  • After replacement, confirm proper airflow/venting and normal operation

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

  • If the new fuse blows again, inspect the heating system, thermostat, venting, and airflow for faults

Do-It-Yourself Stories from Customers like You Our son tried to do us a favor by using the selfclean feature on our oven while we were out of town this caused one or more internal fuses to blow   Daniel A. • Magnolia , TX • May 13, 2017

Not sure which fuse might be bad, I ordered all three. The oven is almost twenty years old, so I figured it couldn't hurt to replace them all. The breakers marked oven were tripped, so we figured everything was off. Wrong! The 220 and the 120 are separate breakers. We found this out the old fashioned way, we got shocked. Anyway, the fix is pretty simple. Take off decorative trim. Only one screw on each side holds it on. Remove four screws securing oven to cabinet, and slide oven out. Our oven... Read more

Genuine Whirlpool part
By: Whirlpool
Part Number: WPW10638608

This protective fuse safeguards the appliance's electrical circuit. When an overcurrent or short occurs, it opens the circuit to cut power and help prevent damage. Replacing a blown fuse can restore power once the underlying issue is corrected.

  • Opens the circuit when current exceeds its design limit or a short is detected
  • Helps protect control and other internal components from electrical damage
  • Typical symptoms of a failed fuse include no power, dead display/controls, won't start, or immediate power loss
  • An underlying electrical fault is likely present and should be diagnosed
What's included: 1 fuse Install notes:
  • Disconnect power at the breaker or unplug the appliance before servicing
  • Replace only with the exact type and rating specified for your model; never bypass or upsize a fuse
  • Inspect wiring and components for the root cause of the blown fuse before restoring power

The same thing happened about two years ago and when I took off the back cover, the high limit switch was melted and crumbling, so I replaced it and it's worked fine until a couple of weeks ago. We smelled a stinky electrical burning smell a couple of times and then it stopped heating past 250 degrees. Turns out the high limit switch was crumbling again. This time I replaced both the high limit switch and the bottom element and it heats up again like it should to any temperature. One of the... Read more
