Hello Everyone! For about the last two years the AC in our 2014 Puma travel trailer will only operate on high fan speed. As long as we start the fan on high then switch over to cool the AC run perfect and cools the camper as it should. If we switch it to low or auto, we can hear a click in the control board (above the filter inside the camper) but the fan will shut off. If we try to start it on low or auto, we get the same click and no start. If we wait a few seconds, we can hear the compressor humming but no fan. I have tried switching out the thermostat but that didn't help. I'm wondering where to go from here... Control board, fan motor, or something else?? Any help would be great!
