  • Helps maintain safe operating temperatures around heat-sensitive parts
What's included: 1 fixed thermostat Installation notes:
  • Disconnect power before servicing; some appliances contain high-voltage components
  • Access location varies by model; note wire positions before removal and transfer one lead at a time
  • Reuse existing mounting hardware; ensure firm terminal connections and correct orientation
  • After replacement, confirm proper airflow/venting and normal operation

Do-It-Yourself Stories from Customers like You Humming sound and burnt smell   Antonio F. • Miami , FL • June 08, 2018

I measured the resistance between the two connectors on the magnetron: should be close to zero ohms and it was. I measured between the same connectors and the metal case: should be mega ohms, it was 15k ohms. That is a bad, partly shorted unit. I also checked the resistance of the thermal cut off, which should be zero but was 10 ohms so I replaced. The HV diode is checked with a 9 V battery (YouTube checking microwave HV diode) and it too was bad. Make sure to take pictures as you disassemble... Read more

Do-It-Yourself Stories from Customers like You Microwave blowing fuse for Magnetron / high voltage circuit (humming noise prior to fuse opening).   Keith G. • Houston , TX • April 27, 2020

Main Fuse did not open, only fuse for high voltage section was opened. Prior to the fuse blowing a louder than normal hum was heard from microwave for 1-2 seconds prior. Easy fix is the high voltage capacitor, so first checked the voltage across the capacitor terminals to ensure capacitor was discharged. Typically should be reasonably discharged within 30sec-1min assuming drain resistor is still in place. Removed the high voltage cap, and checked the capacitance and did not get a reading....

Latch Hook
Genuine Frigidaire part
By: Frigidaire
Part Number: 5304470548

The Latch is an OEM replacement part for Frigidaire built-in microwaves. Securely mounted to the top interior section of the microwave cavity door, the positive-locking latch holds the door safely shut during operation. Crafted from corrosion-resistant materials for extended use, the latch handle withdraws the hook mechanism with a simple pull to conveniently access food within.

Symptoms of a bad latch include:

  • The microwave door popping or falling open unexpectedly  
  • Difficulty closing or fully engaging the secure latch hook 
  • Wear signs like loose mounting points or a worn handle

Causes can involve repeated opening/closing cycles gradually loosening mounting fixtures, or parts rendered ineffective by moisture intrusion over time.

Replacing this Frigidaire OEM latch prevents potential microwave door opening during cooking cycles. Compatible with Electrolux, Gibson, Kelvinator, and Kenmore built-in models.

Do-It-Yourself Stories from Customers like You Microwave shut off without usual beep at end of cycle no power to unit even though plugged in.   James B. • Rocky Hill , NJ • November 17, 2017

Replace Thermostat on top of cavity. The thermostat is attached via 2 bending sheet metal tabs. Ours blew because the two wires connected to thermostat shorted, connectors melted. The short was caused by buildup of grease under thermal wire cover, shorting both leads. The unit is used heavily. This is the first thermostat to go. I had to replace wire connectors that connected to thermostat as well since the connectors were melted as well. Helpful hint. The grease build up was probably caused by... Read more
