blower control module used in Goodman, Amana, and related HVAC systems (furnaces, packaged units, heat pumps, air handlers). It manages blower operation sequences and safe delays after heating or cooling events.

Key Features

• Controls blower motor delay and relays for safe cycling before, during, and after heating or cooling phases.

• Incorporates signal control circuitry, relay switching, timer logic, and diagnostic LED indicators on board.

• Designed to OEM specifications in timing intervals, voltage handling, and sequencing logic.

• Built with heat-tolerant printed circuit components, protective coatings, and fuse protection for durable use in HVAC enclosures.

• Compatible with Goodman / Amana systems and other HVAC units that list control board PCBFM103S or equivalent — consult the original control board part number when replacing.

• Always verify compatibility by matching this board to your HVAC model number and control system before ordering.
