  • Replace if the arm is cracked, bent, or broken
What's included:
  • Includes: 1 lid hinge arm
Install notes:
  • Disconnect power before servicing; also shut off water supply
  • Support the lid to prevent damage; tape it in place or have a helper hold it
  • Remove hinge cover and mounting hardware; note orientation and transfer any spacers/bushings
