The Carrier HK42FZ035 is a genuine Carrier replacement circuit board and replaces the earlier HK42FZ024. The board is the control center of the equipment, reading the thermostat demand and the safety circuit, sequencing the components in order, and shutting the system down and flashing a fault code when a safety opens. Typical signs of a failed board are no response to a call for heat, a blower that runs continuously, or an unexplained lockout.
If your existing board is marked HK42FZ024 or HK42FZ035, this is the current replacement. Confirm the part number before ordering.
