FUSE – Part Number: 5304509451
$21.95
In Stock
FUSE

(9)
Part #5304509451
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.

Wave Guide Cover

(9)
Part #5304509435
This OEM waveguide cover in your microwave is a heat-resistant component that prevents food, grease, and moisture from entering the waveguide. It is typically located on the side or top wall of the cooking chamber. If the cover is broken, you may notice cracks, charring, or burns, and potentially see arcing or sparks during operation. Not replacing a damaged cover can lead to short circuits and the risk of electrical components touching your food. To remove the cover, start by disconnecting the microwave from its power source before opening its door. The waveguide cover is slotted or snapped into place, so gently slide or apply pressure to release it from the clips or slots. Please note that the cover is sold individually.

Part #5304509459
This door switch is designed for use with various makes and models of microwaves and is a genuine OEM part. This individually sold switch connects to the frame of the microwave through the door switch holder, which will need to be removed completely in order to replace this switch. If your microwave will not start, displays error codes, or if the door will not shut properly and the inner light stays on, the switch could have broken from use and is in need of replacement. Due to the high voltage used within the components of microwaves, take extra caution when repairing your microwave. To replace the door switch in your microwave, disconnect the microwave from the power, and use a flat-head screwdriver to gain access to the switch through the main control panel.

Switch Holder
Part #5304509457
A loose door, repeated clicking, or intermittent operation can indicate a damaged latch body or switch holder. The housing aligns the safety switches with the door hooks and helps prevent operation while the door is open. First inspect the latch opening, door alignment, mounting tabs, and switches to identify every damaged component. Match the replacement to the microwaves full model number and verify what the assembly includes. Unplugging does not remove the high-voltage capacitor hazard, so professional service is recommended. Do not test the appliance with covers removed or safety interlocks bypassed.

The Breaker Trips each time the start button is pushed. Not sure which switch needs to be replaced. Top,Middle or Bottom. Thank You
Chris Boyle Profile
Hi Glenn, thank you for contacting us. This issue might be caused by a faulty door switch. We would suggest checking all three door switches to make sure they are seated properly and checking the continuity with a Multimeter to identify which switch is causing the issue. The part number for the top and bottom switch is PS12071303, whereas the middle switch is part number PS12071302. We hope this information helps!

Most of the control panel lights are out, what is the part I need. Is the panel need to be replaced
Chris Boyle Profile
Hello Hector, Thank you for your inquiry. If you have already tried unplugging the microwave for 15 minutes to see if it resets the control board and the issue is still happening, then we would recommend replacing the complete panel or just the control board. We hope this helps you.

Kamala - For model number FFMV1645TSA
February 10, 2020
Hi , we have this model of microwave , which was provided when we bought house 19 month ago but now when i turn on , it is automatically turn off from breaker, and when i turn on from breaker , and start microwave , turn off by itself. I don’t know what is wrong with that . Can you please help us ? Thank you.
Chris Boyle Profile
Hello Kamala, thank you for your question. The issue could be with the fuse PartSelect Number: PS12071294 and diode PartSelect Number: PS12071314. Those are the two parts we would recommend testing first. If those parts are ok, the issue could be with the door switches or the main board. We would recommend testing those parts next. I hope this helps.

Microwave keeps tripping breaker when i push,start button, i replaced all three door switches and holder.Thanks cliff
Chris Boyle Profile
Hi Clifford, Thank you for your question. If your microwave is tripping the breaker, it may share the same circuit with some of the other appliances in your kitchen. Plug it into a different electrical outlet and see if the breaker trips. If it does not, then you know it was sharing the circuit with another appliance. If it does, then there is a part inside the microwave that is malfunctioning and causing the breaker to trip. You will need to check the magnetron, the diode, the fuse, and the door switches. 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, https://www.partselect.com/Microwave+discharge-capacitor+repair.htm. You will also find information on how to test these parts under Free Repair Help and Instant Repairman on our website. We hope this helps! Good luck with the repair!

Remove vent cover then remove touch screen control panel. When you remove control panel take photo of where everything is plugged in then unplug and remove control panel. 3 door switches located next to door in a plastic chassis. Test each switch with current tester. Remove the bad switch and replace with the new one. You tube DIY helped.

First thing I dir was search YouTube for any related videos and found this one https://www.youtube.com/watch?v=uHj4H9Fdxrc, it was the exact problem my microwave was exhibiting. Once I verified the problem by troubleshooting, I removed the part and verified that the switches were working fine, the door latch assembly showed signs of wear which was the cause of the problem. After receiving the replacement part I installed it, verified that power was restored to the unit and reassembled the microwave, works fine, hope it lasts a long time!

The diagnosis is about an hour. Coz, I need to open the control panel, got a tester, and trsted all critical parts inside the panel.
Also, replaced the fuse just to make sure its a new one. Found out it was a switch (bottom part) that control the open/close of the microwave door.

When found out the problem, the rest of t he work is easy.
