Why Fujitsu ABTF14LAT airflow is weak or stops?
Weak or absent airflow in your Fujitsu Air Conditioner can occur due to several reasons:* During the start of heating operation, the fan speed is temporarily very low to allow internal parts to warm up.* If the room temperature exceeds the thermostat setting during heating, the outdoor unit will stop, and the indoor unit will operate at a very low fan speed. Increase the thermostat setting if you want more heat.* The unit will temporarily stop (for 7-15 minutes) during heating for automatic defrosting. The OPERATION lamp will flash during this time.* The fan might run at a very low speed during dry operation or when the unit monitors the room temperature.* In monitor AUTO operation, the fan will operate at a very low speed.

Why is my Fujitsu ABTF14LAT cooling or heating poorly?
Several factors can impact cooling or heating performance. Check if the air filter is dirty, or if the air conditioner’s intake grille or outlet port is blocked. Ensure the thermostat is set correctly and that no windows or doors are open. For cooling, close curtains if sunlight enters the room. Also, consider if there are heat-generating appliances or too many people in the room. Finally, check if the unit is set to QUIET operation.
