Lennox 84M96 Pressure Switch 340793-762 The manual override is aThe Lennox 84M96, also identified as model 100216 01, is a high precision loss of charge pressure switch engineered to safeguard compressors against the catastrophic effects of low refrigerant levels. As an essential HVAC safety control, this switch continuously monitors the system's low side pressure, automatically cutting the 24VAC circuit to the contactor if levels drop below critical thresholds. This prevents the compressor from operating in a
