What is the problem that Midea's air conditioner does not respond to electricity? Chongqing air-condition maintenance

The main reason why the air conditioner is not electrified is that the outdoor leakage protector is broken, the power socket is dead or the power cord is broken. The solution to the problem that the air conditioner is not electrified: Step 1, check whether the air conditioner power plug is plugged in properly; Step 2: Check whether the air conditioner remote controller has power supply; The third step is that general indoor air conditioners have emergency switches to test the quality of the air conditioner remote controller. If the emergency switch can be connected to the power supply, you should choose to replace the remote controller. The power socket is broken or the power cord is broken (measure the current on the 220V power supply of the transformer in the main control panel. If it fails, check the socket and power cord and replace it). If the fuse on the main control board blows. Take off the insurance and have a look. If it turns black or damaged, please replace it. ) main control board transformer overheating protection device burned out. (Use an ohmmeter to measure the high voltage part of the transformer. If the pointer or number is displayed, it proves that there is no problem in the high-voltage section, and the resistance value of the low-voltage section is generally zero. ) The main control board line is disconnected. The reason is as follows: 1, the air conditioning power socket is loose, try plugging it in again. 2. If there is no response, it should be a trip or the power transformer of the air conditioner is broken. Solution: 1 Check the power supply of the air conditioner, turn off the switch, turn it on again immediately, and see the indicator light on the air conditioner flashing, which proves that the user's power supply is ok. 2. Check the remote control: press the on key of the remote control, and if a triangle symbol appears instantly on the screen, it proves that the remote control is ok; However, if the battery is used for a long time, the voltage will be too low, and the transmitted signal will be weak, and the air conditioner will not receive the signal. At this time, the battery should be replaced.
