What are the reasons of noise from Fujitsu Inverter?
- Ppaul61Sep 12, 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. During operation, a slight squeaking sound may occur due to minute expansion and contraction of the front panel caused by temperature changes. During heating, a sizzling sound may occasionally occur, which is produced by the automatic defrosting operation.
