If you are purchasing a used microwave, you need to keep an eye on it for problems. Getting microwave repair quickly will help prevent further damage. To help you know what to do, below are three common problems you will find with microwaves.
If your microwave does not heat while it is running, this is generally due to a problem with the magnetron. This is because this part is what provides power to provide the heat the microwave needs. One thing that can cause this problem is running your microwave with nothing in it; this can cause the magnetron to burn out. If the problem is the magnetron, it will have to be replaced as this part cannot be repaired.
If there is no problem with the magnetron, the problem could be a faulty transformer or diodes. If there is a problem with the door switch, this can cause the magnetron not to turn on. Fortunately, all of these problems can be repaired.
Buttons Not Working
If you press the buttons on the microwave and nothing happens, there is a problem with the control panel. This panel may be damaged or may have become worn out. The touch pad may also cause this to happen.
If the control panel and touch pad are found to be in good condition, the main control board may be an issue. If it is the touch pad or control panel, these two things can generally be replaced. If it is the control board, however, you may want to consider purchasing a new microwave. This is especially true because the microwave you have is used. Replacing the control board can be expensive and may cost you more than your used microwave is worth.
Microwave is Sparking
If you see sparks coming out of your microwave while it is heating your food, you need to turn it off and unplug the microwave immediately. Do not turn the microwave back on until the problem is repaired by a contractor. If you continue to use the microwave, the sparks will damage the internal components.
In some cases, this sparking can be caused by a problem with the cover. The wires are connected to this cover. If the contractor finds any wires have melted or are burnt, they will replace the entire cover. This problem is generally due to the age of the microwave.
