Generators & power equipment

This department covers Generators & power systems, Generator parts, controllers & accessories Every listing shows the exact manufacturer part number, brand parentage, and known equipment lines so you can match your failed component precisely. Current live catalog: 3,086 verified parts.

Designed for Standby Home Generators, Commercial Prime Power, RV Onan Generators. Mission-critical prime and standby power controls, electronic governor modules, automatic transfer switch boards, voltage regulators, and tune-up components.

Cross-referenced stock includes Kohler, Generac, Cummins Onan, plus Tier-1 certified direct replacements. Always match the MPN printed on your existing component — brand alone is not enough for fitment.

Read the MPN from the equipment data plate, label, or control board, search it above, then check the fitment box for models, voltage, and revision notes. Dashes, spaces, and capitalization are optional in search.

In-stock orders placed before 2 PM ET ship the same business day with 2–5 day parcel transit. Free freight over $300.

Manufacturers replace boards and components without renaming the equipment. When a listing states which legacy numbers it replaces, that line is the authority — match your old number to it before checkout. If neither the fitment box nor the replacement line names your number, send photos of the data plate and board label instead of guessing.

Unused parts in original packaging can be returned by mail within 30 days for a refund — return shipping is free. Powered-on control boards cannot be returned as new, so confirm the MPN and connector match before installation.

Every purchasable listing carries at least one verified product photograph, and the feed only advertises parts with verified photography. Compare mounting points, connectors, and dimensions in the photos against your removed component before ordering.

The buying and repair guides linked below this catalog walk through data-plate locations, MPN matching, and the install checks technicians use most. Start with the guide for your equipment family, then search the exact part number above.
