Lennox High Pressure Switch

The Lennox High Pressure Switch is a refrigerant high-pressure safety control for Lennox heating and air conditioning systems. It monitors discharge-side refrigerant pressure and opens its electrical contacts when pressure rises above the switch's set point. This shuts down the compressor and helps protect the compressor and the rest of the refrigerant circuit from damage caused by excessive head pressure. It is also sold as an HVAC high pressure cutout switch, high-pressure limit switch, or A/C pressure control.

Key Features:

• Pressure-activated safety switch that interrupts the control circuit when pressure is too high
• Helps protect the compressor and refrigerant system components from over-pressure conditions
• Made as a Lennox replacement part for dependable operation and a proper match to the original equipment
• Available in several pressure settings to suit different Lennox systems
• Simple replacement of a failed or out-of-spec switch

Choose the variant whose part number and pressure setting match your original Lennox switch. A correct high pressure switch helps the system run safely and reliably and keeps the unit protected under abnormal operating conditions.
