A microwave has a cavity magnetron inside of it that fires electrons at speed in a magnetic field that pass over cavities quickly. For example if the item should be cooked for five minutes for.
Take special caution to not touch the two probes together.
How to test a microwave magnetron. Simple way to test your microwave magnetron comparing a bad one with a new one. How to test microwaves magnetron 1. Method 1 In this method you will first need to unplug the microwave oven from the main power supply and discharge.
Easy Appliance Parts recommends two tests you can conduct to figure out microwave magnetron issues. For the first test you need to locate where your microwave magnetron is and label the wires that are attached to it. Labeling these wires will help you if you need to replace a wire.
After you mark the wires youre going to set your ohmmeter to the lowest resistance scale. Touch one of the meters probes to a magnetron terminal. Touch the other probe to the metal magnetron housing.
Take special caution to not touch the two probes together. This could result in an inaccurate reading. This test should produce a reading of infinity - indicating an open circuit.
For more information about microwave magnetrons. BE CAREFUL BEFORE TOUCHING THE MAGNETRON AND BE SURE THE MAINS IS DISCONNECTED AND ALL CAPACITORS DISCHARGED Unplug all the wires from magnetron carefully and take note for the connections as the wiring is critical. Now with the multimeter set on LOWEST resistance range check both terminals resistance should be less than ONE Ohm Ω.
Now select the meters HIGHEST resistance range and check. In this video I will show you step by step procedure through which you can easily replacing Strong Magnet in Microwave Oven Magnetron—–. Disconnect the two wires going to the magtube and set it for 20-30 seconds and run it.
This amperage test is quick easy accurate and safe. Place a cup of water in the microwave. Attach your amp probe to the line splitter plug in and run microwave 10-20 seconds.
Proceed as for JIS test but with water at 10 C - 2 C On reaching step 5 multiply the difference between the averaged values by 7115 to give the power output in Watts IEC705. You can test your microwave oven with food. Anything that is prepared or has package instructions is an excellent candidate for this test.
Cook the food according to the instructions on the package. For example if the item should be cooked for five minutes for. If your microwave is making an unusual or loud humming noise you may have a problem with the magnetron.
This component is part of the high voltage circuit and provides the microwaves that generate the heat. If the magnetron is defective it may cause a loud humming or buzzing noise. Subsequently question is Is a noisy microwave dangerous.
If your microwave is loud noisy or making unusual clicking sounds it could be a result of a defective magnetron. This test is to check between the terminals of the magnetrons with an ohmmeter. Before testing you need to unplug the power terminal of the microwave oven.
By attaching the ohmmeter the continuity of the resistance should be infinity. If the reading is other than continuity then there is something wrong with the magnetron in your microwave oven. So what is a magnetron in microwave oven technology.
A microwave has a cavity magnetron inside of it that fires electrons at speed in a magnetic field that pass over cavities quickly. This generates microwaves that are channeled into the microwave oven. These microwaves excite water molecules in food creating heat which cooks food quickly.
So a microwave oven uses a magnetron to cook food.
