Indoor code situation table:

LED status indication content

Running light 1HZ flashes at first power on and normal standby

Running light flashes at 5HZ immediately after power-on The room temperature sensor or evaporator sensor is open circuit Or short circuit

After power on, the running light flashes at 5HZ for one minute, and the speed of the indoor fan is out of control

The running light and timing light flash at 5HZ The thermal fuse is open

Running light, timing light, defrost light (or only air supply light) flashes at 5HZ

1. The compressor connection is not well connected, the compressor overcurrent protector is open or the electric control is broken

2. The power supply voltage is too low

. Electric control parts are faulty or leaking fluorine

Use the remote control to judge: (This judgment method is applicable to the original gray remote control)

After pressing the rightmost button of the remote control battery for a second, the remote control displays 00, use The temperature

adjustment button can change the displayed number and transmit it to the host through the remote control (as long as the electric control is normal, it can be received and displayed through thelight is displayed), for items with no problem, only the timing light flashes, otherwise both the timing light and the running light flash.

Level diagnostic function

Mainboard

0C The temperature sensor head at room temperature continues to run abnormally
