Microwaves are a life-saver for busy people and families who do not have the time or interest in cooking three meals a day every day. However, microwaves don’t last forever. If you have noticed that your microwave has started turning off in the middle of being used, we recommend that you troubleshoot by following these tips. If you end up in need of appliance parts please contact American Appliance Repair at 800-640-9934.
There May Be an Issue with the Keypad Membrane
If maybe that the keypad membrane is old and/or malfunctioning, which can activate the controls without you doing anything. Some membranes are heat activated so if your microwave is located above a stove it could be that the heat from the stove is affecting your microwave. If that is the issue then it can likely be solved simply by moving your microwave so that it is not above your stove.
In other instances in which the membrane is causing the issue, you may be able to take the membrane off and replace it. In other instances, it may be necessary to replace the entire control panel. You can look up info about your particular brand of microwave to determine what to do.
There Could Be an Issue with the Control Board
Think of the control board as the brains of the microwave. It is the place from which all signals are received and from which they are relayed. As a result, if there is an issue with your control board then there could be many potential symptoms – one of which could be that the microwave has turned itself off in the middle of working.
As is true of membranes, it may be that you cannot buy just the part of the control board that is not working but must instead buy an entire control panel and replace it. If you can get to the control board then you can replace it – but some microwaves have control panels that are sealed and self-contained. These, unfortunately, cannot be repaired and it is likely time for a new microwave.
You May Have a Stuck Switch
Another potential issue is that your switches are stuck. This may be the case if you have a light that won’t turn off, or the turntable in your microwave continues to move even when the rest is not working. This is not as serious as it seems, since neither of those parts uses heat-producing parts of your microwave. However, it will be aggravating and cause unnecessary wear and tear on your microwave.
