Why is my Fujitsu Air Conditioner cooling so poorly?
- K
  Kelly PerezAug 17, 2025
  To address poor cooling performance in your Fujitsu Air Conditioner, consider the following: * Check if the air filter is dirty. * Ensure that the air conditioner’s intake grille or outlet port isn't blocked. * Verify that the room temperature settings (thermostat) are correctly adjusted. * Make sure no windows or doors are open. * If it's cooling operation, close curtains to block bright sunlight and reduce heat sources like heating apparatus or computers. Also, check that the unit is not set to SUPER QUIET operation.

How to fix Fujitsu AOU15RLQ that doesn’t operate immediately?
- S
  Shannon BlakeAug 20, 2025
  If your Fujitsu Air Conditioner doesn't operate immediately after being turned on, it could be due to a built-in protection mechanism. The compressor might not start for about 3 minutes to prevent fuse blowouts. Similarly, if the power supply plug was recently disconnected and reconnected, the protection circuit might prevent operation for about 3 minutes.

Why does the airflow from my Fujitsu AOU15RLQ become weak or stop?
- R
  Richard BernardAug 22, 2025
  Weak airflow or complete stops in your Fujitsu Air Conditioner can occur for several reasons: * When heating starts, fan speed is temporarily low to warm internal parts. * If the room gets too warm during heating, the outdoor unit stops, and the indoor fan runs very slowly. * The unit temporarily stops during heating for 7-15 minutes for automatic defrosting. * The fan runs at very low speed during dry operation or when monitoring room temperature. * The fan runs at very low speed during SUPER QUIET operation. * The fan runs at very low speed during monitor AUTO operation.
