International Comfort Products PGMD24G0905 Air Pressure Switch
The main job of the pressure switch is to see if the air blower is actually running. This is just one of many mechanisms designed to keep your family safe and sound. The vast majority of pressure switches made today are issued with a manual reset feature, which means you have to physically reset it or the whole HVAC system will not continue operation.
Signs that your HVAC Air Pressure Switch is Beginning to Go Bad
- The expected temperature is hardly ever reached.
- The blower fan can not function properly.
- Wrong voltage being read from the pressure switch.
