Service call for a heater not coming on. Technician arrived to find the Amana s system not responding to a call for heat. Checked the thermostat and furnace for updates and rebooted the system. The system would respond to a test call for ac through the thermostat but no heating call. The furnace would run under a call from Bluetooth. Manufacturer tech support suggested to rewire the low voltage. Moved the thermostat wire to the Eev board and the condenser wire to the furnace and the system came back on and is functioning at this time.
