Why won't the compressor start on my Toshiba MMU-UP0051MH-E(TR) Air Conditioner?

If the Toshiba Air Conditioner compressor won't start, it might be due to the 3-minute protective function. Wait 3 minutes before restarting. Alternatively, check if the room temperature has reached the set temperature while in standby. Also, ensure the unit is not in timer or fan mode; switch to cooling or heating. Finally, allow the unit time to complete its initial communication.
