GDI is a parts and accessories line rather than a door brand: gear kits, logic boards, light covers, wall controls and similar pieces that keep older openers running without replacing the whole unit. It's a small list, but these are the items we reach for most on a weekday opener repair in Vancouver or Burnaby.
