Microwave Diode
Genuine Whirlpool part
By: Whirlpool
Part Number: W11256462

Microwave won't heat but hums loudly? The diode regulates power to the magnetron. Test with multimeter—reads one direction only. Moderate DIY repair.

Do-It-Yourself Stories from Customers like You Loud hum/buzz & no heat   Greg S. • Springfield , VA • November 30, 2015

Replacing a magnetron in my particular 9-year-old microwave (a microwave/hood combination) was not a simple “plug & play” operation. That is why I am placing this in the slightly difficult area. First, it takes 2 people to remove the microwave from the top of the stove. Next the main outer panel need to be removed. After that, 2 sheet metal panels need to be removed in order to expose the high voltage components for testing. Always discharge the high voltage capacitor first before doing... Read more

Cooking Tray Coupler
Genuine Whirlpool part
By: Whirlpool
Part Number: W10435116

The Cooking Tray Coupler is an OEM part replacement part for Whirlpool microwaves. It securely connects the two halves of the microwave cooking tray together, allowing for easy placement and removal of food items. 

Symptoms of a bad cooking tray coupler include:

  • The cooking tray separating into two loose pieces that do not stay connected
  • Food sliding off or falling through gaps in the disconnected tray halves 
  • Inability to use the microwave cooking tray properly

Causes of a bad coupler can be cracks, breaks, or wear over time that compromises its connecting ability. 

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Note: This coupler is compatible with the glass tray that has the 3 half circles that engage the coupler. In some cases, the factory used a tray that has 3 triangles. For that coupler, use part# W11245707.

Do-It-Yourself Stories from Customers like You Microwave turntable motor overheated and melted tray coupler   Terry H. • Columbia , MO • May 31, 2018

Obtained the replacement motor and tray coupler from Appliance Parts Pro. Video of the typical replacement was very helpful to show what to expect and how to replace the motor and coupler. The removal of the bottom plate was held in place by several phillips screws. The motor was attached with two torx screws. The electric connection clips to the motor required needle nose pliers to pull them off. The tray coupler was simple to install after the motor was secured and bottom plate was replaced.. Read more

Microwave High Voltage Capacitor
Genuine Whirlpool part
By: Whirlpool
Part Number: W10850446

Microwave not heating or making loud humming noise? The high-voltage capacitor supplies power to the magnetron. DIY repair in under an hour.

Do-It-Yourself Stories from Customers like You My microwave was working at half power   Eric H. • Tonawanda , NY • October 30, 2015

I ordered a new magnetron and a new capacitor and after they arrived I set to work. I took plenty of pictures with my phone to remind me how the components came apart but it was pretty straight forward. Once the new parts were in and everything was reassembled the microwave worked good as new. The repair was less than a third the cost of replacement and no special tools are required. Just be careful to discharge the capacitor. This website is a great resource. Read more
