Four Seasons 20056 HVAC Cut-Off Switch
Four Seasons Pressure Switch 20056 Overview
The Four Seasons 20056 is a system-mounted HVAC cut-off switch for low-pressure A/C control. Built with a yellow plastic and metal body, a round female connector, and an M12 x 1.50 female fitting, it is made for direct pressure-switch service on the HVAC system.
This Four Seasons Pressure Switch line is focused on accurate A/C pressure control for service replacement needs. Part number 20056 meets or exceeds OEM requirements and uses a 2-terminal, low cut-out design with open comp operation.
Key Features
- Low cut-out HVAC pressure switch for A/C system protection
- System-mounted design with M12 x 1.50 female thread
- Round female connector with 2 terminals
- Open compressor control configuration
- Plastic and metal construction
- Yellow housing for identification
- Meets or exceeds OEM specifications
Product Details
Four Seasons 20056 is a pressure switch used in low-pressure A/C cut-off applications to monitor refrigerant system pressure and signal the HVAC circuit when pressure drops below the operating threshold. It operates at 11 psi low off and 22 psi low on, making it a direct-fit service part for vehicles that use a system-mounted pressure switch with this connector and thread style. This part cross-references UAC SW11000C for the same application.
Compatible With Ford Escape 2008-2012, Mercury Mariner 2008-2011, Mazda Tribute 2008-2009, Ford Taurus 2002-2005, and Mercury Sable 2002-2005. Four Seasons 20056 is also referenced by interchange numbers including 1711524 and 172286-style service listings for related HVAC repair needs.
Common Uses
- Restoring low-pressure A/C cut-off function
- Replacing a failed HVAC pressure switch
- Addressing intermittent compressor cycling caused by pressure-signal faults
- Correcting A/C shutdown from inaccurate low-pressure readings
- Repairing system-mounted switch issues on Ford, Mercury, and Mazda applications
Installation Notes
Verify the connector shape, terminal count, and M12 x 1.50 thread before installation. This switch mounts on the HVAC system and should be matched to the vehicle’s low-pressure cut-off specification. Confirm the refrigerant system is properly serviced and inspect the harness connector before replacing the part. For fitment-based searches, this is a direct replacement for a Ford Escape HVAC pressure switch, Mercury Mariner A/C cut-off switch, or Mazda Tribute low-pressure switch when the listed application matches.
Quality Assurance
Four Seasons 20056 is built to meet or exceed OEM requirements for pressure-switch service replacement. The Four Seasons Pressure Switch line is used for HVAC control applications where accurate pressure signaling and dependable electrical connection are required.
