F1e5 error code James C. • Clifton , TX • May 13, 2015
Replaced numerous items including this Inverter and two control boards but the Magnetron was the ultimate solution. The tip was clearly burned through when I removed the original.

Kitchen aid architect ii microwave turntable stopped rotating Stephanie M. • Colorado Springs , CO • March 25, 2017
First, it was going to cost $95 for an appliance guy just to look at it! I figured there would be an upcharge on the parts + labor on top of the $95, so I took a chance & decided my husband & I could fix it cheaper; we were right, but it was a 3 week process (luckily, we have another microwave in the basement we were able to use in the meantime). I googled the microwave model #, then price checked the same item I thought we needed; printed off the diagrams of the various microwave "systems" &...

Microwave blew line fuse Gerald G. • St. Louis , MO • August 05, 2019
It took a long time to determine the problem but eventually I discovered that the plastic bracket (latch hook) that held the three door-switches showed appreciable wear from repeated door openings and closings. This wear stopped the door from sealing properly and the door switch safety mechanism blew the line fuse. I replaced the worn bracket (AP6230612) as well as the plastic latch mechanism (AP4553585) on the door that engages this bracket (and of course the fuse too) and the microwave now...

Interior light and turntable failed at the same moment. Stacey B. • New Bern , NC • February 01, 2021
Knowing the odds of 2 failures occurring at the same exact time was unusually high, I just searched your site for what other broken items might affect these two failures. Came up with next control item upstream and tallied that item failure with percentages of successful repairs, (4 mins.) door safety switch.
Since I had to change out the most likely of the 3 and since I was already was going to be into the switch panel I ordered all 3 and swapped them all out to cover my butt, as they were...

Genuine Ge part
By: Ge
Part Number: WB24X10204
This microswitch senses the microwave door position and controls the safety interlock circuits. Replacing a worn switch restores proper start/stop behavior so the oven only runs when the door is fully closed.
- Detects door open/closed status to enable or disable cooking
- Part of the safety interlock system that stops operation if the door opens mid-cycle
- Replace if the switch fails a continuity check or shows heat or terminal damage
What's included: 1 microswitch
- Disconnect power before service; microwave capacitors can retain a dangerous charge
- Note wire positions and move them to the same terminals on the new switch
- Ensure the door latch cleanly actuates the switch; test operation before reassembly

Genuine Frigidaire part
By: Frigidaire
Part Number: 5304493153
The Door Switch is an OEM replacement part for Frigidaire wall ovens. It is a component located on the oven door that detects when the door is opened and closed. The door switch works alongside the control board to regulate oven operations based on door position.
Symptoms of a bad door switch can include:
- Oven failing to automatically go into bake or warm modes after door closure
- Interior lights not turning on when the door is opened
- Control buttons/display remaining constantly lit instead of dimming
- Oven not heating or functioning properly in different modes
Causes relate to normal wear over extended use as the door switch mechanism cycles with frequent door openings and closings. Moisture exposure or impacts could also degrade switch performance.
This OEM Frigidaire switch is compatible with Amana, Jenn-Air, KitchenAid, and some Electrolux wall oven models as well.

Frigidaire microwave oven lights and timer work but oven doesn't heat Reese F. • Essex Junction , VT • August 16, 2015
I diagnosed this problem via the web and the advice was spot on. The problem was a failure of the bottom door switch. I used a multimeter to verify that the switched never closed properly. It took me a minute to figure out how to remove the old switch (press a release tab under the switch while simultaneously rotating counter-clockwise). That was about the most difficult part of the repair.

The micro switch on the door clasp failed second time in 10 years John P. • Mcdonough , GA • June 23, 2018
Checked on AppliancePartsPros and found the parts, once I received the parts I pulled the outer cover of the microwave and replaced the three switches. For the price of the three switches it was cheaper to install all new. Total repair time, 15 minutes. Microwaves back up and running.
Very easy fix.
