Customer Questions and Answers for Power Nut (Trash Compactor Ram Drive) by Whirlpool

Best Seller
Manufacturer Part
4.89 (64)
By: Whirlpool
Part Number: OEM18034641
Manufacturer Part Number: WP777533

This power nut threads onto the trash compactor's drive screw to raise and lower the ram. Replacing a worn nut restores smooth ram travel and helps prevent binding, stalling, or a ram that doesn't move.

  • Threads onto the drive screw to convert motor rotation into up/down ram movement
  • Worn or stripped threads can stop ram movement or cause binding under load
  • Common symptoms: motor runs but ram doesn't move; grinding/stripping noises; ram stuck partway up or down
What's included: 1 power nut. Installation notes:
  • Disconnect power at the breaker; pull the compactor from the cabinet as needed for access
  • Support and secure the ram before removing the nut to prevent sudden movement
  • Inspect the drive screw and ram guides for wear; replace any damaged parts
  • After reassembly, run a full cycle to ensure smooth, complete ram travel
