International Comfort Products PGMD48G1356 Air Pressure Switch
The reason for the existence of the air pressure switch is to figure out if the primary blower is on and running. The vast majority of pressure switches made today are constructed with a manual reset, which means you have to physically reset it or the whole HVAC system will not continue operation. This switch is one of the vitally important safety hardware devices made to keep everyone in the house safe.
Symptoms that your System Pressure Switch is Beginning to Go Bad
- Wrong volt range running through the switch.
- System does not achieve the desired temperature.
