Shannon G Alpine , CA April 08, 2017 Appliance: Whirlpool Trash Compactor GX900QPHS0 Whirlpool Compactor Gx900qphs0: Compactor would not turn itself off when it reached the end of its compaction cycle. How to replace Directional Switch. Installed a new Directional Switch. Easy to do! Access is through the front panel, no need to pull compactor out from under cabinets. Helps to have a small socket set (1/4 drive) with a small handle cause bolts holding switch are in a tight spot. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
