How to fix no AC output on my Kohler Portable Generator?
- N
  nweberJul 31, 2025
  If your Kohler Portable Generator has no AC output, check if the line circuit breaker is in the OFF position and switch it to the ON position. Also, reduce the load on the generator if the circuit breaker is tripping due to an overload. If the line circuit breaker is tripping because of a short circuit or if the auxiliary winding circuit breaker tripped, contact an authorized Kohler distributor/dealer for service. If the auxiliary winding circuit breaker trips repeatedly after you reset it (it is located in the controller’s service access area), contact an authorized Kohler distributor/dealer for service.

  If your Kohler Portable Generator cranks but doesn't start, starts hard, lacks power, or operates erratically, try the following: * Clean and/or replace the air cleaner. * Recharge or replace the battery if it's weak or dead. * Clean and tighten the battery connections if they are poor. * Check the spark plug wires to ensure they are properly connected. * Check for oil leaks and add oil if the level is low. * Check the fuel supply and valves to ensure sufficient fuel pressure. If these steps don't resolve the issue, contact an authorized Kohler distributor/dealer, as it may indicate an engine malfunction.
