Almost every American household owns a microwave – an appliance that can last a long time when properly taken care of.

Common microwave problems can be easily fixed by most owners, but it is essential that safety precautions be taken to avoid electrical shock or risk of injury.

Be careful and safe when repairing a microwave or another electronic products and household appliances. Always keep a first aid kit near by in case of injury and wear gloves to protect from electric shock. Unplug the microwave and all electrical equipment before starting work and use a voltage meter to ensure that there is no electricity left in the unit.

When trying to diagnose the problem with your unit or when looking for a correct part for your microwave, it is essential that you locate the model number of your appliance. The model number is commonly found in these places: on the back of the unit; inside the unit on the upper left side; on the side of the control panel; on the front edge of the microwave door.

These are some of the most common problems that can go wrong with your microwave:

  • Microwave units are equipped with line fuses – parts that act as protectors if there is a power surge. If your microwave stops working, first check the fuse to see if the fuse has melted or blown, and replace the fuse with a new part. Watch this helpful microwave repair video on how to check whether your appliance has a faulty fuse.

  • It is essential that the microwave door is properly closed when the unit is in operation, so there is a door switch located on the microwave door that ensures that the unit cannot run when the door is not closed. Sometimes this switch wears out or stops working and then the microwave controls think that the door is open even when it is closed. Both the microwave door switch and the latch connected to the switch break on occasion and require replacement.

  • The microwave touch pad is a delicate instrument that guides the operation of the unit. If there is a spill on the pad, moisture has been known to collect on the inside, and the touch pad can malfunction. Take the touch pad out of the microwave and let it dry or replace the part if necessary.

To minimize the number of problems and repairs with your microwave, do these easy maintenance tasks: clean the interior and exterior of your microwave unit at regular intervals or when dirty; make sure that the microwave outlet has surge protection; never run the microwave when empty, because that can damage the internal circuitry of the unit.
