ICP Furnace Control Circuit Board for WPA3304000RKC1 — OEM 1178001 | Ships Today

Overview

This is the OEM control circuit board (part number 1178001) for the ICP / Tempstar / Heil WPA3304000RKC1 packaged unit. The control board is the brain of the system: it manages the ignition sequence, sequences the inducer and blower motors, monitors the safety circuit (limit and pressure switches), and times the heating and cooling cycles. When this board fails, the unit may not power up, may lock out on ignition, may run the blower continuously, or may fail to respond to the thermostat at all. A direct factory replacement restores reliable 24V control and proper cycle timing.
