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
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:
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
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.
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
This is a micro switch that detects whether the microwave door is properly closed and latched. It is part of the safety interlock system that prevents the microwave from operating with the door open. Replace this switch if the microwave does not start when the door is shut, runs with the door open, blows a fuse when the door closes, or stops mid-cycle intermittently.
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 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
Fix F4 error codes or sensor cook failures with this microwave humidity sensor. Restores automatic cooking cycles. Moderate DIY difficulty.
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
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:
Microwave not heating or sparking inside? This high voltage capacitor stores power for the magnetron. Common repair taking 30-45 minutes with care.
This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:
