Microwave won't heat but runs normally? A failed magnetron is the likely cause. This part generates the microwaves that cook food. Moderate DIY repair.
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
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:
This OEM LG part is also compatible with Sears/Kenmore models.
Called AppliancePartsPros because of good experiencing diagnosing problem with a dishwasher repair. We definitely are modest income amateurs! Same excellent response to our questions. Three possible causes. Used easy search menu to fine replacement parts. Bought all three, knowing that if all not needed, the others could be returned (within 365 days) for refund. Replaced the capacitor successfully after calling to get more help with a couple of places where we got stuck. Oven now works... Read more
Replaces a cracked, chipped, or broken glass turntable tray inside your microwave cavity. Typically damaged during cleaning or accidental impacts.
Pretty easy fix. Took out 7-8 screws to remove cover for access to light. 2 were security type screws so I had to run to the hardware store to buy a special screwdriver. One screw to remove the bulb. Read more
Fix a microwave that runs but won't heat with this high voltage diode. Converts AC to DC power for proper heating. Typical DIY repair in under 2 hours.
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
Microwave won't start or runs only when door is pulled? Replace faulty door interlock switches. This 2-pack covers top and bottom switches. DIY repair.
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
Microwave not heating but still running? The magnetron controls heating function. DIY repair in under 2 hours with basic tools and multimeter testing.
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

Put a new one in. 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:
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
This Fan Blade is an OEM part for LG microwaves. It is a critical component designed to circulate air within the microwave, aiding in heat dissipation and ensuring even cooking.
Fan blades in microwaves can suffer from wear, imbalance, or damage due to regular use or accumulation of debris. A malfunctioning fan blade can lead to inadequate ventilation, affecting the microwave's cooking efficiency and potentially causing overheating.
Symptoms of a bad fan blade include:
This OEM LG part is also compatible with some Sears/Kenmore models.
Replaced with a new motor. Read more
Connects the turntable motor to the glass tray hub so it rotates during cooking. Replace this shaft coupler if it's cracked, worn, melted, or broken.
About 9 screws on bottom and 2 on the turntable. The most trouble I had was putting the bottom back on. Took about 15-20 min. Easy fix Read more
Microwave won't turn on or has no power? A blown fuse is often the cause. This safety fuse protects circuits from shorts. Requires cover removal to replace.
In addition to blown fuse; the fuse holder was melted at one end. Checked the unit to see if any part or wiring that would cause the issue, none was visible. Referred to wiring diagram included inside to identify components, including interlocks. All seemed functional. Bought replacement 20A fuse. Fuse holder no longer available so bought similar unit with 25A rating - little retrofitting. Put unit back together, and it's working so far. Wife is happy. Read more
Replace your burned-out microwave light bulb to restore clear visibility inside the cavity or over the cooktop. Confirm fit with your model number.
Microwave making a loud humming noise or won't heat? A faulty capacitor is often the cause. Requires cabinet removal and safe discharge. Restore function.
Replaced the Magnetron, Capacitor, and the Diode. Able to repair $1400 microwave with parts that cost $218.54. Thank you ApplianceParts Pros. Watched trouble shooting videos on Youtube and found that these parts needed to be replaced. Read more
Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:
Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great. Thanks for the advice and the cost of the parts. Read more
