The genuine OEM Lennox 97M60 defrost control thermostat senses coil temperature on your Lennox heat pump and signals the defrost board when ice begins to build on the outdoor coil. By initiating and terminating the defrost cycle at the correct temperatures, it keeps the coil clear so the system can maintain heating efficiency in cold, damp weather.

When this thermostat fails, you may see the outdoor coil freeze over with heavy frost or ice, reduced heating output, the unit stuck running in or out of defrost, or excessive defrost cycles that waste energy. A sensor that stays open or closed will disrupt the entire defrost sequence.

OEM matters because the 97M60 is calibrated to the exact open and close temperatures your Lennox defrost control expects, ensuring cycles start and end at the right moment. Aftermarket thermostats with different setpoints can leave the coil iced or force needless defrosts that strain the compressor. Keep your heat pump running efficiently through winter with the genuine Lennox part.
