I purchased a new Goodman Split system (2.5 ton a/c with gas furnace GMNT model). After installing the airhandler blower comes on(but not the furnace exhaust vent blower) and runs constantly without the thermostat even being connected flashes open limit switch. I also don't get 24 volts from any of the wires from the circuit board thermostat leads. If I jumper the thermostat directly to the transformer the code stops and the condensor runs. I just did this for atest of the condensor. Could the Ciruit board be bad??? or just a limit switch??? Help please!!!!!!!!!!!
