Description
The Carrier HK42FZ034 is a factory authorized control board designed for select Carrier, Bryant and Payne single stage gas furnace models. This control module acts as the “brain” of the furnace — managing ignition, burner operation, blower motor, safety circuits, and more. It supports 24 V thermostat control, integrates full safety shut off for ignition failures, and provides diagnostics and compatibility with many existing installations.
