International Comfort Products 84 SERIES Air Pressure Switch
The function of this type of switch is to sense whether the air blower is circulating the air as it should. An air pressure switch is just one of the many indispensable devices designed to stop injuries or explosions. Some pressure switches are designed with a reset that is manual instead of automatic, which means it would need to be reset or the whole HVAC system will not continue operation.
Symptoms to Look for when your Pressure Switch is Starting to Go Bad
- The blower fan refuses to function properly.
- Wrong voltage range running through the switch.
- The desired temperature in the house is never reached.
