Do-It-Yourself Stories from Customers like You Humming sound and burnt smell   Antonio F. • Miami , FL • June 08, 2018

I measured the resistance between the two connectors on the magnetron: should be close to zero ohms and it was. I measured between the same connectors and the metal case: should be mega ohms, it was 15k ohms. That is a bad, partly shorted unit. I also checked the resistance of the thermal cut off, which should be zero but was 10 ohms so I replaced. The HV diode is checked with a 9 V battery (YouTube checking microwave HV diode) and it too was bad. Make sure to take pictures as you disassemble... Read more

High-Voltage Capacitor (Microwave), 1-Piece
Genuine Whirlpool part
By: Whirlpool
Part Number: WP8184813

High-voltage capacitor for microwave ovens that stores and releases the electrical charge needed to drive the magnetron, restoring heating when the original capacitor has failed and preventing further electrical stress. What it does:

  • Stores high-voltage electrical energy used by the magnetron to produce microwave energy.
  • Works with the high-voltage transformer and diode; a failed capacitor can cause no-heat or reduced-heat conditions.
  • Common, widely accepted symptoms: microwave not heating, loud humming, arcing/sparking, or blown fuse.
  • Replacing a defective capacitor can stop repetitive electrical faults and protect other high-voltage components.
What's included: One high-voltage capacitor. Install notes:
  • Always unplug the appliance before beginning service and discharge the capacitor with an appropriate resistor or discharge tool.
  • Handle and test the component using insulated tools; capacitors can retain dangerous charge even when unplugged.
  • Verify correct part orientation and secure connections; use only the exact replacement specified by the manufacturer.

Do-It-Yourself Stories from Customers like You Microwave cut out while cooking all power lost including otr light and fan   Matthew J. • Bethel , CT • December 28, 2017
