Four Seasons 20895 Pressure Switch Overview

The Four Seasons Pressure Switch 20895 is a system-mounted HVAC cut-off switch built for low-pressure A/C control. It uses a red plastic and metal housing, a male round connector, and a female 3/8 in. x 24 fitting for direct service replacement on the HVAC system.

Compatible With Buick Century, Oldsmobile Cutlass Ciera, Pontiac 6000, Chevrolet Celebrity, and Pontiac Sunbird applications, this low cut-out pressure switch helps maintain proper refrigerant circuit operation. Four Seasons 20895 meets or exceeds OEM requirements and uses a 2-terminal, pressure-style design.

Key Features

  • Low cut-out HVAC pressure switch for system-mounted installation
  • Pressure switch style with open compressor state
  • Male round connector with 2 terminals
  • Female fitting, 3/8 in. x 24 thread size
  • Operate psi low off: 32; operate psi low on: 44
  • Plastic / metal construction in red
  • Meets or exceeds OEM specifications

Product Details

The Four Seasons Pressure Switch line focuses on HVAC control components that monitor refrigerant pressure and help protect the air conditioning system from low-pressure operation. Part number 20895 is a low cut-out switch that mounts on the system and uses the specified harness connector 37222 for service matching. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use Four Seasons 20895 when servicing a low pressure A/C cut-off switch on supported Buick Century, Oldsmobile Cutlass Ciera, Pontiac 6000, Chevrolet Celebrity, and Pontiac Sunbird vehicles. The 20895 pressure switch is built for direct replacement where the original HVAC system-mounted switch uses the same connector and thread configuration.

What It Helps Fix

  • A/C compressor cycling caused by low refrigerant pressure switch faults
  • Compressor cut-off issues tied to an open pressure switch
  • HVAC system shutdown from a failed low-pressure control signal
  • Intermittent air conditioning operation related to switch wear
  • Incorrect pressure switch readings at the HVAC system mount

Installation Notes

Verify the connector style, terminal count, and 3/8 in. x 24 fitting before installation. This switch is system mounted, so confirm the original location and harness connector match the vehicle’s HVAC setup. After installation, check refrigerant charge and system operation to confirm the low cut-out and low-on pressure points are functioning as expected.

Quality Assurance

Four Seasons 20895 is manufactured to meet or exceed OEM requirements for the listed applications. It is a direct-fit HVAC pressure switch replacement for supported Buick Century, Oldsmobile Cutlass Ciera, Pontiac 6000, Chevrolet Celebrity, and Pontiac Sunbird models.
