What does the 02250159-777 temperature switch do?

The 02250159-777 monitors compressor temperature and provides a shutdown signal if temperature reaches an unsafe level.

Its purpose is to help protect the compressor from damage caused by excessive heat.

What temperature is the 02250159-777 rated for?

The 02250159-777 is specified as a 250°F temperature switch.

That is approximately 121°C.

What are the signs that the 02250159-777 temperature switch needs to be replaced?

Possible signs of a failing 02250159-777 include:

  • Compressor shuts down for high temperature when actual temperature is normal
  • Compressor fails to shut down when discharge temperature becomes excessive
  • High-temperature shutdown occurs intermittently
  • Shutdown circuit works only when the wiring or switch is moved
  • Switch remains electrically open when the compressor is cold
  • Continuity testing shows inconsistent operation
  • Terminals are corroded, loose, burned, or damaged
  • Switch body or sensing end is physically damaged

These symptoms can also be caused by real compressor overheating, damaged wiring, poor electrical connections, or shutdown-module problems, so actual compressor temperature should be verified before replacing the switch.

Is this an OEM part?

This is an OEM-equivalent replacement temperature switch designed to meet the same performance standards as the original Sullair switch.  

How difficult is it to install?

Replacing the 02250159-777 is generally a moderate electrical and mechanical compressor repair.

The switch is installed in the compressor’s hot, pressurized discharge system, so proper shutdown and depressurization are essential.

Before replacement:

  • Shut the compressor down completely
  • Disconnect and lock out electrical power
  • Allow the compressor to cool fully
  • Completely depressurize the air/oil system
  • Prevent automatic restart
  • Label or photograph the electrical connection

Installation generally involves disconnecting the switch wiring, removing the existing temperature switch from its mounting port, installing the replacement 02250159-777 using the correct sealing method, reconnecting the electrical circuit, and verifying proper shutdown-system operation.

A technician familiar with portable compressor electrical and air/oil systems should generally perform the repair.
