Procedure if there is no heating Fuse malfunction

The fuse prevents the device from breaking down due to power surges in the network, and the thermal relay ensures that the system is completely switched off when the door is open. Both can fail, but replacing them is quite simple.

It is also worth checking the voltage in the network and the number of devices connected to the socket. The microwave oven is very demanding in terms of power supply, so its minor deviations can interfere with the operation of the device.

Most models suffer from common problems and have similar, typical faults. For example, if the microwave works but does not heat, this indicates a faulty capacitor, diode or magnetron. To repair a microwave oven yourself, you will need a simple set of tools: pliers, nippers, a screwdriver, an adjustable wrench and a five-mm spanner, as well as a soldering iron with the necessary inventory.

When repairing a microwave oven yourself, you should remember about safety precautions. The two most important factors that pose a danger when repairing a microwave oven are high voltage in the oven's units and microwave radiation. Do not turn it on if the door lock is faulty or the mesh on the viewing window is damaged. Do not make holes in the body australia telegram data or insert any conductive objects into the oven's units and elements. Never touch the internal parts and units while the microwave oven is operating. Be sure to use a tester or other electrical measuring devices to measure direct and alternating current.

If the above reasons are not confirmed, then you need to disassemble the device to find the faults. Before doing this, you must turn off the oven from the network and wait a couple of minutes.

First, the primary winding is checked, for which the norm varies from 2 to 4.5 ohms. For the secondary winding, the limits are 140 and 350 ohms.
