No guessing
Copy the model number plus the manufacturer part number (MPN). On generator controllers it is printed on the PCB silkscreen or a barcoded label (e.g. Kohler GM104661). On RV fridges, open the lower exterior control box — Norcold boards are stamped 628661 or 639593. On rooftop AC, the data plate sits under the shroud next to the BTU rating.
Type it into the finder above — dashes, spaces, and capitalization are optional, so 0H6680D, 0H6680-D, and 0h6680d all land on the same Generac Nexus controller. If a part has multiple revisions, the product page lists which equipment lines each revision fits.
Check the fitment box (models, voltage, revision notes) against your equipment, then check out with card, PO, wire, or COD. In-stock orders placed before 2 PM ET ship the same business day, and standard freight over $300 ships free.

When a generator, kiln, or fleet vehicle is down, the MPN on the failed part is the fastest path back up. Our catalog is indexed by that number — with fitment notes, specs, and live stock — so you order once, correctly.
Start with a generator control board, an RV rooftop air conditioner, a skid steer attachment, or kiln heating elements.
RV service centers and dealerships ordering fridge boards and AC parts; generator dealers and standby installers stocking controllers and sensors; excavation and landscaping contractors running skid steer attachments; ceramic studios and schools firing kilns; plus municipal shops on NET-30 terms — contact our team. One invoice, one tracking thread, one RMA process — built for purchase orders, not guest checkouts.
Before you order
Read the data plate first: the model number plus the manufacturer part number (MPN). On control boards it is printed on the PCB silkscreen or a barcoded label; on RV fridges it is inside the lower exterior control box (for example Norcold 628661 or 639593); on rooftop air conditioners it is under the shroud on the unit data plate. Enter that number in the search above — dashes, spaces, and capitalization are optional.
No. Search ignores punctuation and case, so 0H6680D, 0H6680-D, and 0h6680d all resolve to the same Generac Nexus controller. If several revisions exist, the product page lists the models each revision fits so you can confirm before ordering.
Yes. We catalog genuine manufacturer components and Tier-1 certified direct replacements sourced through authorized commercial distributors — Kohler, Generac, Dometic, Norcold, Suburban, Coleman-Mach, Lippert, Rhinox, Olympic Kilns, and others. Every listing shows the exact MPN, brand parentage, and known equipment lines.
In-stock orders placed before 2 PM ET ship the same business day. Standard parcel transit is 2–5 business days, and standard freight over $300 ships free. Expedited 1–2 day parcel and palletized LTL freight are available at checkout for heavy attachments and kilns.
Yes, within 30 days, provided electronic boards remain in their original sealed anti-static bag and were never powered on — once power is applied a board cannot be resold as new. Wrong-part and defective returns ship back free with a prepaid label; customer-remorse returns carry a 15% bench-test restocking fee.
PayPal is the primary checkout method: tap the PayPal button after placing the order — the exact total and order reference come pre-filled, so you just log in and hit Send. Cash on delivery is available as a secondary option: pay the courier at delivery. Shops, fleets, and municipalities can request NET-30 purchase-order terms through a quote request.
Often, yes. Send the obsolete MPN, equipment model, and serial through the contact form or a quote request. Our specialists cross-reference superseded numbers — for example older Norcold 621991 boards replaced by 628661 — and Dometic, Atwood, and Coleman legacy lines.
Online checkout serves the 50 US states, with tax calculated by delivery state. Alaska and Hawaii ship parcel via USPS Priority or UPS 2nd Day Air. Canadian buyers can order through a US freight forwarder — email shipping@exactpartsupply.com for a cross-border freight quote.
