causing excessive dust accumulation that affects air circulation

Methods for Diagnosing Non-Fault Issues with Sharp Air Conditioners

1. In summer, when the ambient temperature exceeds 36℃, if there are too many people in the room, exceeding the thermal load that the air conditioner can handle, it may lead to excessively high indoor temperatures and poor cooling effects. Simply reducing the number of people in the air-conditioned room will restore normal operation.

2. If the power voltage is too low, it may cause difficulty in starting the air conditioner or frequent blowing of fuses. Adjusting the power voltage higher or installing a home voltage stabilizer to ensure the voltage reaches the rated level will restore normal operation.

3. A loud noise during fan operation at high speed is a normal phenomenon.

4. Failure to clean the air filter regularly can result in excessive dust accumulation, affecting airflow and causing poor cooling performance. Timely cleaning of the air filter will restore normal cooling efficiency.

5. Improper adjustment of the temperature controller, set either too high or too low, may cause abnormal operation of the air conditioner. For example, setting the temperature too high in summer may prevent the air conditioner from running. During maintenance, simply adjust the thermostat towards a lower temperature setting to restore normal operation.
