Record of the Sharp Air Conditioner Maintenance Process; Outdoor Unit Occasionally Makes a Lot of Noise
Fault Phenomenon: The outdoor unit occasionally makes a lot of noise, especially when the compressor stops and starts.
Maintenance Process: This is a newly installed machine for just a few days. The user reported that the outdoor unit was making noise. Upon opening the top cover of the outdoor unit, it was found that the excessive cooling pipe of the outdoor unit was too close to the casing, causing collision sounds. Adjusting the pipe by hand resolved the issue. After covering the top cover of the outdoor unit again, the user no longer experienced any noise. More than 10 machines have been found to have this issue where the pipes collide with the casing (for newly installed machines, users generally do not agree to repairs, so installation personnel must ensure everything is correct from the start and should also possess some maintenance knowledge).
Maintenance Measures: Adjust the pipe of the outdoor unit. For newly installed machines, both cooling and heating functions must be tested by switching once to avoid other issues.
