answerThe noise emitted by the induction cooker during operation may be caused by fan failure, transformer failure, or electromagnetic coil failure. Check if the fan is stuck or damaged, and replace it if necessary; Check if the transformer is overheated or damaged, and replace it if necessary; Use a multimeter to check the resistance and continuity of the electromagnetic coil. If there is a malfunction, replace the electromagnetic coil

answerUneven heating may be caused by uneven bottom of the cookware, uneven current distribution, or temperature sensor malfunction. Use a flat bottomed cookware to check the gap between the electromagnetic coil and the bottom of the cookware to ensure even distribution; Check if the temperature sensor is damaged or poorly wired, and replace the sensor if necessary

answerThe failure to display on the screen may be caused by screen malfunction, power failure, or control board malfunction. Check if the power supply is normal, disconnect the induction cooker from the power supply, and then reconnect it; Check whether the display screen is damaged or the wiring is loose, and replace the display screen if necessary; Check for signs of burning or damage to the control board, and replace it if necessary

answerIf there is no response when plugged in, it may be due to a broken button or a dirty or leaking button board. To address this issue, simply changing the buttons or cleaning the keypad can solve it; It may also be an internal circuit malfunction, such as blown fuses, damaged power modules, etc., which requires professional maintenance

answerThe automatic stop of heating during water boiling may be caused by overheating protection activation, dry burning protection due to water drying out, temperature sensor malfunction, and other reasons. Check whether the cooling system is normal, whether there is dry burning, and whether the temperature sensor is damaged. If there are any problems, deal with them in a timely manner

answerThe appearance of odor may be caused by foreign objects entering the induction cooker, aging and heating of components, and other reasons. The use of the induction cooker should be immediately stopped, the plug should be unplugged, and after it cools down, the interior should be checked for any foreign objects. If any are found, they should be cleaned thoroughly; If there is suspicion of component failure, it is necessary to send it to professional maintenance personnel for inspection.

answerThe decrease in power may be caused by unstable voltage, aging power tubes, electromagnetic coil failures, and other reasons. Check if the voltage of the household power supply is stable, and use a voltage regulator if necessary; If there is suspicion of a power tube or electromagnetic coil malfunction, a professional should use a multimeter to test and replace it after determining the fault

answerThe fuse burning out indicates that there is a short circuit or overload fault inside the induction cooker. Do not replace the fuse directly. First, check the internal circuit of the induction cooker, such as the rectifier bridge, capacitor, IGBT tube, etc., for any breakdown or damage, as well as whether there is a short circuit in the power circuit. After troubleshooting, replace the fuse with the same specification

answerIn general, ordinary glass cookware is not suitable for use on induction cookers because glass material cannot effectively conduct magnetism and cannot generate enough heat to heat food. But there are some microcrystalline glass cookware specifically designed for induction cookers on the market, whose bottom containspermeability magnetic materialIt can be used on an induction cooker.

answerThe service life of an induction cooker is generally around 5-10 years, and the specific service life depends on factors such as frequency of use, usage environment, and maintenance. If used properly and regularly cleaned and maintained, the service life of the induction cooker can be relatively extended; On the contrary, if used improperly or exposed to harsh environments for a long time, its service life may be shortened.
