  Several factors can impact the cooling or heating performance of your Fujitsu Air Conditioner: * Check if the air filter is dirty. * Ensure that the air conditioner’s intake grille or outlet port isn't blocked. * Verify that you've adjusted the room temperature settings (thermostat) correctly. * Make sure no windows or doors are open. * If cooling, check if sunlight is entering the room (close the curtains). Also, consider if there are heating appliances, computers, or too many people in the room.

  Your Fujitsu Air Conditioner might not operate immediately because: * If the unit is stopped and restarted quickly, the compressor won't operate for about 3 minutes to prevent fuse issues. * If the electrical breaker is turned off and on again, the protection circuit will prevent operation for about 3 minutes.
