  If your Tosot Air Conditioner isn't cooling well, start by cleaning or replacing the air filter. Also, reduce any heat sources or the number of people in the room, and ensure doors and windows are closed. Check for obstructions at the air intake or outlet and lower the set temperature. If problems persist, there may be a refrigerant leak or an issue with the room temperature sensor, which would need to be checked.

  If your Tosot Air Conditioner starts and then stops, check for any obstacles in front of the condenser and remove them. Also, the control loop might be abnormal and requires inspection. If you're using cooling operation when the outdoor temperature is above 46.1°C (115?), switch to a more suitable mode for that temperature.

  If your Tosot Air Conditioner runs for a bit and then shuts down, it could be due to a few reasons. Make sure there's nothing blocking the condenser. It's also possible that the control loop is malfunctioning and needs to be checked. Finally, if you're using the cooling function when it's hotter than 46.1°C (115°F) outside, that could be the problem. Avoid using cooling operation above the specified outdoor temperature.

  Andrew SandersAug 20, 2025
  If your Tosot Air Conditioner isn't heating well, start by cleaning or replacing the air filter if it's dirty. Make sure all doors and windows are firmly closed. Try increasing the set room temperature. If these steps don't improve heating, there might be a refrigerant leak, which needs to be checked. Also, the unit might not perform well if the outdoor temperature is below -5°C (23°F), so avoid operating it under these conditions. Finally, the control loop may be abnormal and should be checked for abnormalities.

  If your Tosot Air Conditioner won't start, first check that it's properly connected to the power supply. If the leakage switch is tripping, there may be an electrical leak. Also, ensure the operating keys aren't locked. If none of these resolve the issue, there might be a failure in the control loop, which requires checking.

  If your Tosot Air Conditioner's heating isn't effective, begin by cleaning or replacing the air filter. Make sure that doors and windows are firmly closed to prevent drafts. Also, increase the set room temperature. If the issue continues, there could be a refrigerant leak or the outdoor temperature might be below -5°C (23?). In this case, adjust the operation mode accordingly. Finally, an abnormal control loop could be the cause, which requires checking.

  If your Tosot Air Conditioner isn't starting, the issue might be simple. First, check that it's properly connected to the power supply. If the leakage switch is tripping, it indicates an electrical leakage that needs to be inspected. Also, make sure the operating keys aren't locked; if they are, unlock them. Finally, a failure in the control loop could also prevent the unit from starting, so inspect it for failures.
