Kohler Diesel Generator Repairs & Servicing

We service Kohler diesel standby sets to the engine schedule on the plate, and we test the battery charger, because Kohler standby units often fail to crank after long idle spells.

Where an ATS is fitted, we test the transfer. A short unloaded exercise run checks that the set starts; a full service checks that it will carry your load.

When a Kohler diesel will not crank, we check the standby battery, the starter and any Kohler panel inhibit before ordering a fuel part.

When it cranks without firing, the usual causes are a blocked fuel filter, air in the line or a solenoid that does not open.

Kohler diesel sets use Kohler controllers or third-party panels, depending on the installation. We read the alarm from the panel on your set and trace it for that controller.

When a Kohler diesel runs but the building stays on mains, we test the ATS and the panel’s start output.

For overheating on enclosed sets, we check coolant, the radiator and airflow through the enclosure, and confirm a temperature trip on a long run before listing cooling parts.

We measure voltage at the breaker once engine speed is stable, then test the AVR and alternator.

Book a repair when your Kohler diesel fails to start, trips on load, shows a panel shutdown or loses output during an outage.

Book a service when fluids and filters are due and the set still runs on its exercise schedule.

A fuel or battery repair on a moderate-hour Kohler diesel is usually worthwhile. Major engine work on a high-hour installation needs a careful look at the alternatives.

When the engine, alternator and panel all need major work, we compare replacement with repair using the condition we measured.
