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

The 50A66-743 is an automatic gas interrupted ignition control that employs a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner, inducer, and fan. signals interpreted during continual surveillance of the thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shutoff during normal operation. these controls incorporate system fault analysis for quick gas flow shutoff , coupled with automatic ignition retry upon sensing a fault correction.

3-fan speeds
• Remote flame sensing
• Humidifier and electronic air cleaner connections (optional)
• 1.5 amp valve relay
• 6 amp igniter relay
• 2.2 amp full load - 3.5 amp locked rotor inducer relay
• 14.5 amp full load - 25 amp locked rotor circulator relay
• Diagnostic indicator flash codes, controls gas valve, igniter, blower, inducer, humidifier and air cleaner
