Rooftop AC Question
Yahoo Message Number: 111542
I have 3 rooftop units and one of them (the center one) stopped working. On the coleman thermostat, the unit just disappeared. It doesn't show up for Heat Elec., AC or Heat Gas…. so I'm thinking that the board that controls the AC unit (that is mounted on the AC unit) is bad. Is this board user replaceable (I'm 300 miles from anywhere that could fix it) and where is the board? I'm thinking its on the RT unit itself, but I'm wondering if you access from inside the coach or from the roof? If anybody has replaced these boards, let me know. Any other troubleshooting, eg. where to test for power, etc. would be great. I have reset the breakers on all three units and have reset the coleman thermostat and that hasn't cleared the problem.
