Microwave runs but will not heat

Issue description:

The most common problem is that the microwave works, but does not heat. There can be many reasons - from banal incorrect operation to serious breakdowns. We will figure out what to do in each specific case, and how to fix the equipment. The most common reasons for the failure of technology to perform its direct functions are quite commonplace and are based on improper operation of microwave ovens. Several points can be highlighted here:

heating dishes together with metal objects

heating dishes in unsuitable dishes - for example, with a gold border or a tight lid - cheap and low-quality equipment - manufacturers deliberately do so to buy a new easier and cheaper than fixing old parts and wear and tear from time to time.

Solution:

To understand why the microwave has stopped heating and how to fix it, you need to understand the device.

Microwaves, namely, high-frequency radiation that heats food, is created by a magnetron. It is connected to the camera by a rectangular waveguide, which, in turn, can be covered with a mica plate or a plastic cover.

Power supply is provided by a transformer, which is assisted by a multiplier consisting of a diode and a capacitor. A fuse protects equipment from overloads and short circuits. The fan cools the magnetron and drives warm air into the chamber, which speeds up the heating of the food.

You can set the mode and time for heating food on the control panel. It can be both mechanical and sensory.

Does the microwave oven spin the disc, but does not heat the food? In addition to the lack of heating, pay attention to additional signs - for example, the microwave is buzzing or making a lot of noise.

First of all, it is worth looking at the instructions, since there are collected tips that can help to understand the causes of equipment malfunction. But the main problems are similar, so we will analyze them. Let's start with the simplest breakdowns that can be corrected at home.

The required voltage in the network for the correct operation of the microwave is 220 V. If this figure is lower even by 5-10 V, then the equipment will heat poorly, weakly, or every other time - depends on the magnitude of the voltage. In order to prevent such surges, it is necessary to install a voltage stabilizer.

Another option, in which a lack of voltage may occur, is to connect large household appliances like a refrigerator or washing machine to the same outlet, or even use a double / tee. Such actions are unacceptable, since the microwave oven must have its own free socket.

It so happens that the problem is not in the microwave oven itself, but, for example, in a wire or outlet. To make sure that this is exactly the problem, you just need to connect the equipment to another outlet and carefully inspect the cord. If problems are found, either the plug or the cord must be replaced. If you need help with microwave repair San Jose, call us right now!
