The common question is how can we solve the many problems of repairing the electromagnetic furnaces by burning them, not heating them, and all kinds of failure codes? How can we fix them if they're broken? Non-cleaning of domestic appliances for extended periods of time may lead to increased electricity consumption, reduced useful life, functional disorders, short circuits, burning of electronic components and even fires. So we have to learn to be pre-prevent, to use electrical appliances properly, to understand the internal configuration of the electromagnetic furnace and to avoid accidents in case of damage to the electromagnetic furnace。
The methods of maintenance of the electromagnetic furnaces are as follows:
1. Power-shield burning。
Test methods: a universal watch that detects an infinity of resistance, or an eye-watching of internal blackouts or hairs, and replaces with short circuits.
2. Triple power tubes are burned, broken or short-circuited。
Testing methods: a single table detects three tripods, or none, and replaces one of its own about $10-20, which is more expensive. Power level three damage causes the power tube to burn down。
3. The operating panel has to press key failure。
The electromagnetic furnace's computer panel is usually more bad than four whole-stream diodes damaged by one。
Four, no b1, no power, no light。
Solutions: see if there are environmental factors around us, such as plugs falling, fuses breaking off or automatic switches breaking off. See if the pot is suitable, whether it is in the right place and if the diameter is less than 12 cm. There may also be a problem with the internal parts。
5. The functionality keys and indicators are normal, but sound alerts are clear。
Solutions: checking the power panels, maybe the resistance has a problem and needs to be replaced。
6. So the wire is plugged and the light is on, but the electromagnetic furnace is not hot。
Solutions: lock the wires; change the diodes at steady pressure; change the basic components。
If the above-mentioned conventional method does not solve the failure, take all the outer parts of the lf339 or other types of integrated blocks down and measure first the electrolytic capacitor capacity, with a number of occasional failures caused by insufficient capacity or failure, and if the measurements are normal, there is no need to replace them. The failure of electricity is measured in the 10k index table because the electromagnetic furnaces are hot and fragile and the quality of electrolytic capacitors is not good, and most electromagnetic furnaces have electrolytic capacitors, i. E. A few, which generally do not exceed 10。
Home appliances, after some time in use, are adsorbed with a lot of dust and dirt, turning home electricity into an inner-scrambling "hocage" of dirt, causing great harm to the health of families. Moreover, electrostatic particles, metal dust, soot, etc. In the environment can form a stain membrane on electrical components of home electricity and circuit boards, which can seriously affect the stability of the operation of the equipment and eventually lead to increased power consumption, shorter operational life, functional disorders, short circuits, burning of electronic components, and even fires。
