International Comfort Products PGMD42G1156 Air Pressure Switch
The job of an air pressure type switch is to determine whether the primary air circulator is doing what it is supposed to do. An air pressure switch is one of the critical safety creations designed to stop injuries or explosions. A lot of switches are designed with a reset that is manual instead of automatic, which means it will have to be manually reset in order for the HVAC system to continue running.
Symptoms to Look for when your Air Pressure Switch is Needing to be Replaced
- Furnace won't operate.
- The set temp seldom fully achieved.
- Incorrect volt reading.
