I just had a 95% ducane furnace installed. along with a new thermostat wire and thermostat. The furnace refuses to run the way I think it should. It shuts off usually in the middle of the night and wont come back on without turning power off. it goes out on two codes either pressure switch open with inducer on(code 3) or pressure switch cycle lock out(code 6). and the furnace wont stay on until the set point on the thermostat is reached either.
