International Comfort Products PGS036L080F Air Pressure Switch
The reason for the existence of the pressure switch is to determine whether or not the blower is blowing air. This pressure switch is part of a small, but important collection of devices designed to keep everyone in the house safe. Some different switches are equipped with a manual reset feature, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Symptoms to Look for when your Air Pressure Switch is About to Fail
- Your system doesn't get to the correct indoor temp.
- Your furnace won't ignite the gas.
- Incorrect electrical voltage reading from the switch.
