Most often, it can be repaired quickly and inexpensively. But you will need highly qualified help. Do-it-yourself repairs can turn the simplest breakdown into a serious malfunction. It is better to call a specialist by phone or using the feedback form on our website. Our technicians leave at any time convenient for you from 7:00 to 23:00 daily. We do not have holidays, weekends or lunch breaks.
Blown fuse
This is the most common cause of failure. There are two fuses in the microwave oven. The first F1, the so-called network fuse, is located at the input of the 220 volt network voltage to the microwave oven. This is the belgium telegram data one that can burn out. In this case, the oven stops turning on and does not respond to pressing any buttons. First, you need to diagnose the microwave oven: remove the mounting screws from the back and open the protective panel. Do not forget to pull the plug out of the socket before starting repair work. Then you need to forcibly discharge the filter capacitor. To do this, its terminals are shorted (i.e. connected to each other) using an insulated wire.
Be sure to hold the wire strictly by the insulation. After this, check for voltage on the network filter board and check the serviceability of the microwave power supply wires. If there are no faults in this part, you should inspect the diode in the rectifier circuit of the power supply. Most often, it is this that causes the fuse to burn out with this type of failure. The fuse in the microwave oven should be checked for a break visually or with an ohmmeter, if necessary, replace it with a working one and analyze the causes of the burnout, in order to avoid a repeat of a similar situation, paying attention to various darkening of the radio elements, which indicate a malfunction in the microwave units.
