Why do my Kohler Inverter fans operate in high-speed mode continuously?
- J
  joseph11Sep 6, 2025
  If the fans in your Kohler Inverter are constantly running at high speed, examine the radiator and enclosure openings to ensure there's no blockage restricting airflow. Also, verify the sensor's functionality. Inspect the harnesses from the fuse/relay terminal block to the fans and controller for any damaged leads or terminations. Evaluate the relays for proper operation, check the coil's continuity, and confirm the transition at the specified threshold temperatures.

What to do if Kohler Inverter fan does not transition to high-speed at threshold temperature?
- C
  Casey StephensonSep 8, 2025
  If the fan in your Kohler Inverter isn't switching to high speed when it reaches the threshold temperature, start by checking the sensor's function. Inspect the harnesses from the fuse/relay terminal block to the fans and controller for any damaged leads or terminations. Evaluate the relays for proper operation, check the coil's continuity, and verify the transition at the threshold temperatures.
