Induction cookers have gradually become an indispensable part of our lives, and they are especially indispensable when having hot pot. So, during the use of induction cookers, what problems are we most afraid of encountering? The editor believes that an induction cooker is indispensable for heating. Now, let's take a look together at the reasons why induction cookers do not heat up and the solutions.

The reason why the induction cooker doesn't heat up

Internal factor condition protection

①IGBT overcurrent protection: Overcurrent protection forces a reduction in output power or directly suspends operation. After a delay period, it restarts and enters the working state. When such protective actions occur, there will be a phenomenon of "regular intermittent heating".

② Temperature sensor open circuit and short circuit protection: This type of protection will force the induction cooker to shut down when it is in operation and keep it in the off state until the fault is eliminated. No keys will function and the induction cooker fault code will be displayed.

③IGBT overvoltage protection: When the collector voltage of the IGBT rises for some reason and reaches the protection trigger condition, the overvoltage protection operates, forcing the induction cooker to reduce the output power, and the collector voltage of the IGBT drops immediately. Sometimes, when this type of protection circuit operates, phenomena such as intermittent heating and reduced output power may occur.

2. Protection under external natural factor conditions:

Surge protection: A surge is a relatively harmful sharp pulse generated when the voltage in the power grid rises or falls instantaneously. Generally, excessive surges are discharged by varistors, while only a few smaller surges will trigger the surge protection circuit to act. The nature of protection is a short-term pause. If the power grid is old and there is poor contact, there may be occasional pauses.

② Grid voltage protection: Protection occurs when the voltage is high or lower than the working voltage range of the induction cooker. The protection nature is forced standby and displays fault codes.

③ Internal overheating protection of induction cookers: The trigger temperature for protection is mostly between 90 and 95 degrees, and the release temperature is between 60 and 70 degrees. The protection nature is a temporary shutdown and a fault code is displayed. When the temperature is detected to reach 110 degrees, the protection circuit will forcibly shut down.

④ Cookware over-temperature protection: This type of over-temperature protection is also known as "anti-dry burning protection". The trigger temperature is 280 to 300 degrees. That is to say, once it reaches 280 degrees, it will automatically force the machine to shut down. The release temperature is 70 to 80 degrees. In this case, as long as it reaches 70 degrees, it can be restarted for use.

Solution for an induction cooker not heating

When the plug is plugged into the power source and no "d" sound is heard, we have to start from the source first. First, cut off the power supply of the induction cooker, and then use a current pen to test whether the socket interface of the induction cooker is damaged. If the socket is intact, we will check the power cord of the induction cooker to see if it is a problem with the power cord. If there are continuous short beeping sounds and the machine stops shortly after, then check whether the cookware in use is suitable. Cooking utensils should be placed flat in the center of the platform. The diameter at the bottom is generally no less than 12cm, etc.

If the device suddenly shuts down during use and makes a beeping sound, it is necessary to check whether the surrounding environment is too high and whether the suction and exhaust holes of the induction cooker are blocked by foreign objects, causing the internal temperature to rise. Also, check if the wrong function keys have been pressed, if the water in the cookware has evaporated, and if the POTS and pans are uneven.

When there is a problem with the induction cooker, everyone can first check the cause of the problem by themselves, which is also convenient for future maintenance. Also, the editor still suggests that if there is a problem with the induction cooker, it is better to find a professional to handle it. Blindly self-repairing and damaging the internal parts will be counterproductive. The above is what the editor has introduced to you today about the reasons why induction cookers do not heat up and the solutions. I hope it will be helpful to everyone.
