Why doesn't my Fujitsu AST13PSA–W Air Conditioner operate immediately after turning it on?

  Your Fujitsu Air Conditioner might not start immediately due to a built-in protection mechanism. If the unit was recently stopped and restarted, the compressor might be delayed for about 3 minutes to prevent fuse issues. Also, if the Power Supply Plug was recently disconnected and reconnected, the protection circuit could prevent operation for about 3 minutes.

Why is the airflow weak or stopping in my Fujitsu Air Conditioner?
- N
  Nicole FitzgeraldSep 1, 2025
  Weak or absent airflow in your Fujitsu Air Conditioner can be due to several reasons. When heating starts, the fan speed is temporarily low to allow internal parts to warm up. During heating, the unit may temporarily stop for 7-15 minutes for Automatic Defrosting. The fan may operate at very low speed during Dry operation, when monitoring room temperature, during SUPER QUIET operation, or in monitor AUTO operation.
