1. When the air conditioner malfunctions, it can be seen whether there is a problem with the connection head of the indoor and outdoor units of the air conditioner, as well as whether there is dust on the air conditioner condenser. Then, it can be seen whether the blowers of the indoor and outdoor units of the air conditioner are operating normally. Then check whether the intake pipe of the compressor is dewy and whether the filter is frosted or blocked. At the same time, you can also see the air conditioning fault code displayed on the air conditioning display, and judge the air conditioning fault based on the air conditioning fault code. 2. In addition to checking for air conditioning malfunctions, you can also use listening methods to check. Firstly, listen to the sound of the air conditioning outdoor unit and indoor unit fans running smoothly, and whether there are abnormal sounds caused by friction and resonance during compressor operation. 3. Touch Check. The main purpose of touching is to sense the normal temperature generated during the operation of various components of the air conditioner, and to check if the temperature is too high during operation due to air conditioning faults. 4. After seeing, listening, and touching, one can also use the method of smelling. Smelling is mainly to smell whether the inner and outer coils of the air conditioning compressor have a burnt odor caused by the temperature rise of the compressor, and to smell whether the substrate, relay, and power module have a burnt odor. The method of smelling is also to confirm whether there is a burnt smell emitted by the air conditioner due to excessive temperature during use
