Have not used our center AC for in the last 6 months. We have 3 AC and the center is controlled by a 5 button thermostat on zone 2. I cleaned the contacts on the 2 phone cable connectors and was,able to get the AC working for one day and then it quit. I checked the fuse in the electric control box and found it was good. The thermostat on zone 2 will illuminate and show the AC is on but will not start the unit. The thermostat will stay on for one minute and then goes blank. Zone 3 works fine on this thermostat. Do I etneed to do a reset on the thermostat? Any ideas appreciated.
