Our Whirlpool microwave suddenly died. After troubleshooting, I discovered that the magnetron tube had failed. It also damaged the output transformer, capacitor, and the diode in the process. Of course, the fuse had blown. I happened to have one spare, which I installed and immediately ruined......I wasn't sure where I'd get replacements then thought, "Of course... Amazon!" Yep. There they were at an excellent price and ready to ship.These OEM fuses arrived after a few days with everything else. I installed the parts in a just a matter of minutes and I'm happy to report that our microwave works better than it had for at least a year.These Slow-Blow Microwave fuses are a great value. Very easy to install with NO problems at all. Great seller, excellent product, and very fast shipping! I highly recommend this seller.
