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
  • Won't start

Genuine Lg part

Part Number: 4970WRA001G

Microwave door won't stay closed or latch? This door latch spring provides tension to secure the door shut. DIY repair in under 10 minutes with video help.

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 maytag mmv4205bab over the cooktop mounted microwave stopped heating without any warning the unit sounded like it was working but now the sound was noticeably louder i had replaced a magnetron   Lee B. • Lakewood , CA • February 27, 2015

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 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... Read more

Microwave won't heat but hums loudly? The diode regulates power to the magnetron. Test with multimeter—reads one direction only. Moderate DIY repair.

Do-It-Yourself Stories from Customers like You Loud hum/buzz & no heat   Greg S. • Springfield , VA • November 30, 2015

Replacing a magnetron in my particular 9-year-old microwave (a microwave/hood combination) was not a simple “plug & play” operation. That is why I am placing this in the slightly difficult area. First, it takes 2 people to remove the microwave from the top of the stove. Next the main outer panel need to be removed. After that, 2 sheet metal panels need to be removed in order to expose the high voltage components for testing. Always discharge the high voltage capacitor first before doing... Read more

Do-It-Yourself Stories from Customers like You My microwave vent grill kept falling on my head when i opened my microwave   Christopher D. • Kernersville , NC • February 23, 2015

Well, I gotta say I was happy to find you still had parts for almost 20 year old microwaves. The microwave itself worked fine, so I hated to have to buy a new one, but I just couldn't take being hit in the head anymore; and my fix of using string and wire to tie it to the surrounding cabinets was unsightly to say the least. I'm glad I did some research and found this part - all I had to do was pop it in place and now the vent grill is secure. Problem solved with minimal cost. Read more

Do-It-Yourself Stories from Customers like You Smh1816s samsung microwave went completely dark no controls no lights receptacle good   John S. • Olathe , KS • March 17, 2015

I attempted to diagnose the four thermostats/thermal switches in the microwave....two right behind the control panel, one on top of the cooking cabin, and one under a metal shroud above the magnetron. While checking continuity with a voltmeter, i questioned one of them behind the control panel and the one above the magnetron. I then noticed a burn mark on the plastic connector sleeve for the one above the magnetron. I took a scrap piece of 14 gage copper wire and beat the ends flat with a... 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. The only difficult part of... Read more

When the new bulb didn't want to go in, I felt around and realized the base of the old bulb was still in there. With some effort I got it out and new bulb in, Light cover fit fine, but did not come with a screw to hold it in. That would have been helpful. Read more
