Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):
This fuse, also known as a cartridge fuse, is a genuine OEM replacement part for microwaves. It has a glass cylindrical body with a metal cap on each end. The cap connects the fuse to the circuit. If the current goes above the fuse rating, the element inside the glass will melt and cut off the electrical current to the appliance. This protects the circuit and surrounding components from overheating and becoming damaged. Once the fuse is blown, the appliance will likely not operate at all, however, the fuse is designed to be easily replaceable. It is recommended to use insulated gloves and to avoid touching any exposed wiring connections. To replace the fuse, use a fuse puller to grip the metal caps and lift it out of the holder. Place the new fuse in the holder and ensure it is properly seated. Turn the appliance back on and check that the circuit is functioning.
How Buying OEM Parts Can Save You Time and Money
Why buy the real thing?
OEM stands for Original Equipment Manufacturer. Simply put, this means that the company who made your appliance is also supplying the replacement part for it.

Fuse replacement
Correct part, however, when installed and the microwave was powered up the fuse popped again. So, this confirmed that there was a major short circuit in the unit and it had to be replaced. I'll have better luck next time!

Fused
My fairly new very expensive microwave just stopped working. I did some research and found out that it could possibly just be as simple as a fuse. I found the part on your site it was a perfect match. It was easy to order and came in less than a week. It took about 30 minutes to do the job I microwave is as good as new.

Where is the fuse located and how do I get to it?
For model number LFMV1645TFA
Hello John, Thank you for the question. The Fuse is located on a fuse board on the right side of the unit behind the control panel. Once the power has been disconnected the microwave will need to be set on a flat surface. The vent grill and microwave cover will need to be removed to access the fuse located at the top of the right-hand side. The appliance will hold a charge that can be dangerous, even with the appliance unplugged. We advise to use caution. We hope this helps!

When I press the start button it turns off and flips the breaker. I flip the breaker back in it turns back on meaning it shows the time and the lights and exhaust fan still work fine. Problem is just when you hit the Start button it triggers the breaker to cut off.
For model number FFMV164lsa
Hello JoAnn, Thank you for your inquiry. We have researched the model you have provided and we would recommend checking the following parts to fix your issue: the fuse, the door switches, and the thermostats. You can test the parts with a multimeter. For safety reasons, since the microwave capacitor can still store electricity even when the microwave is unplugged, it is usually advised that you discharge the capacitor before any attempt at repair. We have included a link on how to do so.

My microwave stopped working. I put a 20 amp fuse in it and it worked fine, came rite back on. Today the fuse blew out again. What else could be causing this? Should I just get a new one?
For model number MWV150KWA
Hello Timothy, Thank you for the question. As long as the proper Fuse was installed, we suggest testing the the Door Switches and making sure they are properly seated in the holder. They can cause a sure that blows the fuse. If the Switches are good, you may have a defective Magnetron blowing the fuse. We hope this helps, good luck with this repair!
Microwave trpped circuit and now will not go on at all. I assume it is the fuse. How do I get to the fuse in this microwave?
For model number 790.80333310
Hi Sandra,
Thank you for your question. If your microwave is tripping the breaker, then it may not be plugged into its own dedicated circuit. Unplug from it from the electrical outlet where it is currently located and plug it into another outlet. If you turn it on and it does not trip the breaker, it was sharing a circuit with another appliance and it was too much for the breaker. If you turn it on and it does trip the breaker, then a part inside the microwave is causing the issue. You will need to inspect the fuse, the diode, the magnetron, the door switches and the capacitors. For safety reasons, since the microwave capacitor can still store electricity even when the microwave is unplugged, it is usually advised that you discharge the capacitor before any attempt at repair. We have included a link on how to do so. We hope this helps! If you have any questions, please let us know.
The front screen is not turning on, no display but the light turns on in the microwave
For model number FPBM3077RFB
Hello Ryan, Thank you for writing. This could be an indication the PC Board is faulty and may need to be replaced. We also suggest checking the wiring to make sure there is no damage and everything is secure. We hope this is helpful!
Is this 20 amp time delay fuse. I just replaced the fuse three days ago and it blew out yesterday.
For model number FFMV1645TH
Hello Frank, Thank you for contacting us. We have researched the model you have provided and have found the part you are looking for is PartSelect Number PS12071294 for the fuse, it is not a timed delayed fuse. If the fuse is blowing, you may have a faulty door switch. We hope this helps!
Trips the circuit breaker for microwave. The fan works, the clock works, but when I try to use it it immediately tips the breaker again.
For model number 790.80323310
Hello Richard, Thank you for the question. Normally this is an indication one or more of the Door Switches are defective and will need to be replaced. We suggest testing each switch to check for continuity. We hope this helps!
