Older stove? If the cable between your control panel and PCM is a wide 20-pin ribbon (most stoves built before about 2020), you need the legacy PCM board and legacy control panel instead.

Which part number? Your model and serial number are on the rating label and the cover of the owner's manual. Match the part number on each product page to the parts list in your manual before ordering, since some parts changed partway through production.
