International Comfort Products PGF048L080F Air Pressure Switch
The primary function of the air pressure switch is to determine whether or not the primary air circulator is running. This is one of the key devices that are created to stop injuries or explosions. Some pressure switches have a manual reset feature, from which it would have to be reset manually before the system will continue its normal operation.
Symptoms to Look for when the Switch is About to Fail
- Your system doesn't achieve the desired temperature when set by the thermostat.
- Your furnace refuses ignite.
- Incorrect voltage running through the switch.
