What to do if my Toshiba RAC-WK0811ESCWU Air Conditioner does not start?
- J
  John HughesAug 20, 2025
  If your Toshiba Air Conditioner doesn't start, check the following: * Ensure the wall plug is firmly pushed into the outlet. * Replace any blown fuse with a time-delay type or reset the circuit breaker if it has tripped. * If the plug current device has tripped, press the RESET button. * Make sure the power is ON and set to your desired settings. * If you recently turned the unit off and on, wait 3 minutes before restarting it.

Why Toshiba Air Conditioner does not start?
- M
  Mr. Spencer CampbellAug 22, 2025
  Your Toshiba Air Conditioner might not be starting due to several reasons: the wall plug may be disconnected (push it firmly into the outlet), a house fuse might be blown or the circuit breaker tripped (replace the fuse or reset the breaker), the plug current device may have tripped (press the RESET button), the power might be off (turn it ON and set to the desired setting), or the unit was turned off and then on too quickly (wait 3 minutes before restarting).

Why is my Toshiba Air Conditioner turning on and off rapidly?
- M
  Micheal MartinezAug 25, 2025
  Your Toshiba Air Conditioner might be turning on and off rapidly because of a dirty air filter restricting airflow (clean the air filter). Another reason might be extremely hot outside temperatures, in which case you should set the FAN speed to a higher setting to increase airflow past the cooling coils.

  If your Toshiba Air Conditioner is cooling, but the room is too warm and there's no ice forming on the cooling coil, consider these points: * Ensure the air filter is clean. Please, refer to the Care and Cleaning section for instructions. * Lower the temperature setting. * Adjust the air directional louvers for improved air distribution. * Remove any obstructions like drapes, blinds, or furniture from the front of the unit. * Close any open doors, windows, or registers. * If the unit was recently turned on in a hot room, allow extra time for the unit to remove stored heat from the surroundings.

  If your Toshiba Air Conditioner is cooling, but the room is too warm and ice is forming on the cooling coil, consider the following: * If the outdoor temperature is below 64°F (18°C), this may be the cause. * Clean the air filter. Please, refer to the Care and Cleaning section. * If the thermostat is set too cold for night-time cooling, increase the temperature setting. * To defrost the coil, set the unit to FAN ONLY mode.

Why doesn't the air from my Toshiba Air Conditioner feel cold enough?
- J
  Jessica AndersonAug 31, 2025
  If the air from your Toshiba Air Conditioner doesn't feel cold enough, consider the following: * Cooling may not occur until the room temperature rises above 62°F (17°C) if the room temperature is below this. * Straighten the temperature sensing element tube away from the cold coil located behind the air filter if it's touching it. * Reset to a lower temperature. * If the compressor shut off by changing modes, wait approximately 3 minutes and listen for the compressor to restart when set in the COOL mode.

  Lindsay EdwardsSep 5, 2025
  If your Toshiba Air Conditioner is cooling but the room remains too warm without ice forming, consider the following: ensure the air filter is clean (refer to the Care and Cleaning section), set the temperature lower, properly position the air directional louvers for better air distribution, clear any blockage in front of the unit (drapes, blinds, furniture, etc.), close any open doors, windows, or registers, and allow additional time for the unit to remove stored heat from the room if it was recently turned on.
