Question About Heating System GY9S080B12UP11j
won't fire...

Had Inductor replaced 1 year ago. Today, furnace 'sometimes' won't fire and gives a trouble code of 3 flashes. I checked outside and have very good airflow from the inductor pipe. The hoses to and from the pressure switch seem good. I'm thinking pressure switch. Is this a common mode of failure?
