Carrier Ducted Remote Control Air Conditioner

Question: When we attempt to turn on the ac, green light comes on, flashes five times, goes off, comes back on, flashes five time and the ac never comes on. What is it trying to tell us. Other ac is working fine.

Robbie: The computer is trying to say, "Hey, something went wrong last time you used me so I shut everything off." I'm just kidding. On a more serious note, the computer has gone into default because something went wrong the last time you used the AC. The most common of these problems is unplugging the motor home or trailer while the AC was running.

A more serious problem could exist like the compressor went bad.

All you need to do is remove 12 volt power to the computer that has the light flashing 5 times. You can pull a fuse in your power center or with the 110 volt disconnected, turn off the 12 volt kill switch or disconnect the battery for a second. This will reset the computer and the AC will now come on when you have 110 volt and the 12 volt to the PC Board. If the problem was as simple as you unplugged the power while the AC was running then the problem is fixed (Don't do that anymore).

If the problem was more serious the AC might still come on but the Computer will go into default again and you'll need to have the system tested by a qualified tech.

Good luck and let me know what happens,
Robbie
