Do-It-Yourself Stories from Customers like You Kennmore elite microwave with f5 error code   Julius D. • Oxford , PA • February 11, 2017

When Microwaving food, the display panel would seem to act normal, but the typical microwave sound would be absent. No microwave action would occur. Eventually an F5 code would display. Problem was the upper door switch. Found it by opening up the cabinet, removing the display panel (1 screw and a couple of plugs) and testing all three micro switched with a meter. Two switches are for the door and one for some kind of ventilation flap. They are all in the same area. Go to YouTube to see... 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
  • Won't start

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

Do-It-Yourself Stories from Customers like You My jenn air microwave developed a loud hum and no longer heated anything   Jared B. • Norfolk , VA • October 04, 2014

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. To replace my microwave with a comparable model would have cost at least $800. The diode and magnetron cost around $170. I watched a few videos on YouTube demonstrating how to do the repair safely and I felt like I could do it. I ordered the parts on a Monday evening and had them Wednesday.

Do-It-Yourself Stories from Customers like You 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" &... Read more

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
