If there is one appliance in the modern kitchen that makes life easy, it is the microwave oven. Since its invention in the year 1945, the microwave has been the go-to appliance to warm up leftovers, cook a quick meal, and even reheat a cup of coffee in the morning. If something happens and your microwave stops functioning, there is no doubt that you will feel like your kitchen is missing a crucial element. Here are a few of the most common problems that can come up with a microwave oven and what you will need to know to get this appliance back up and running.

Problem: The microwave's digital operation panel will not work at all.

Cause and Solution: The digital panel on a microwave panel will often quit working before anything else on the unit, simply because it is electronic and more prone to failure. Unfortunately, if the digital control panel stops working, the unit will not function at all as this is the central command center of sorts. It is almost always recommended that control panel replacement only be tackled by a licensed repair technician because it involves detaching the inner connections, which is a task in itself that can cause damage if you are not careful.

Problem: The microwave oven does not shut off when the door is opened.

Cause and Solution: Inside of the latching door of most microwaves is a sensor that relays a message to the timer when the door is opened, so it will stop running. If the microwave oven continues running after the door is opened, it is highly likely that the sensor inside of the latch has malfunctioned. Even though you can usually get the parts that you need to replace the sensor on your own, this can be a technical task that will involve dissecting the latch unit, which can get pretty complex. Therefore, most microwave owners will hire a technician to handle the problem.

Problem: The unit will run as normal, but will not supply any heating power.

Cause and Solution: Most of the time, lack of heat during operation is indicative of a fuse failure. The fuse panel is located behind the instrument or operating panel in most models, but is usually fairly easy to get to with the right tools. If you decide to replace the fuses yourself, be sure to unplug the microwave from its power source before you start.

With an appliance that fits in so seamlessly with your everyday modern life, it is easy to take its value for granted until something goes wrong. If you are having microwave oven issues that you cannot diagnose on your own, contact an appliance repair technician such as DBH Appliance Repair for advice.
