      If your Kohler Inverter will not crank, the issue might stem from a weak or dead battery, so recharge or replace it. A blown 15-amp controller fuse could also be the cause, requiring a fuse replacement. Other potential problems include a defective start switch or starter solenoid (replace them), a disconnected remote start cable (reconnect it), or battery connections made in reverse (correct them).

      If your Kohler Inverter will not start, it could be due to several reasons. You may be out of fuel, so replenish it. The fuel filter or air cleaner might be clogged, in which case you should replace the fuel filter and clean or replace the air cleaner. A faulty spark plug could also be the culprit, so replace or regap it. Other potential causes include a shorted or open ignition coil (replace it), a faulty ground (clean and retighten), a loose spark plug wire connection (reconnect and/or tighten), a weak or dead battery (recharge or replace), an incorrect choke adjustment (adjust it), or a low oil pressure shutdown (correct the cause of the shutdown).

      If your Kohler Inverter lacks power, the possible causes include a clogged air cleaner (clean or replace it), improper cooling (inspect the cooling system), engine overload (reduce the load), bad or stale fuel (replace it), a faulty spark plug (replace or regap it), or an incorrect carburetor adjustment (adjust it). For carbon build-up or a governor that is not properly adjusted or defective, have the unit serviced by an authorized Kohler service dealer/distributor.

      If your Kohler Inverter stops suddenly, it could be due to several reasons: being out of fuel (replenish it), a clogged air cleaner (clean or replace the element), or a faulty spark plug (replace or regap it). Additionally, check the oil level for low oil pressure. Also, check the controller voltage supply fuse and the de-icing module fuse (gasoline models); replace them if blown. For a defective de-icing module (gasoline models), have the unit serviced by an authorized Kohler service dealer/distributor.
