Jiuyang Company has continued to expand in the field of healthy kitchen appliances, and new products have emerged endlessly. The main products include soymilk machines, electric pressure cookers, induction cookers, electric kettles, cooking machines, juicers, pot pots, new kitchen appliances, etc.Multiple models.In my countrys current induction cooker sales market, Jiuyangs induction cooker has become the only control technology for controlling rotation, leading the development of my countrys induction cooker technology.
What to do if Jiuyangs electromagnetic cooker failure
Jiuyang induction cooker failure code and solution 1. Fail code display E0
Internal circuit failure alarm: When the internal circuit fails, it cannot work properly, the digital display number displays E0, and the bee tweezer shakes at a frequency of 1 second.The alarm state cannot be exited automatically. After manual shutdown, it is necessary to turn on the alarm state (if E0 is still displayed, please go to the maintenance outlet for check).
E0: Internal circuit failure
Check the inspection of the internal row and the line disk lead.Check whether the components on the board are intact (such as the burning black).Check the welding point (virtual welding, leakage welding, etc.).Touch whether the CPU and LM339 are too high (after power off), first remove the pins of the line disk to check the check+5V,+15V is normal, and whether the voltage of the LM339 pin is normal.Measure whether the R21-R24 high-voltage resistance is normal (disassembled measurement) to check whether the Q12-Q15 triode is penetrated or opened.
Jiuyang induction cooker failure code and solution 2. Fail code display E1
No matter what working state of the induction cooker is in, if the non -pot -free, pot ingredients are not suitable, and the heating object is small objects, the output is closed immediately, and the pots are repeatedly detected.The frequency sound of 1 second.If the pot has been continuously abnormal within 1 minute, the alarm will be automatically shut down after 1 minute; if the situation of the pot will return to normal within 1 minute, automatically withdraw from the fault alarm state and restore the original state of work (if E1 is still displayed, please go to the maintenance outlets.examine).
E1: The shape of the pot is not suitable for or not inspected the pot, iron material. Focus on checking whether the voltage of 8, 9, 14 of LM339 is deteriorated.
Jiuyang induction cooker failure code and solution 3. Display fault code display E2
IGBT overheating (over -temperature in the furnace) alarm: When IGBT is overheated (exceeding 100 ° C), turn off the output, the digital tube displays E2, and the bee tweee is shouted at a frequency of 1 second.The alarm state cannot be exited automatically, and it is necessary to turn off manually to exit the alarm state.When the temperature returns to normal, the manual boot is normal (if E2 is still displayed, please go to the maintenance outlet for check).
E2: The ultra -temperature or NTC failure (IGBT) is turned on to display E2; whether the thermal resistance is deteriorated (IGBT) CPU19 has no output; the E2 is displayed after heating;Whether the fan rotates, whether the speed is low, etc.
Jiuyang induction cooker failure code and solution 4. Display fault code display E3/E4
Overvoltage and under pressure failure alarm: When the power grid voltage is abnormal, the machine stops heating immediately, and the Digital display area displays the fault code (the power grid voltage is higher than 270V. The overvoltage fault code E3 is displayed.E4, at the same time, the bee tweezers are tweeting at a frequency of 1 second.When the voltage is restored to normal, the state of the fault is automatically exited and the original working state is restored.In 2007, 21T, 23T, 19TK main control board and 2008 21TD1 voltage design low voltage 100, recovery value 110V, high voltage 285V, recovery 280V.
When the voltage is normal, the induction cooker appears E3, E4
When the user appears E3/E4, the power grid voltage should be tested normally; the scope of the satisfaction range of our electromagnetic cooker power grid is 265V ~ 275V, and the lower limit 150V ~ 170V (the voltage range of the electromagnetic cooker after 07 will be wider);The E3/E4 appears that the high and low voltage protection circuit occurs. Most of the high -voltage resistance (voltage voltage) variable values ??(if the E3/E4 is still displayed, please go to the maintenance outlet for check).
E3: Excessive voltage of the grid
E4: Power grid voltage is too low
Consider external voltage.(180V-250V) Check whether the voltage of the CPU15 pin is normally measured by D91, D92, R91, etc.Code and solution 5. Failure code display E5/E6
Temperature sensor opening, short -circuit alarm: The ceramic plate temperature sensor is displayed when the road is opened, and the E6 is displayed in short circuit. The IGBT temperature sensor is displayed when the road and short circuit are displayed, and the output is closed immediately.At the same time, the bee tweet is shouted at a frequency of 1 second.The alarm state cannot be exited automatically, and it needs to be manually shut down to exit the alarm status (if the E5/E6 is still displayed, please go to the maintenance outlet for inspection).
E5: Ceramic plate sensor opens, E6: ceramic plate sensor is short -circuit or dry burning protection, check whether thermal resistance is open, short -circuit, R70, etc.A 470k resistor can be connected on the thermistor (the temperature is too low in some places), and the thermal silicon grease on the sensor is dry.The current detection circuit (transformer, potentiometer, CUR signal), drive circuit (Q12-Q15 triode, PWM signal), synchronous oscillating circuit (8, 9, 10, 11, voltage, etc.).
Jiuyang induction cooker failure code and solution 6. Fail code display E7
The temperature of the wire plate is too high E7 protection, and the bee tweee is shouted at a frequency of 1 second.The alarm state cannot be exited automatically, and it needs to be manually shut down to exit the alarm status (if E7 is still displayed, please go to the maintenance outlet for check).
E7：电磁线盘超温开机显示正常、不加热，电流检测回路(互感器、电位器、CUR信号)，驱动电路(Q12-Q15三极管、PWM信号)，同步振荡电路(LM339的8、9、10, 11, voltage, voltage, etc.), the CPU does not work without working.
Check whether the insurance pipe is opened and the IGBT three pole is short -circuited.Check whether Q12-Q15 is normal.Replace the same model of IGBT and insurance tubes.IGBT and rectifier bridge evenly apply heat -conducting silicon grease, and the power -based test machine cannot be wiring !!
Jiuyang induction cooker failure code and solution 7. Fail code display E8
Pressing the motion protection function: In any state, when the machine recognizes that a key is closed for more than 1 minute in a row, the digital tube displays the E8, the alarm can not be automatically exited, and the alarm is required manually.When adjusting the time, you may hold the [hour] or [minutes] key, but you still need to call the police for more than 1 minute (if the E8 is still displayed, please go to the maintenance outlet for check).
E0: Internal circuit faults; E1: No pot or pot (material, size, shape, location) inappropriate; E2: The internal heat dissipation of the machine or the temperature sensor in the machine;Too low; E5: Ceramic plate temperature sensor is broken; E6: The pots of the pot, the temperature of the pot, the temperature of the pot is too high, and the ceramic plate temperature sensor is short circuit.
