Refrigerant leakage: abnormal system pressure or oil stains on the pipeline indicate leakage, and leak detection and refrigerant replenishment are required.
Compressor failure: check whether the starter and coil are damaged, or replace the aging compressor.
Dust accumulation on the condenser: poor heat dissipation leads to reduced efficiency, clean the surface dust regularly or adjust the ventilation environment.
Aging of the door seal: poor sealing leads to air leakage, and the damaged door seal is replaced.
Thermostat failure: calibrate the sensor or replace the faulty thermostat.
Ambient temperature is too high: avoid direct sunlight or high temperature areas, and ensure that there is sufficient heat dissipation space around.
If self-checking is ineffective, it is recommended to contact professional maintenance personnel to detect system pressure and circuit problems.
