Do-It-Yourself Stories from Customers like You Didn't heat.   Harry W. • Maple Park , IL • January 21, 2018

My son told me that almost all the microwave ovens that came into the repair center he worked at, 15 years ago, had a defective magnetron. I ordered a magnetron, and sat back until one shipped. The one that came, the first time, was in a small factory cardboard box, which was in a large bubble-pak Fedex envelope; which didn't show any signs of abuse. Inside, however, the factory box was beat up. Removing the magnetron, I noticed that the socket, as well as its' pins, was bent, and loose in the... Read more

Time Delay Fuse
Genuine Lg part
By: Lg
Part Number: 3B74133Q

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

  • The microwave not turning on
  • No response from the microwave control panel
  • The microwave stopping unexpectedly during operation
  • Electrical issues or blown circuits in the microwave

This OEM LG part is also compatible with Sears/Kenmore models.

This part fixes the following symptoms

After dismounting the unit from its wall-hanging bracket, the most tedious part of the repair was removing over a dozen screws holding the cover in place from the top, bottom, and both sides. Fortunately, I had placed the unit on a bench that allowed me to slide the unit allowing access to the screws on the bottom edges of the unit. Always discharge the capacitor before continuing to work on the unit by discharging the capacitor by shorting the contact without the diode to ground. Access to the... Read more

Do-It-Yourself Stories from Customers like You Microwave would say "cook" and timer would count down but turntable would not rotate and magnetron did not turn on   Kathy K. • Athens , GA • January 12, 2016

Checked the three door switches; used ohm meter to see if there was resistance or if a switch was bad. 2 out of 3 switches showed resistance with the ohm meter. The last one tested (of course the last one) NO (normally open) did not show resistance; I.e. the ohm meter reading did not change when the switch was depressed. Appliance parts pros was the only company that had the same model number I was looking for (SZW-V16-FD-63). I ordered the relay switch, 2 days later it arrived (regular... Read more

Do-It-Yourself Stories from Customers like You Lg microwave door would not latch closed   Audrey S. • Rochester , NY • February 05, 2018

Ordered door latch part and new spring. You Tube video helped me identify what I needed. I tried the fix recommended and it didn't work so I ordered the parts. It took less than 5 minutes to switch out the old for the new. If the door doesn't latch, you can't run the microwave and it's key. It wasn't an expensive or hard fix to get my microwave up and running again. So pleased with AppliancePartsPros for having what I needed and being reasonable about pricing. Turnaround time was excellent! Read more

I am not an appliance repair man. I am a general surgeon. I went online and researched the problem. The consensus was that my magnetron and diode were the most likely culprits.

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).

Do-It-Yourself Stories from Customers like You Our microwave made a "pop" sound and stopped working/   Daniel D. • Chesterfield , MO • September 12, 2020

I have a multimeter so I was able to check the fuse per website recommendations and it was blown. However, the capacitor on the microwave was also original so I elected to replace the capacitor, fuse, and the ground protect diode. The repair was very simple (making sure the capacitor was discharged before replacing) and the microwave is now up and running again. Excellent trade to buy $40 worth of parts rather than a new $400 microwave. One nit - Kenmore puts a screw in the back that... Read more

Do-It-Yourself Stories from Customers like You Microwave had no power and no lights   Matthew H. • Rocky Hill , CT • October 25, 2016

I have a Jenn-Air microwave that didn't turn on and had no lights. It just stopped working completely. I unplugged the unit and had to remove the rear cover using a *security screw kit* that prevents people from opening the rear panel. Once opened, I removed the fuse and testing it with an OHM reader to determine that the fuse went bad. But I also had to determine why the fuse blew and noticed a sticky oily substance under the Capacitor. I used a rubber glove and needle nose pliers to... Read more

Microwave Door Switch (Interlock Microswitch)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP3405-001034

This door interlock microswitch detects when the microwave door is fully closed and allows the unit to run only under safe conditions. Replacing a worn switch restores reliable starting and consistent operation tied to the door latch.

  • Monitors the door-latch position and completes the safety interlock circuit when the door is closed
  • Helps prevent operation with the door open
  • Common symptoms: microwave won't start or stops when the door is moved; requires pushing/jiggling the door to run
  • Contributes to "runs but no heat" or light/fan behavior that changes as the door is opened/closed
What's included: One door interlock microswitch Install notes:
  • Unplug the microwave before service; internal high-voltage components can retain a dangerous charge
  • Access the switch at the door-latch assembly; transfer wires one at a time to the new switch to maintain correct positions
  • Ensure the actuator aligns with the door latch and that the switch clicks freely when opening/closing the door
  • After reassembly, test with a microwave-safe cup of water to ensure proper operation
Note: Many microwaves use multiple door switches; each is sold individually.

This part fixes the following symptoms
  • No heat

Utilized a YouTube video to isolate the door switches as the issue. These were easily identified following the isolation process and simple testing. I ordered a door switch and secondary switch on Monday and they arrived on Tuesday via FedEx. 15 Minutes to re-install, re-assemble cover and the unit was working fine. A very good experience with parts availability and shipping. Read more
