Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.
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
Microwave won't turn on or has no power? A blown fuse is often the cause. This safety component protects against electrical surges and short circuits.
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 not heating but still running? The magnetron controls heating function. DIY repair in under 2 hours with basic tools and multimeter testing.
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

The Switch, Micro is an OEM part for LG microwaves. This micro switch is crucial for the operation of the microwave door mechanism, ensuring that the microwave only operates when the door is securely closed.
Causes of a bad micro switch can include wear and tear from frequent use, damage due to electrical faults, or physical impact that disrupts its functionality.
Symptoms of a bad micro switch include:
This OEM LG part is also compatible with Sears/Kenmore models.
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
Replace your microwave's halogen bulb to restore interior and cooktop lighting. Recommended when bulb burns out from normal use. Verify fit by model number.
The replacement lamp fit perfectly. I had tried other replacement lamps from the hardware store but wasn't able to find one that would fit. The lamp socket on the microwave was slightly smaller than a standard bulb. Read more
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.
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
This factory screw secures appliance components to their mounting points. Replace missing, worn, or stripped hardware to restore a tight fit, proper alignment, and quieter operation across the affected assembly.
Ordered Bake Element, Y04100019 (Whirlpool AP4283614) to replace a broken bake element on my 30-year old Jenn-Air Model S125 Downdraft Slide-in electric range. Received the element very quickly but it had been damaged in shipping. Called AppliancePartsPros to report this and they quickly shipped another element - very easy process. To install the element, I turned off the power to the range, put on rubber gloves (just in case) and removed the two sheet metal crews at the rear of the oven -... Read more
Secures microwave to mounting bracket. Replaces stripped, cross-threaded, or missing cage nuts. Installs inside cabinet housing for stable installation.
I took the machine screws out of the outer panel for the right side only. Then pull the panel back a bit to release the lips from the front of the machine and had immediate access to the internal assembly that housed mounting nut. Order the new parts from AppliancePartsPro.com during the Thanksgiving week. Still received via FedEx in short time due to their same day shipping - which was greatly appreciated and surprising. Most small part places take a while to get the product out the door,... Read more
Fix loud noise, humming, or overheating in your microwave. This cooling fan motor restores proper airflow. Moderate difficulty repair with basic tools.
Looked online and found that someone had experienced the same issue and had replaced the cooling fan assembly for the magnetron. I ordered the parts for the assembly (motor, fan, and support), and replaced them and this fixed the problem. It took about 10 minutes to replace the parts, but lowering the unit and disassembly took around 45 minutes. The most difficult part was getting the outer sheet metal cover back on after the repair, as it has a bunch of clips on each front edge that need to... Read more
Microwave won't turn on or has no power? A failed thermostat often causes complete power loss. Moderate DIY repair requires disassembly to access.
I checked for the reasons there was no power to the microwave. Then I talked with the technician at AppliancePartsPros who stated that it was most likely a blown or defective fuse. My LG microwave has two thermal fuses, a fuse assembly with two prongs and a short (1 inch) barrel type fuse. I replaced all of them after viewing YouTube videos and then reviewing the diagram for my microwave on the AppliancePartsPrps website. That was very helpful in locating where the fuses were installed. It... Read more

I ordered the part (plus a couple general maintenance items). They arrived the next day - I was shocked! We fixed the unit and we were up and running in less than a day of the order. Great service. Read more
