Haier air conditioning refrigeration shows sunshine.

1, the sun adjusts the heating mode, and it is usually used for heating when the weather is cold in winter, but if the air conditioner is less than 20 degrees in winter, the air conditioner will not be higher than 20 degrees when it is turned on at 30 degrees, and the heating power of the air conditioner is constant. 2. It may be because in the cooling mode, the remote control was accidentally pressed by mistake, and the heating mode was turned on. It may be because the four-way valve of the air conditioner is broken. 4. It may be because the air conditioning motherboard is faulty. Suggested treatment: set the operation method of refrigeration operation: press and hold the "mode" key on the remote control, release the "snowflake" character on the display screen, and select the appropriate control temperature when the temperature button rises or falls. Set the operation method of heating operation: press and hold the "mode" key on the remote control, release the "sun" character on the display screen, and select the appropriate control temperature when the modulation temperature button rises or falls. After the power supply is connected, the compressor will start to work. At this time, you can use the remote control for cooling or heating mode to see if the air conditioner responds. If it is effective, it can be reset to solve this fault. If the air conditioner doesn't respond, cut off the four-way valve, and then see if the air conditioner emits hot air. If the air conditioner emits hot air, it means that the four-way valve of the air conditioner is damaged, and it is necessary to contact a professional air conditioner maintenance master for maintenance and replacement, which can solve this fault of the air conditioner. If the air conditioner can't get hot air, it means that the air conditioner motherboard may be faulty. In this case, you need to contact the after-sales personnel to repair and replace them in time. Of course, there is a phenomenon that the air conditioner changes from refrigeration to heat, and it is also possible that the remote controller of the air conditioner has a failure to receive it. Replacing a remote control can completely solve this problem.
