You need to hold the switch down until the generator stops running. If that doesn't work you probably have a bad switch. I have a 3rd switch located on the control panel in the bedroom. Not sure about yours. The AC units will not start immediately. It takes a couple of minutes. Switch your thermostat to AC and set the temperature several degrees below the inside temp and wait at least two to three minutes to see if they will start. You must have both AC units switched on for them both to work. You should see a 1 or 2 or both numbers on the thermostat. Also, if you have heat pumps and the outside temp is in the mid to low 30's they will not start and try to switch to the propane furnace. Some of this is assumptions based on the operation of my 2006. However, my 2002 also worked the same way.
