Nordyne 1023981R Low Pressure Switch, Opens 20 PSI / Closes 35 PSI

Description

Nordyne 1023981R Low Pressure Switch

The Nordyne 1023981R is an OEM low pressure switch engineered to protect refrigeration and HVAC systems from operating under unsafe low-pressure conditions. With a precise open setpoint of 20 PSI and a close (reset) setpoint of 35 PSI, this switch automatically interrupts system operation when refrigerant pressure drops below the safe threshold, helping prevent compressor damage and extending equipment life.

Key Features

• OEM Nordyne replacement part — SKU 1023981R
• Opens (trips) at 20 PSI to protect against low refrigerant pressure
• Closes (resets) at 35 PSI once safe pressure is restored
• Designed for use in Nordyne-branded HVAC and refrigeration equipment
• Helps prevent compressor damage caused by low refrigerant charge or loss of charge
• Direct OEM replacement for reliable, accurate performance

Application

This low pressure switch is a direct OEM replacement component for compatible Nordyne heating, cooling, and heat pump systems. It monitors refrigerant circuit pressure on the low side and cuts power to the compressor when pressure falls below the open setpoint, safeguarding the system until normal operating pressure is restored.
