International Comfort Products HAC218AKA1 Air Pressure Switch
The actual job of the switch is to sense whether the primary blower is actually running. A good number of pressure switches today may have a reset feature that is manual, which means it will have to be manually reset before the system will continue its normal operation. This is one of the key devices designed to stop injuries or explosions.
What to Look Out for when the System Pressure Switch has Failed
- Bad volt range being read.
- Your furnace won't run.
- The proper temp seldom fully achieved.
