Small appliance repair man fixing a microwave

A common staple in many homes, the microwave can be a lifeline for many households across London and the home counties. A good microwave can last many years before faults arise and with good maintenance and care, you can keep lower the costs and the increase the longevity. At Capital Repairs, we’ve put together the 5 most common microwave faults that people experience, so you can spot the signs.

If your microwave seems to be working fine, yet your food isn’t heating properly, it may be due to the issue of the magnetron. The magnetron is the component that generates the microwaves that heat the food. Another cause for a microwave to stop heating your food can be due to the microwave being covered and not being able to vent properly.

The turntable is the glass plate at the bottom of the microwave, which you would place your microwave-safe plate or bowl onto. The turntable rotates so that the surface of the food heats evenly. If your turntable doesn’t rotate, this could be due to a number of reasons including a problem with the motor, the turntable coupler, the roller guide and others.

To see sparks inside your microwave can be quite alarming. However, there could be an easy explanation. If there is any metal inside your microwave, this will cause your microwave to spark. Make sure that you use non-metal cleaning tools and microwave safe utensils/crockery. Another cause can be from damaged components, such as a faulty wave guide cover; this is a piece of the microwave that helps guide the heat waves.

Your microwave may seem like it’s working perfectly fine, however, the inside bulb doesn’t light up. There could be plenty of reasons why this is the case, including the simplest of the bulb running its course and burning out, in which case can just need a replacement. Another cause can be from the main control board of the microwave or even the light socket. These checks should only be performed by a trained professional.

Each microwave model is different and has different controls. However, they mainly fall into either manual or digital controls. Controls can stop working for a multitude of reasons, this can include a disconnection in the circuits, jammed components or damage. The first thing you should try and do is to turn the power off from the mains and then back on again. If there is a surface issue, for example, trapped food, clean with a lightly damp cloth whilst the power is off.
