The IGBT model used in the high pressure plate of M3-L234E inverter microwave oven is IRG4PC50U. The circuit board MCU near the 8-pin chip, may be 24c02 or other memory with larger storage space. Used to save the Settings before the power failure. Start up again, read its internal data first, and work according to the saved data. LNK364PN.According to the query of the relevant information of the United States microwave oven, the integrated block of the United States microwave oven frequency conversion board is LNK364PN model. The oven capacity of the variable frequency microwave oven is increased by more than 20% and can be put into a larger plate. z is the PWM control chip. To-92 pin package. It is interchangeable with AP3700z. is estimated to be AP3700, it is not a transistor, is a three-terminal switching power PWM control chip. VIPER22A, AP8022, PN8123, P8024R can be. Power block ap8023 is the power chip of Midea induction cooker. The first step: Switch on the power of the rice cooker after proper preparation. Step 2: Select according to your own needs Select the function buttons you need to use. After the AP8023 is damaged, the replacement models are: AP802P8024R, VIPER22A, PN8123. If the working power supply is 5V, the high level is close to 5VLow level approaching 0V. If the working power supply is 3V, the high level is close to 3V and the low level is close to 0V. If the working power supply is 5V, the high level is close to 5V and the low level is close to 0V. Power block ap8023 is the power chip of Midea induction cooker. Induction cooker, also known as induction cooker, consists of a high-frequency induction heating coil (i.e. excitation coil), a high-frequency power conversion device, a controller and a ferromagnetic material pot bottom cooker. General, ap8023 with VIPER22A, AP8022, PN8123, P8024R can be Chip burn For a long time, induction cooker chip may be burned due to aging electronic components, overload use or circuit short circuit and other reasons. The burned chip needs to be replaced, otherwise the induction cooker cannot work normally. Check the power supply. First, make sure that the plug and power cord are not damaged and that the plug can contact normally. If the induction cooker still does not work properly, it may be a power failure. You are advised to replace the power supply. Check the chip connection. Sometimes, the chip connection may be poor, causing the induction cooker to not work properly. In short, the causes of induction cooker power chip failure may include over current, over voltageFactors such as excessive temperature and instantaneous voltage. For different reasons, different measures need to be taken to repair, such as replacing capacitors and inductors, optimizing the induction furnace ventilation system, insulating the circuit, etc. The performance of the broken electromagnetic oven cpu is as follows: the CPU power foot is short circuit, the indicator light is not bright, and the key has no reaction. The CPU works abnormally, the indicators are all on, and the buttons do not respond. The CPU is abnormal and the power tube is burned. Induction cooker is also known as induction cooker, the first household induction cooker was born in Germany in 1957. 1, LNK364PN, SM7028B. LNK364PN is a low-power high-efficiency off-line switching IC, often used as a power management chip for induction stoves, with high circuit efficiency. The chip can be directly replaced with LNK564PN, or replaced with TNY266, and the first pin is suspended with 0.1UF and 63V capacitors to the ground. 2, BCD decimal decoder/driver. The model of 16-pin chip of Midea induction cooker control panel is BCD decimal decoder/driver. BCD decimal decoder /The driver adopts a double-row 16-pin main package, and its chip models are a total of 3 kinds, models are 74HC14CT7414CT74LS1451. 3, About the above problems are listed as follows: Single-chip chip GC87C510A, HMS87C1202A, TMP86C807MN, MC908QY4CP, S3F9454XZZ-DKBHT46R2TMP87C809JD, HT162, etc. This is the induction cooker microcomputer chip. 4, power block ap8023 is Midea electricityPower chip for magnetic furnace. The first step: Switch on the power of the rice cooker after proper preparation. Step 2: Select according to your own needs Select the function buttons you need to use. Step 3: Press the "Appointment" button, calculate the time, and set the time. 5, S3F series of Samsung microcontroller, widely used in the United States, Galanz, Pentium and other brands of induction cooker, pressure cooker, electric frying pan such small household appliances. When data needs to be read or written during maintenance or chip replacement, the RT809F can be used to complete the read and write. 6, PN8124f. According to the investigationAccording to the introduction of induction cooker, the power chip model of the item is PN8124f, which is a commonly used IC chip for induction cooker power drive, and the tower is packaged with DIP7. Induction cooker is an electric cooking appliance made of the principle of electromagnetic induction heating. Power block ap8023 can be replaced by what block?
