Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RHH060H0BA0AAAA heat pump. The control board governs the defrost cycle, reversing valve, compressor timing, and safety lockouts for the outdoor unit. A failed board commonly shows up as a heat pump that ices over, never exits defrost, runs nonstop, or won't energize the compressor. Installing the correct OEM board restores proper sequencing and safeguards the compressor against short-cycling and improper switching.
