Lennox 32W87 Pressure Switch
The Lennox 32W87 Low Pressure Switch is a critical safety component designed for precise refrigerant monitoring in high-efficiency Lennox HVAC systems. Engineered as a 30/10# low pressure switch, this SPST (Single Pole Single Throw) safety resets automatically, interrupting the control circuit if suction pressure drops below 10 PSI to prevent compressor damage from loss of charge or vacuum operation. It features a 30 PSI reset point, ensuring the system stabilizes before resuming cooling cycles. This OEM Lennox replacement part is built to withstand high-cycling environments and maintain calibration accuracy under extreme thermal stress. For service technicians, utilizing the 32W87 pressure switch ensures seamless integration with existing wire harnesses and mounting brackets, maintaining the factory-specified safety parameters of the unit. Proper installation of this refrigerant pressure safety switch is essential for protecting the compressor against low-pressure conditions caused by thermal expansion valve failures or refrigerant leaks.
- Factory Calibrated Precision: Fixed 10 PSI cutout and 30 PSI cut-in points ensure reliable compressor protection without the need for field adjustments.
- OEM Compatibility: Exact drop-in replacement for Lennox 32W87, eliminating common alignment issues associated with universal aftermarket switches.
- Automatic Reset Logic: Automatically re-engages the contactor once pressure stabilizes, reducing unnecessary service calls for simple pressure fluctuations.
- Durable Construction: High-grade internal diaphragms and contacts are designed to handle the inductive loads of standard 24V control circuits.
Common HVAC Technician Questions
What are the specific trip points for the 32W87?
This switch is rated for a 10 PSI cutout (normally closed contacts open) and a 30 PSI cut-in (contacts close), making it ideal for standard R-410A low-side monitoring.
Will this switch prevent compressor liquid slugging?
Yes, by cutting the circuit when pressure drops too low, it prevents the evaporator from freezing and helps mitigate the risk of liquid refrigerant returning to the compressor crankcase.
Is the 32W87 compatible with other refrigerant types?
While primarily used in Lennox R-410A systems, compatibility is determined by the 10/30 PSI setpoints; always verify the system's specific pressure requirements before installation.
