Symptoms of a saturated or clogged charcoal filter may include:
- Lingering cooking odors in the kitchen
- Reduced efficiency in capturing smoke or grease particles
- The presence of visible debris or discoloration on the filter
This OEM LG part can also be used on Kenmore/Sears appliances.

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...

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.

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!

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...

No power. William R. • Jacksonville , FL • February 12, 2019
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.

Microwave would not microwave Richard E. • Cape Coral , FL • January 05, 2020
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.
