Do-It-Yourself Stories from Customers like You Problem with detergent cup lid.   John M. • Craig , CO • November 27, 2017

The foam was shot on the detergent cup lid. Hard as a rock. Causing caking problems, dribble down the inside wall of the door and leaving lumps of detergent. Cut the door in half wit aviation snips and pulled out the two halves. Discovered at this point that the spring had gone soft. Bought one ahead of time, so I was set. Put the spring on the left pin, put the spring pin in the door, slipped the door into place (open) and put the right pin in with pliers. Door snaps open now. Read more

Switch Mounting Screw
Genuine Whirlpool part
By: Whirlpool
Part Number: WP9740848

The Switch Mounting Screw is an OEM part compatible with Whirlpool washing machines. This screw securely mounts the cycle selector switch within the control console assembly. Proper fastening ensures dependable operation of control functions.

Symptoms of a bad mounting screw include:

  • Loose or rattling switch within the console face  
  • Difficulty selecting cycles as buttons wobble out of place
  • Water intrusion hastening corrosion of electrical terminals
  • Potential shock hazards if live connections are exposed

This Whirlpool replacement screw restores a tight mounting point. It is compatible with brands like Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.
