Test the pressure switch with a Ohm meter to see if it is making contact. Make sure any condensate hoses are free of moisture and/or debris. Check for a blockage in your venting system.

Turn off power. Pull vinyl hose off pressure switch and make sure it is clear of debris/water. Turn on power. Try again.
