How to improve cooling performance of my Fujitsu AOTS18LDC?
If your Fujitsu Air Conditioner isn't cooling well, check these potential causes: * Ensure the air filter is clean. * Make sure the intake grille or outlet port isn't blocked. * Verify the thermostat is set correctly. * Close any open windows or doors. * During cooling, block direct sunlight with curtains and reduce heat-generating appliances or the number of people in the room. * Check if the unit is set to SUPER QUIET operation.
Why is water produced from the outdoor unit of my Fujitsu AOTS18LDC Air Conditioner?
During heating operation, water may be produced from the outdoor unit of your Fujitsu Air Conditioner due to the automatic defrosting operation.
Why is the airflow weak or stopping in my Fujitsu AOTS18LDC?
Weak airflow or complete stops in your Fujitsu Air Conditioner can happen for several reasons: * When heating starts, fan speed is temporarily low to warm internal parts. * During heating, if the room gets too warm, the outdoor unit stops, and the indoor unit runs at low fan speed. Set the thermostat higher if you want more heat. * The unit will temporarily stop for 7-15 minutes during heating for automatic defrosting; the OPERATION lamp will flash. * The fan may operate at very low speed during Dry operation or when monitoring room temperature. * During SUPER QUIET operation, the fan runs very slowly. * In monitor AUTO operation, the fan also runs at a very low speed.

Also, after disconnecting and reconnecting the power, a protection circuit may prevent operation for about 3 minutes.
