Why is there noise coming from my Fujitsu Halcyon ASU9RLQ?
- AAnthony HaynesSep 13, 2025
During operation, and immediately after stopping your Fujitsu Air Conditioner, the sound of water flowing in the air conditioner’s piping may be heard. Also, during operation, a slight squeaking sound may be heard due to minute expansion and contraction of the front cover caused by temperature changes. During heating, a sizzling sound may occasionally be heard, which is produced by the Automatic Defrosting operation.
