Description
The Carrier 17122000050501 Main Control Board is the primary electronic oversight module that manages and coordinates HVAC system operation. It processes input signals from thermostats, sensors, and safety parts, then controls components such as the blower motor, compressor, and relays to ensure proper system sequencing. It operates as the central logic unit that handles heating, cooling, and fan operations with correct timing and safety logic. Mounted inside the indoor air handler or furnace electrical compartment, it supports system communication and fault detection in the networking state.
