Cummins Onan contact support prep

Use the official Shop Cummins contact page to prepare Onan generator model and support-routing details before contacting Cummins.

Owner-safe checklist

Record the Onan or Cummins product model, serial number, purchase date, symptom, operating hours if visible, and the part or product category involved.
Save photos of the product label, purchase record, safe visible hour display if present, and the Shop Cummins contact page title.
Use Cummins/Onan support or qualified generator service for startup problems, shutdowns, abnormal sound, odor, warranty questions, parts questions, or unsafe operation.
