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 microwave magnetron is a critical component that generates the microwave energy needed to heat food. As a high-voltage tube, it converts electrical energy into microwave radiation for efficient and even cooking. If your microwave runs but does not heat, produces weak or uneven heating, or emits unusual humming, sparking, or burning smells, the magnetron may need replacement. Built for durability and precision, this part restores proper heating performance.
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.

Microwave not heating very well
Took microwave off the mount, removed all the outer covers except the face, used metal screwdriver to short the big capacitor to keep from being shocked, removed magnetron and replaced with new part. Put back together, hung on wall, and finished. I used a youtube video and it turned into a very simple fix.

Microwave not heating, working otherwise
This was an over-the-range microwave/hood, so the replacement parts were significantly cheaper than buying a new unit.
Take microwave down (really a two-person job). Remove microwave cover (about 20 philips screws), discharge HV capacitor by shorting terminals to microwave case. Take photos before pulling anything apart. R
... Read moreemove plastic ducting covering part of the magnetron (3 philips screws). Remove old magnetron (4 Torx screws), need to disconnect small thermostat on side (2 philips screws) and replace with new magnetron. Replace HV diode (screw on one end, other end simply plugged into capacitor terminal). Put everything back together and it works fine.
