What to do if an individual fan is not operating in my Kohler Inverter?

If a single fan in your Kohler Inverter isn't working, start by checking the fan fuses. Then, check the fan for any obstructions and ensure the fan blades can rotate freely. Verify the fan motor coil for continuity (an open coil). 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 and check for transition at threshold temperatures.
