Why is my Toshiba RAS-M18GAV-E Air Conditioner not cooling or heating properly?

  Several factors can cause poor cooling or heating performance in your Toshiba Air Conditioner. Check if the air inlet or outlet of the outdoor unit is blocked. Ensure that doors and windows are closed. A clogged air filter, incorrect louver position, or low fan speed can also affect performance. Verify that the air conditioner is not set to DRY or ECO mode, and adjust the temperature setting if it's too high (during cooling) or too low (during heating).

  If your Toshiba Air Conditioner is inoperative, first, ensure that the main power switch is turned on and the circuit breaker hasn't been activated. Check if the main power fuse has blown or if there's an electric current stoppage. Also, verify the batteries in the remote control and make sure the ON timer is not set. Note that the air conditioner may not operate for three minutes immediately after restarting or turning on due to a protective mechanism.
