After the microwave was invented in the 1940s, families began cooking a variety of foods in a fast and efficient manner. Over the years, the microwave was given new technological features and useful upgrades. Although the latest devices are more reliable, the directional couplers or other important components can malfunction. If this happens, you’ll need to seek professional repair services. The process of determining when repairs are needed can be somewhat of a challenge. However, there are five signs that mean that a microwave is about to fail.
Whenever certain components begin to spark, the unit has a serious electrical problem. You shouldn’t try to resolve any wiring issues without professional help because a microwave produces a high voltage. As a result, if you only touch one of the wires slightly, you’ll experience a major shock.
If your food is cold when you take it out of the microwave, the magnetron may need to be replaced or repaired. By conducting the two-minute test, you can easily determine whether or not the magnetron in your unit is failing. To begin, pour cold water into a microwave-safe mug. Then, heat the mug in the microwave for two minutes. If the water isn’t steaming when the microwave stops, the magnetron is failing.
All microwaves rely on different circuitry while in use. The circuit board that’s inside the unit is wired to specific components along the front panel. If a circuit malfunctions, the touch panel won’t operate properly.
A microwave shouldn’t make any buzzing noises when it produces heat. Usually, load sounds happen when the turntable is damaged. If the turntable isn’t cracked, the magnetron, capacitor, or power diode may be causing the problem.
Strange odors typically fill the air when a microwave has an electrical wiring issue. If the odor is strong, something in the unit is burnt or has melted. In these situations, you must shut off the microwave immediately and seek professional repairs.
Overall, since a microwave has a lot of advanced components, a professional repair technician must tackle any repairs that involve circuitry and wiring. Microwave technicians never cut corners because safety is always a main priority. They ensure reliably and customer satisfaction by using proper replacement parts that are designed for specific kinds of microwaves.
