By: Frigidaire
Part Number: 5304509451

Microwave won't start or is completely dead? This fuse protects against electrical overload. Requires disassembly to access. Often replace with switches.

Do-It-Yourself Stories from Customers like You The frigidaire microwave would blow fuses on a regular basis   Loren A. • Windsor , WI • November 28, 2020

After doing some research the problem appeared to be the door safety switches. I ordered 3 new ones to replace all the original ones. Some minor disassembly of the microwave front was required to reach the fuse and switches. To reach the switches the control panel wires needed to be unplugged and the panel removed. After doing that replacing the switches was pretty strait forward. As of this comment the microwave has worked for 5 days without blowing the fuse so far. This has probably fixed the... Read more

Genuine Frigidaire part
By: Frigidaire
Part Number: 5304509457

The Latch Hook is an OEM replacement part for Frigidaire microwaves. It is an internal component that helps securely latch and lock the microwave door during operation.

  • Leaks of microwave energy from around the door seals
  • Error codes related to door-latching problems

This OEM Frigidaire replacement part is also compatible with Electrolux, Westinghouse, and Kelvinator microwaves. 

Do-It-Yourself Stories from Customers like You Microwave blew line fuse   Gerald G. • St. Louis , MO • August 05, 2019

It took a long time to determine the problem but eventually I discovered that the plastic bracket (latch hook) that held the three door-switches showed appreciable wear from repeated door openings and closings. This wear stopped the door from sealing properly and the door switch safety mechanism blew the line fuse. I replaced the worn bracket (AP6230612) as well as the plastic latch mechanism (AP4553585) on the door that engages this bracket (and of course the fuse too) and the microwave now... Read more

Do-It-Yourself Stories from Customers like You Re routing microwave exhaust   Karissa B. • Brookhaven , GA • October 19, 2015

We bought a house with an over-the-range microwave, which just recirculated air into our house--not effective for smoky meals! We removed the microwave and cut a hole to send the exhaust out the back of the microwave (and out of our house), but realized we were missing this damper and frame that go on the back of the microwave for rear exhaust. The parts fit perfectly and now we can enjoy a smoke-free kitchen! Read more
