Summer is the peak season for using air conditioners. Many consumers feel that the air conditioning and cooling in the home is always weak, and the sound of the air conditioner is also getting bigger. Is the air conditioner in the home broken? Is it necessary to repair? How can I accurately check it? ?
Symptom 1: The air conditioner does not work
Self-test method: Is there a power failure? Is the power fuse disconnected? Is the power on/off in the “off†position? Is the power plug not plugged in?
Symptom 2: loud noise
Self-test method: Is the installation tilted? Is it firm? Is the wall resonance too large? Is the grille closed?
Symptom 3: The cooling or heating effect is not good
Self-test method: Is the setting method correct? Is the matching reasonable? Is there any dust blockage on the filter network? Is the air inlet and air supply port of the indoor unit or outdoor unit blocked? Is the set temperature too high (low)? Is it using electricity? At the peak, the voltage is too low or too fluctuating. Is the heating poor, is the outdoor temperature below -7 degrees Celsius? Is the cooling poor, is the outdoor unit exposed to the sun or the outdoor temperature exceeds 45 degrees Celsius?
