Electromagnetic furnaces, which are common cooking equipment in modern kitchens, are highly efficient and accessible to consumers. However, when electromagnetic furnaces fail, how quickly and accurately to maintain them becomes a concern for many users. Common malfunctions in electromagnetic furnaces and maintenance methods are described below。
**i. Appearance check**
The first step in the maintenance of the electromagnetic furnace is to conduct a physical examination. Check whether the power lines are broken, broken or plugs loose or, if so, replaced or re-introduced. At the same time, the panels are checked for cracks, broken or stains. The stains on the panels can be wiped with a flexible cloth to extract a suitable neutral cleaning agent, and small cracks do not affect the use of the panels, which need to be replaced for serious damage. In addition, there is a need to ensure that the vent is free of dust, muzzles and can be cleaned with soft brushes or chillers。
**ii. Functional tests**
Functional testing is a key step in judging the failure of the electromagnetic furnace. Press the button of the electromagnetic furnace on a case-by-case basis to check whether there are problems of slow reaction, non-responsiveness or broken buttons. If yes, it may be that the key is damaged, the key barrier will be measured in 10,000 meters and the barrier abnormally replaced. The boiler is then placed on an electromagnetic furnace, with different power slots selected for heating and observation of normal heating. If this is not possible, it may be a failure of power tubes, whole-stream bridges, etc., and the resistance and voltage of the relevant components will be detected using a universal meter. In addition, it is necessary to see whether the display screen is normal for numbers, symbols and working status, and if abnormal, it may be a question of the display screen itself or associated circuits, check whether the screen line is loose and replace it if necessary。
** internal inspection**
An internal inspection is required if neither the appearance inspection nor the functional test reveal a problem. Turn off the power, pull out the plug, turn on the hood of the electromagnetic furnace, find the fuse and check if it melts. If the melting occurs, other components, such as power tubes, current bridges, etc., will need to be checked for short circuits before the same specifications are replaced. At the same time, checks are made for drum packs, leaks, burns and colour variations in resistance. The capacity of the capacitor and the resistance value are measured on a single scale, and anomalies are replaced. In addition, it is necessary to test the positive and reverse resistance values of the power tubes and the whole flow bridge using a universal meter to determine whether damage has been caused and, if damage has to be replaced in a timely manner。
The maintenance of electromagnetic furnaces requires a certain amount of electronic knowledge and skills, and if the operation is unfamiliar or uncertain, it is recommended to seek the assistance of professional maintenance staff。
