Onan P2500i Model and GSN Prep

Use the Cummins Onan P2500i product page to record model, GSN, and support details before service.

Owner-safe checklist

• Record the P2500i model, A074Z433 reference, GSN or product identifier if shown, hours if visible, symptom, load condition, and purchase paperwork.
• Save photos of the nameplate, display, exterior condition from normal access, accessories, and product page used for comparison.
• Shut the generator down for CO alarm, exhaust concern, fuel odor, abnormal heat, unsafe power behavior, or repeated shutdown.
• Use Cummins Onan support or qualified generator service for engine, installed power, fuel system, exhaust, parts, warranty, or repair decisions.
