Did you figure out why the ac wasn't responding to the remote? I am having the same problem. I just cleaned out the filters but it's still not responding to the remote. I have already tried reset button in the remote, which didn't help. I am pretty sure that the remote is not out of battery.

Set the clock time on the remote control to start operating.

if your remote get locked then simultaneously press your temperature up down keys for some time ....lock will be opened .
