What is a permanent fix for the 31 error code. Service tech has been here 3 times in 4 weeks to blow out lines on a Carrier Weathermaker 9200?

According to the manual for the Carrier Weathermaker 9200 an error code 31 means pressure switch not closed. The manual suggests:
Check to make sure that all PVC pipes leading into the combustion-air intake and vent/exhaust are free from any cracks and sags. Also check the combustion-air intake and vent/exhaust pipes on the outside of your home for blockage.
