A plain-English owner's reference: what C.H.I. Overhead Doors makes, where your model number hides, how to decode the diagnostics, and when to hand it to a local pro. We're not affiliated with C.H.I. Overhead Doors — this page exists because the manuals are hard work.
C.H.I. Overhead Doors is a garage door manufacturer founded in 1981 and headquartered in Arthur, Illinois. In 2022 C.H.I. was acquired by Nucor Corporation, the largest American steel producer, from private equity firm KKR, a sale noted for the payout its employee ownership stake delivered to workers. C.H.I. makes residential sectional doors, commercial sectional doors, and rolling steel doors, selling through independent professional dealers rather than retail stores.

C.H.I.'s residential range includes overlay carriage house doors (such as the 5900-series with composite or steel overlays), stamped carriage house and stamped shaker steel doors, traditional raised-panel steel lines (including the widely installed 2250/2251 and 4250-type insulated models), flush and plank contemporary designs such as Skyline Flush, and aluminum full-view doors. Many steel models are offered with C.H.I.'s Accents woodtone finishes, which print realistic wood grain on steel. Insulation options span non-insulated, polystyrene, and polyurethane construction, and wind-load-rated builds are available for code-driven markets.
C.H.I. places identification information on the ends of the door sections, on the left or right section edge, rather than always on a back-of-door sticker; raise the door slowly and check between sections and on the end stiles. Note that C.H.I. labeling emphasizes model and production data, and older doors may not show a distinct serial number, so photos of the panel profile help a dealer confirm the model.
Search cpsc.gov/Recalls for C.H.I. Overhead Doors along with any model or production data from the section-edge labeling, and contact an authorized C.H.I. dealer via chiohd.com for factory bulletins. Because some C.H.I. doors lack a visible serial number, the dealer who installed the door is often the fastest route to its production records.

Replacement sections, overlays, and window inserts must match the exact C.H.I. model and panel stamping, identified from section-edge markings and panel measurements; the Accents woodtone finishes also need to be matched by pattern name for a consistent look. Springs, track, hinges, and rollers are standard industry hardware any professional can service. C.H.I. does not make openers, so any properly rated opener works once the door is correctly spring-balanced.
Nucor Corporation, the largest U.S. steel producer, acquired C.H.I. in 2022 from KKR. The acquisition drew national attention because C.H.I.'s employee equity program paid substantial sums to factory workers at the sale. C.H.I. continues to manufacture in Arthur, Illinois, and sell through independent professional dealers.
Check the ends of the sections, the left and right edges, and the end stiles on the interior side; C.H.I. typically marks doors there rather than with a large back-of-door sticker. Older doors may lack a serial number entirely, so a dealer may ask for panel-profile photos and measurements to confirm the exact model.
Usually, if the model and finish pattern are still in production. C.H.I.'s Accents woodtone finishes are applied in named patterns, so a dealer needs both the door model and the specific finish name to order a matching section. Sun-fading on older doors can make even a correct match look slightly different at first.
