Hello, I live in a high-rise rental unit and have an air conditioner system that includes a big fan unit on the balcony outside and an outlet for the cold air mounted high up on the wall (inside, obviously). It is controlled by a remote control. I woke up this morning to find the air conditioning had failed during the night. I located the circuit breaker which appeared not to have tripped. However I cycled it, leaving it, of course, back in the on position. This did not resurrect the air conditioner. I also attempted to use the remote to start the unit, again no success. Finally,I went out on the balcony and did a crude visual examination of the fan unit and could see nothing unusual. While I have notified my landlord, I'm interested in any possible suggestions as to what might be wrong and how I might be able to resolve the problem myself. Thank you In advance for any feedback.
