Green light flashes 3 times will not operate

Yesterday my air conditioning was working fine, this morning I went to turn it on and all it will do is flash the green timer light three times. I had tried turning it off at the wall outside, making sure the timer is turned off, reset the remote and nothing seems to help. any ideas would be helpful.

We had a similar problem. The timer light would blink 3 times, pause, then blink 3 times again, pause, and so on. The fan was blowing lots of air out, but the air was not cold. The operation light was off.

The technician came and fixed it for free, since it's actually easy to fix. He went to our circuit-breaker box, and cut power (from the box) to the air conditioners for 30 seconds. Then, he restored power - problem fixed!

It's apparently because the air con goes into a "safety" mode when there's a power surge.

I had the same problem. The heater did not work in heating mode. However it was OK in air-conditioning mode. The operation light and the timer light blink twice and then the operation light blinks for 5 times followed by few seconds non blinking, then the cycle repeats again. I have read on the internet that you better unplug the power cord and then plug it again so that the heater re-sets itself. My only problem was that my heater is directly plugged to the power with no visible plug. So I went to the main distribution board and put off the power for about 20 seconds for the whole home. HOORAY!! The heater worked after that.
