Why service your KOHLER with GSHA

• Authorized KOHLER dealer. Our technicians are KOHLER-trained, we perform KOHLER warranty repairs and we handle the warranty claim paperwork for you.
• Genuine KOHLER parts. KOHLER maintenance kits (oil, oil filter, air filter, spark plugs), batteries, cold-weather kits, cellular kits and controller components, matched to your model.
• KOHLER’s maintenance schedule. We service to the intervals in your operation manual and record run hours and readings from the RDC2 controller at every visit.
• Priority service during outages for customers on a GSHA maintenance plan.
• One company for the whole system. Licensed electricians for the transfer switch and panel, gas technicians for the fuel supply, so there is no finger-pointing between trades.

What the annual KOHLER tune-up includes

Our precision tune-up follows KOHLER’s annual service checklist:

• Change engine oil and replace the oil filter and air filter; check or replace spark plugs
• Visually inspect the unit, record run hours and verify it is functioning properly
• Inspect the exhaust system, hoses and belts
• Inspect the governor, voltage regulator and ignition components
• Functional test of the RDC2 controller, exercise settings and transfer switch
• Test and record battery condition and the charging system; inspect the battery heater and cold-weather kit if installed
• Check the gas supply pressure and connections for leaks
• Clean around the generator area and clear the intake and exhaust louvers

Generator maintenance plans

KOHLER generator repairs

Common calls we handle: generator will not start or transfer, low battery or battery-charger faults, low oil pressure or oil-level shutdowns, controller fault codes, transfer switch or load-management problems, gas pressure issues, damaged enclosures and rodent damage to wiring. Because the RDC2 controller stores over 70 diagnostic messages, tell us the display message when you call and we arrive with the likely parts. We also repair older KOHLER RES-series generators and replace units that are beyond economical repair with a current KOHLER model. See also generator repair for all brands.

Winter readiness

KOHLER recommends cold-weather accessories where temperatures drop below 32°F. For northern Illinois and Wisconsin we recommend the KOHLER cold-weather kit (oil heater, breather tube heater and fuel regulator heater) and a battery heater below 0°F. Schedule the annual tune-up in the fall so the oil, battery and heaters are checked before the first ice storm.

Remote monitoring and alerts

Every current KOHLER home generator includes the KOHLER Energy Management app through the RDC2 controller’s Ethernet connection. We set it up at start-up so you (and, if you choose, our service department) see exercise results, faults and maintenance reminders. If your internet router loses power during an outage, the optional KOHLER cellular kit keeps the generator reporting.

KOHLER service FAQs

How often does a KOHLER generator need maintenance?

KOHLER calls for an oil and filter change and full inspection at least once a year or every 100 to 200 running hours, plus air filter and spark plug replacement on the schedule in your operation manual. After a long outage (24 hours or more of run time) an oil change is recommended.

What does a GSHA generator tune-up include?

Engine oil and oil filter change, air filter replacement, spark plug check or replacement, inspection of the exhaust, hoses, belts, governor, voltage regulator and ignition components, a functional test of the controller and transfer switch, battery load and charging-system tests, and a cleanup of the generator area.

Do you offer generator maintenance plans?

Yes. Our SILVER and GOLD Generator Tune-Up plans include a pre-season tune-up and inspection, maintenance reminders and priority service; GOLD adds a larger repair discount and an equipment purchase credit. See the plan pages for current pricing.

Will maintenance by GSHA keep my KOHLER warranty valid?

KOHLER’s limited warranty requires the generator to be installed, registered and maintained per the operation manual by an authorized dealer for warranty repairs. As an authorized KOHLER dealer we perform warranty work, document maintenance and use genuine KOHLER parts.

My generator shows a fault or will not start. What should I do?

Note the message on the RDC2 controller display (or in the KOHLER Energy Management app), leave the switch in AUTO unless there is a safety issue, and call us at (224) 220-3660. The controller stores over 70 diagnostic messages that help us arrive with the right parts.

Do you repair KOHLER generators you did not install?

Yes. We service and repair KOHLER home generators of any age in our service area, including older RES models, and we also service Generac, Cummins, Briggs & Stratton and Champion units.

What should I do before winter?

Have the annual tune-up done in the fall, confirm the battery is under 3 years old and holding charge, make sure the cold-weather kit (oil, battery and regulator heaters) is working, and keep snow cleared from the intake and exhaust louvers.
