Description
The Lennox 93W01 is an OEM high-pressure switch with automatic reset, engineered to protect refrigeration and HVAC systems from potentially damaging high-pressure conditions. Designed as a direct Lennox replacement part, this switch monitors system refrigerant pressure and automatically interrupts operation when pressure exceeds safe thresholds — then resets itself once normal operating conditions are restored, minimizing system downtime.
Key Features
