  If your Daikin Air Conditioner operation stops suddenly and the OPERATION lamp blinks, ensure the air filters are clean and that nothing is blocking the air inlet or outlet of the indoor and outdoor units. Clean the filters or remove any obstacles, then turn the breaker OFF and back ON. Try operating the air conditioner with the remote controller again. If the lamp continues to blink, contact the service shop where you purchased the air conditioner.
