What should I do if the commercial induction cooker does not heat up and is broken? The main function of the commercial induction cooker is heating, but in many cases, when the induction cooker cannot heat up, it is not necessarily caused by an abnormality or failure of the induction cooker. The following is an analysis of the reasons why the commercial induction cooker does not heat up by the editor of SHINELONG. External natural factors: 1. Grid voltage: When the voltage is high or lower than the working voltage range of the induction cooker, the nature is forced standby and the fault code is displayed. 2. Overheating inside the commercial induction cooker: The trigger temperature is mostly between 90 and 95 degrees, and the release temperature is between 60 and 70 degrees. The nature is a suspended shutdown and the fault code is displayed. If the temperature reaches 110 degrees, the power is forced to shut down. 3. Surge: It is a relatively harmful spike pulse generated when the voltage in the power grid rises or falls instantly. Excessive surges are generally discharged by the varistor, and only some smaller surges will trigger surge electric action. The nature is a short-term pause. If the power grid is old and there is poor contact, there may be an irregular pause. 4. Overheating of the pot: also known as "anti-dry burning", the trigger temperature is 280 to 300 degrees, the release temperature is 70 to 80 degrees, and the nature is forced shutdown. Internal factors and conditions of commercial induction cookers: 1. Open circuit and short circuit of temperature sensor: This type will force the induction cooker to shut down during operation, and the commercial induction cooker will no longer be able to eliminate the fault. 2. IGBT tube overvoltage: When the IGBT collector voltage increases for some reason and reaches the trigger condition, the overvoltage action occurs, the induction cooker reduces the output power, and the IGBT collector voltage decreases immediately. This type of electrical action will cause "intermittent heating" and "reduced output power" and other phenomena. 3. IGBT overcurrent: Overcurrent forces the output power to be reduced or the work is directly suspended, and it will start again after a delay to enter the working state. This type of action will cause "regular intermittent heating" phenomenon. From the above content, we can understand that the commercial induction cooker does not heat up, in fact, there are external natural factors and its own internal factors that cause it to not heat up, and it is easy to repair and solve the problem, and the cost of repair is not high. The editor of SHINELONG believes that if electrical appliances such as home appliances break down, it is best to ask the manufacturer's maintenance technician to check whether the appliance is worth repairing before considering replacing it with a new one.
