Onan generator serial number and parts lookup prep

Use the official Cummins generator information FAQ to collect generator serial number, model, and parts-lookup details.

Owner-safe checklist

• Record the Onan generator model, spec letter, serial number, hour-meter reading, RV make and model, and exact start, output, or maintenance question.
• Save photos of the generator label, display or switch state, owner paperwork, maintenance records, and any Cummins parts lookup result.
• Use Cummins Onan, Coach Care, an authorized service provider, or qualified generator service for maintenance work, parts, installed power, or repair decisions.
