What are the faults in the electric ceramic stove? Electric ceramic stove fault repair method

No electrical appliance can guarantee no failure when it is used. The electric ceramic stove is no exception. The first thing to do when the electric ceramic stove fails is to check the cause of the malfunction, so that the right medicine can be solved. What are the faults of the electric ceramic stove ? The following decoration home decoration network Xiaobian will bring you the electric ceramic stove fault repair method, I hope to provide help for everyone.

What are the faults in the electric ceramic stove?

Electric ceramic furnace failure 1. Poor contact between thermocouple and main board:

Electric ceramic stove repair method: If the electric ceramic stove is energized, the digital tube displays E2, and the buzzer alarms, it may be that the thermocouple is in poor contact with the main board (check the "MAIN" 2P socket on the main board for soldering, false soldering, soldering and soldering. The point is off, the socket and the thermocouple connection line are loose) or the thermocouple is damaged (the temperature of the thermocouple output should be turned on with the multimeter resistance gear position; the thermocouple temperature point solder joint is off). At this time, you can try to repair the "MAIN" 2P socket on the motherboard. Plug in the thermocouple socket or replace the thermocouple.

Electric ceramic furnace failure 2, circuit failure:

Electric ceramic stove repair method: If the electric circuit oven motherboard operational amplifier part of the circuit is faulty, can be in the resistor ( R7, R17, R16, R19, R18, R22, R2, R10), capacitor (C4, C6, C8, C9, EC1) Use a multimeter to measure the op amp output voltage: Turn the multimeter to the DC voltage range. Negative meter pen connected to the motherboard "negative" (IC1L7805 middle foot or connected line) positive pen connected to the main board resistor R22 (near the end of the socket) voltage at room temperature is about 0.003V, if the voltage ≥ 3.0V indicates that the integrated operation amplification part is faulty. Check the integrated op amp part for the wrong part (take a good motherboard for comparison), soldering, false soldering, soldering, solder joint dropout and component damage. In this case, you can try to repair the motherboard op amp part of the circuit, or replace the same parameter components.

Electric ceramic furnace failure 3, poor connection between the light board and the motherboard:

Electric ceramic stove repair method: If the electric ceramic lamp board and the main board are not well connected, check the 9P socket on the main board and the 9P cable JP1 on the lamp board for solder joint welding, false soldering, soldering and falling off, main board 9P If the socket and the lamp board are loose, use the multimeter resistance gear to measure the board line on the lamp board. The same line should be turned on. It can repair the 9P socket and cable plug on the main board and the lamp board. Or plug in the solid board and motherboard connection cable and replace one cable.

The above is what is the fault of the electric ceramic stove brought by Xiaobian?
