Why is my Fujitsu AOY7USAC cooling (or heating) poorly?
- K
  Kimberly BrewerAug 4, 2025
  Poor cooling or heating performance of your Fujitsu Air Conditioner can be caused by several factors: * A dirty air filter. * Blocked air intake grille or outlet port. * Incorrect room temperature settings. * An open window or door. * Bright sunlight entering the room during cooling operation (close the curtains). * Too many heat-generating devices or people in the room during cooling operation. * The unit being set to SUPER QUIET operation.

Why does Fujitsu Air Conditioner airflow become weak or stop?
- K
  kjonesAug 13, 2025
  Weak or stopped airflow in your Fujitsu Air Conditioner can occur due to: * Low fan speed during the start of Heating operation, allowing internal parts to warm up. * The outdoor unit stopping and the indoor unit operating at very low fan speed if the room temperature rises above the thermostat setting during Heating operation. * Temporary stops (7-15 minutes) during Heating operation for Automatic Defrosting. * Very low fan speed during Dry operation or when the unit is monitoring the room’s temperature. * SUPER QUIET operation mode. * Monitor AUTO operation.

Why Fujitsu AOY7USAC Air Conditioner doesn’t operate immediately?
- J
  janicecookAug 17, 2025
  Your Fujitsu Air Conditioner might not operate immediately because: * If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes to prevent fuse blowouts. * When the Power Supply Plug is disconnected and then re-connected, the protection circuit will operate for about 3 minutes, preventing unit operation.

Why is there noise coming from my Fujitsu AOY7USAC?
- T
  Theresa StewartAug 22, 2025
  You may hear noise from your Fujitsu Air Conditioner due to: * Water flowing in the air conditioner’s piping during and immediately after operation. * Coolant flowing, particularly noticeable for about 2 to 3 minutes after starting operation. * A sizzling sound during Heating operation, which is produced by the Automatic Defrosting operation.

Why does Fujitsu AOY7USAC emit mist or steam?
- R
  Roger BrownAug 27, 2025
  Mist or steam emitted from your Fujitsu Air Conditioner can be caused by: * Sudden cooling of room air during Cooling or Dry operation, resulting in condensation and misting from the indoor unit. * The outdoor unit’s fan stopping and steam rising from the unit during Heating operation due to Automatic Defrosting operation.
