Dorman 904-610 A/C Pressure Switch

Dorman 904-610 is a direct replacement HVAC pressure switch for R134A air conditioning systems. It addresses common failures caused by corroded terminals or a damaged connector on the original sensor, helping restore A/C operation on select Ford, Lincoln, Mercury, and Mazda vehicles.

Key Features

  • Direct replacement A/C transducer switch for specific applications
  • 5-volt sensor with 3-pin male terminals and female round connector
  • Designed for R134A refrigerant systems
  • Metal housing with bolt-on mount and 10 mm thread diameter
  • Pressure limits: closed at 260 PSI and open at 475 PSI
  • Maximum pressure reading of 500 PSI
  • Black connector and black housing for OE-style service replacement

Detailed Description

This HVAC pressure switch is built to replace the original A/C transducer on vehicles where the factory unit has failed due to electrical corrosion or connector damage. Dorman 904-610 is a specific-fit replacement for a wide range of applications, including 2007-2010 Ford F-150, 2006-2010 Ford Explorer, 2005-2010 Ford Mustang, 2003-2011 Ford Crown Victoria, and 2009-2013 Mazda 6. It also cross-references Standard Ignition PCS120 for the same application.

Use this part when the air conditioning system needs a pressure signal restored for proper compressor control and system operation. The Dorman 904-610 part number is also referenced in service searches for Ford Escape, Lincoln Navigator, Mercury Grand Marquis, and Lincoln Town Car HVAC repairs.

Common Issues It Can Help Solve

  • Air conditioning stops cycling or will not engage
  • Corroded terminals at the original pressure sensor
  • Broken or damaged connector on the factory switch
  • Incorrect pressure signal to the HVAC control system
  • Loss of A/C performance on R134A-equipped vehicles

Installation Notes and Tips

Verify refrigerant type, connector style, thread diameter, and pressure specifications before installation. This is a bolt-on sensor with a round female connector and 3 male terminals, so the replacement should match the original electrical and mounting design. Confirm vehicle-specific fitment for your Ford, Lincoln, Mercury, or Mazda application before service.

Quality Assurance

Dorman manufactures replacement parts for direct-fit service applications, and this pressure switch is built to match the original function needed to restore air conditioning operation on listed vehicles.
