Frequently Asked Questions

Is the 043374 temperature switch compatible with my Sullair compressor?

The 043374 is a Sullair temperature switch for compatible compressor applications. Confirm compatibility by matching 043374 in your compressor manual and verifying the model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 043374 temperature switch do?

The 043374 monitors temperature at its installed location and sends an electrical signal when the system reaches its specified temperature condition. Depending on the compressor configuration, it can help:

  • Monitor compressor operating temperature
  • Support high-temperature protection
  • Signal the control system when an abnormal temperature condition occurs
  • Help prevent continued operation during overheating
  • Support safer, more reliable compressor operation

What are the signs that the 043374 temperature switch may need replacement?

Common symptoms can include:

  • High-temperature warning or shutdown with no obvious overheating condition
  • Compressor failing to continue operating after reaching normal temperature
  • Intermittent temperature-related fault codes
  • Damaged wires, terminals, or switch housing
  • Switch failing continuity or temperature-response testing
  • Repeated temperature-control issues after airflow, oil level, and cooler condition have been checked

These symptoms can also be caused by low lubricant, a dirty cooler, blocked airflow, a failed fan, wiring problems, or an actual overheating issue. Inspect the complete cooling and control system before replacing the 043374.

Is this an OEM part?

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

How difficult is it to install?

Installing the 043374 is generally a moderate maintenance task because it involves the compressor’s electrical and temperature-monitoring systems.

Before service, the compressor should be:

  • Fully shut down
  • Secured so the engine or motor cannot start
  • Electrically isolated if required
  • Cooled to a safe working temperature
  • Verified so no pressure remains at the service location if the switch is installed in a pressurized circuit

Installation typically involves documenting the wiring and switch location, removing the original component, installing the replacement 043374, reconnecting the wiring, and verifying normal temperature-control operation after startup.

Do you carry other parts for Sullair?

Absolutely. We stock a range of air filters, oil filters, valves, synthetic oils, and many other maintenance parts for Sullair equipment. If you don’t see what you need, just ask and we’ll help you find it.
