When the chiller fault keeps coming back

The chiller trips, but the alarm log does not show the cause.

A sensor has been changed. Maybe more than once.

The chiller runs normally during testing, then fails again in operation.

A compressor has been blamed, but the diagnosis does not add up.

We troubleshoot the chiller and the chilled water system around it to find what is actually causing the fault.

Chiller troubleshooting that finds the cause

Operating data review

We check operating data to understand what is happening when the chiller runs and when it fails.

Controls and sensors

We check the controls and sensors that may be contributing to the chiller fault.

Refrigerant conditions

We check refrigerant conditions as part of the troubleshooting.

Water-side conditions

We check the chilled water system around the chiller for conditions that may be causing the fault.
