I have a Goodman GMP075-3 furnas. I had a blink code last week for the gas valve, which I replaced. Then I had a code for the pressure switch, which I replaced! Before I replaced the switch it would still run but it would blow cold air. Now that I have put the new pressure switch on now it does nothing but click and then blink 3 blinks on the board. No fans start no burners light no nothing!! I have cleaned my port that goes into the blower. I have done everything I know to do. Do I need a new control board?
