49P11-843

White Rodgers Cooling Controls 50A65-843 Universal Nitride Ignition Furnace Control, 25 The 50A55-843 universal silicon carbide integrated ignition module employs a microprocessor which continually monitors, analyzes and controls the proper operation of the gas burner, inducer and fan. This one module will replace most of the 50A5x-xxx integrated ignition carbide modules that have been manufactured by White-Rodgers for most OEM applications. The universal module includes an extensive cross-reference, additional jumper wires, additional wiring harness and a jumper for Trane applications. The module also has terminals for powering a humidifier and electronic air cleaner
