If the Harsco Industrial MACH C750 boiler shows a "check air pressure switch" warning while the inducer fan is running and the holes are clear, possible problems include:
1. The air switch is not closing when the fan is running. 2. There may be an obstruction in the intake or exhaust ducts. 3. The burner may be dirty. 4. The blower may not be operating properly.
These should be checked and corrected before resetting the boiler.
