Check a part or accessory pairing

Loading part or accessory choices…

Selected: GUAT-340 · Read its reference. Selection identifies a record; it does not confirm fitment.

Choose the equipment or accessory brand separately from the component brand. A missing identifier is unverified. Use the model library to identify your equipment and its official documents.

An accessory pairing, including a receiver or wall console, applies only to the exact listed pair and source conditions. It does not establish suitability for your installed opener or compatibility through another device.

Choose the equipment or accessory brand to load its published identifiers.

Use the production date on the label or records, not the purchase date. Leave blank if unknown.

Use part and model numbers only. Never enter a serial number, PIN or access code. Your entry is used for this lookup and is not put in the page address, saved in browser storage or sent to analytics.
