What are the common faults and repair methods of commercial induction cookers?

With the development of social progress and the improvement of people's living consumption, people are generally pursuing the process of "enjoyment", just like more and more people choose to eat out now, and every time it's meal time, all major restaurants are crowded with people. The commercial induction cooker is one of the kitchen equipment to solve the problem of a large number of people eating; the commercial induction cooker will encounter some faults more or less during use. Today, SHINELONG editor will share with you: What are the common faults and maintenance methods of commercial induction cookers? What are the common faults of commercial induction cookers? 1. The commercial induction cooker does not heat: When in use, if the indicator light is on and the commercial induction cooker alarms and does not heat or heats intermittently, for commercial induction cookers that have been used for a long time, such a situation will generally occur because its micro switch has a fault. Maintenance method: After the micro switch of the commercial induction cooker is damaged, it will cause the commercial induction cooker CPU to make an incorrect judgment when working, which will eventually cause the indicator light to be on and the commercial induction cooker alarm does not heat. The main thing when repairing the commercial induction cooker is to replace its micro switch. 2. Repair method for the inability to adjust the power of a commercial induction cooker during use: In the repair method of a commercial induction cooker, such a situation may be caused by a short circuit in the heating/temperature-controlled resistor of the commercial induction cooker, which causes the power adjustment button on the operation panel of the commercial induction cooker to be unusable. At this time, when repairing the commercial induction cooker, it is necessary to replace the damaged components. Damage to the main control IC will also cause the inability to adjust the power of the commercial induction cooker during use. Generally, commercial induction cookers with a long service life are most likely to have such problems. If the commercial induction cooker is in a high temperature environment for a long time, the probability of IC damage will increase. When repairing the commercial induction cooker, we need to replace the IC of the induction cooker. 3. The commercial induction cooker does not turn on (the indicator light does not light up when the power button is pressed) (1) The button is bad, check and replace the button board; (2) The power cord is loose, reconnect the power cord; (3) The power cord is not powered, reconnect the power cord or replace the power cord; (4) The fuse is blown, replace the fuse; (5) The transformer is broken, there is no 18V output, check and replace the transformer; (6) The baseboard assembly is broken, replace the baseboard assembly; 4. The commercial induction cooker has no response: The commercial induction cooker has no response and has not exploded. When the commercial induction cooker is disassembled, no fuse is found to be burned. It can be preliminarily determined that the power chip of the commercial induction cooker is damaged. Repair method: The 18V voltage generated by the power chip will become +5V voltage after passing through 7805 for the CPU to work. At this time, if the corresponding voltage cannot be provided, the commercial induction cooker CPU will not work normally. At this time, we mainly test its chip when repairing the commercial induction cooker. 5. Unstable voltage: The commercial induction cooker will trip and stop working due to unstable voltage during use. Maintenance method: Correctly select the transformer ratio and voltage tap, reasonably reduce line impedance, improve power factor, and automatically switch the capacity of reactive compensation equipment according to voltage and load changes; according to the power system flow distribution, timely adjust the operation mode, adopt load-based voltage regulation, such as using load-based voltage regulation transformers, etc. The above are common faults and maintenance methods of commercial induction cookers. If the above faults occur, do not repair them yourself, and contact the manufacturer in time to ask the master to come to your door for repair; of course, there are many other faults of commercial induction cookers, and SHINELONG editor will not introduce them here. Later, SHINELONG editor will release some precautions for the use of commercial induction cookers, and I hope everyone will pay attention.
