Why is my Toshiba Air Conditioner not cooling or warming sufficiently?
- MMatthew PalmerAug 10, 2025
Insufficient cooling or warming can occur for several reasons. Check if the air intake or discharge of the outdoor unit is obstructed and ensure it is not. Close any open doors or windows. Clean or replace the air filter if it's clogged with dust. Adjust the discharge louver to the appropriate position. Ensure the operation mode is set to an appropriate cooling or heating mode, and not just 'FAN' with a low setting. Adjust the setup temperature to the desired level. Make sure that only one mode (COOL or HEAT) is selected. Verify that the outdoor temperature is within the acceptable operation range.
