  If your Fujitsu Air Conditioner isn't cooling or heating well, consider these points: * Ensure the room temperature settings (thermostat) are correctly adjusted. * Check if the air filter is dirty and clean it if necessary. * Make sure the air conditioner's inlet or outlet port isn't blocked. * Close any open windows or doors. * If cooling, close curtains to block bright sunlight. * Reduce heat-generating appliances or the number of people in the room. * Increase the fan speed if it's set too low.

Why does my Fujitsu AIRSTAGE ASYA18GACH airflow is weak or stops?
- M
  Mary BowenAug 18, 2025
  Weak or stopped airflow in your Fujitsu Air Conditioner can occur due to several reasons: * When heating starts, the indoor unit's fan may temporarily stop to warm up internal parts. * During heating, if the room temperature exceeds the thermostat setting, the outdoor unit and indoor fan will stop. Lower the thermostat if you want to warm the room further. * Airflow may stop for about 10 minutes during oil recovery operation. * The unit will temporarily stop for 4-15 minutes during heating as the automatic defrosting mode operates. * The fan may operate at low speed during dry operation or when monitoring the room's temperature. * In monitor AUTO operation, the fan will operate at low speed.

  Your Fujitsu Air Conditioner might not start immediately because: * If stopped and restarted quickly, the compressor won't operate for about 3 minutes to prevent fuse issues. * After turning the electrical breaker off and on, the protection circuit operates for about 3 minutes, preventing immediate operation.

Why is the OPERATION indicator lamp flashing on my Fujitsu AIRSTAGE ASYA18GACH?

  Roberto FosterAug 27, 2025
  The OPERATION indicator lamp (green) on your Fujitsu Air Conditioner may be flashing because: * An oil recovery operation is being performed. * An automatic defrosting operation is being performed. Also, the OPERATION indicator lamp (green) and TIMER indicator lamp (orange) may be flashing alternately because it has recovered from a power outage. They may be flashing simultaneously because it is operating in trial operation mode. The OPERATION indicator lamp (green) may be lit and the TIMER indicator lamp (orange) may be flashing because the unit is in standby state.

  Jordan PorterSep 2, 2025
  Your Fujitsu Air Conditioner might produce sounds for several reasons: * You may hear sounds of water flowing from the indoor unit, and the operation sound becomes loud. These are the sounds of the flowing of refrigerant. * A slight squeaking sound may occur due to minute expansion and contraction of the panel because of temperature changes. * During heating, a sizzling sound might be heard occasionally, which is produced by the automatic defrosting operation.
