  If your Saunier Duval Air Conditioner is not cooling or heating sufficiently, start by cleaning the air filter if it's dirty or obstructed. Remove any nearby heat sources if possible, and close any open doors and windows. Ensure there are no obstacles blocking the air inlet or outlet. Adjust the thermostat if it's set too high for cooling or too low for heating. Allow a few moments for the room temperature to reach the specified level.

  If your Saunier Duval Air Conditioner is providing excessive or no cooling/heating (in cooling mode), check for obstructions on the air inlet or outlet of both the indoor and outdoor units and remove any objects causing the obstruction. If the three-minute compressor protection is activated, wait for it to complete its cycle. Also, when running in DRY mode, the airflow may stop periodically to prevent excessive cooling, or when running in HEAT mode, air will not flow until it is hot enough.

  If your Saunier Duval Air Conditioner isn't working at all, several factors could be the cause. First, check if the unit is properly connected to the circuit breaker or fuse and restore the power supply if necessary. Ensure the selector is set to “I” (on) and not “0” (off). Adjust the thermostat if it's set too high for cooling or too low for heating. Replace the fuse if it has blown. If using a remote control, replace the batteries. Finally, check that the operating time aligns with the timer settings or cancel any timer settings.
