Control Boards from Cedars HVAC coordinate the sequence of operation in air conditioners, furnaces, heat pumps, and refrigeration units. A board reads thermostat and safety inputs, then energizes relays, motors, valves, ignition components, and compressor circuits in the proper sequence. Replacement boards must match the equipment model or approved cross-reference, connector layout, voltage, software or dip-switch settings, and heat-pump or furnace application. Most residential control circuits are 24 volts, even though the board may manage 120- or 240-volt loads through relays. Brands such as Trane, Carrier, and LG use model-specific controls. Cedars HVAC offers efficient ordering for service-company replacement stock.
