If your microwave has stopped heating, the cause may be magnetron failure. The magnetron can get burned out if the unit is turned on when it is empty. A broken magnetron cannot be repaired, so if you experience this problem with your microwave you would have to buy a new magnetron in order to get your microwave working properly again.

If the microwave's door doesn't close properly, it can keep the unit from working if it thinks the door is open. The root cause of this common malfunction can be the door's hinges or springs coming loose. This can be a simple do-it-yourself fix that requires tightening any loose screws that you find when you investigate the problem. Otherwise, you can replace any damaged parts that are beyond repair.

There can be different reasons that your microwave is making noise. The easiest cause to diagnose and fix is a noisy microwave plate. If this is the issue, take a look at the couple and guide roller. Other possible causes of a noisy microwave include a faulty drive motor or magnetron. Other parts that could be causing the noise are the high voltage diode or the cooling fan.

The microwave light is out

The light bulb in your microwave allows you to see inside the unit while it is in operation. If the light won't turn on, the fix can be as simple as replacing a burned-out bulb -- but the ease of replacing the bulb varies depending on the model; some units require you to fully open up the case to replace the light. If the bulb doesn't appear to be the reason for the light not working, the issue is likely due to a malfunction with your microwave's control board.

The touchpad does not respond

If the electric touchpad on your microwave doesn't respond, you can't use the controls to operate the unit. A couple parts can cause an unresponsive touchpad. You can first check the membrane switch, which will allow you to check the responsiveness of individual buttons. If that doesn't seem to be the problem, the issue is likely with the control board.

When your microwave stops working properly, you may opt to buy a new microwave rather than fixing your existing unit or buying replacement parts for it. If you want a new microwave, be sure to check out Appliances Connection because we have a large selection to choose from.
