Replacement Motor, 24V

This OEM furnace control board is engineered as a direct replacement for compatible Lennox HVAC systems utilizing single-stage furnaces with PSC blower motors. The board manages critical furnace operations including gas valve, ignitor, blower, inducer, humidifier, and air cleaner functions, making it an essential component for system reliability and performance. The control board operates on 25 VAC 60 Hz input voltage with maximum input current capacity of 45 amperes at 25 VAC. It features integrated load management with humidifier control rated at 1.0 ampere for both 24 VAC and 120 VAC applications, and electronic air cleaner control at 1.0 ampere 120 VAC. Flame detection utilizes a precision microammeter measurement system with minimum detection threshold of 0.25 microamperes DC and maximum leakage resistance of 100 megaohms, ensuring accurate ignition monitoring and safety operation. Environmental specifications accommodate demanding HVAC applications with operating temperature range from negative 40 degrees Fahrenheit to 175 degrees Fahrenheit and humidity tolerance from 5 percent to 93 percent relative humidity. These robust parameters ensure consistent performance across seasonal variations and diverse climate conditions. Ideal for residential and light commercial heating applications, this replacement board restores furnace control functionality when original equipment fails. Installation is straightforward for qualified HVAC technicians familiar with Lennox systems. This component meets OEM specifications and provides reliable, long-term operation for compatible Lennox furnace models.
