Why is water produced from the outdoor unit of my Fujitsu AOU12R1?
During heating operation, water may be produced from the outdoor unit of your Fujitsu Air Conditioner because of the automatic defrosting process.
Why doesn't the outdoor unit of my Fujitsu AOU12R1 Air Conditioner stop after heating?
The outdoor unit of your Fujitsu Air Conditioner may continue to run even after heating stops to perform automatic defrosting if frost is detected on the unit.
Why is my Fujitsu AOU12R1 airflow weak or stops?
There are several reasons why the airflow from your Fujitsu Air Conditioner might be weak or stop: * When heating starts, the fan speed is temporarily very low to allow internal parts to warm up. * During heating, the unit may temporarily stop for 7 to 15 minutes for automatic defrosting. * The fan might operate at a very low speed during dry operation or when the unit is monitoring the room's temperature. * In SUPER QUIET mode, the fan operates at a very low speed. * In monitor AUTO operation, the fan also operates at a very low speed.
Why does my Fujitsu AOU12R1 Air Conditioner smell?
The smell emitted from your Fujitsu Air Conditioner's indoor unit may be due to room odors, such as those from furniture or tobacco, that have been drawn into the unit.
Why does my Fujitsu AOU12R1 make noise?
Your Fujitsu Air Conditioner might make noise due to these reasons: * During and shortly after operation, you might hear water flowing through the unit's pipes. * For about 2 to 3 minutes after starting, you may notice noise from coolant flowing. * During heating, a sizzling sound may occur occasionally due to automatic defrosting.
Why doesn't my Fujitsu AOU12R1 Air Conditioner operate immediately?
Your Fujitsu Air Conditioner may not start immediately under these circumstances: * If the unit is stopped and restarted quickly, the compressor will be disabled for about 3 minutes to prevent fuse issues. * If power is disconnected and then reconnected, a protection circuit will activate for about 3 minutes, preventing operation.
