What to do if my Daikin Air Conditioner operation stops suddenly and the OPERATION lamp flashes?

If the Daikin Air Conditioner operation suddenly stops and the OPERATION lamp flashes, several factors could be at play. First, ensure the air filters are clean. Next, check for any obstructions blocking the air inlet or outlet of either the indoor or outdoor units; if there are any obstacles, turn off the breaker, remove them, and then turn the breaker back on before attempting to operate the unit with the remote. In multi-systems, confirm that all indoor units are set to the same operation mode. If using AUTO mode, temporarily switch all indoor units to either COOL or HEAT to see if the issue resolves.
