International Comfort Products GPCM36L100F Air Pressure Switch
The main job of the pressure switch is to sense whether the air blower is running. This switch is just one of many mechanisms designed to stop injuries or explosions. A good number of pressure switches today are programmed with a manual reset, which means you have to physically reset it in order for the HVAC system to continue running.
Red Flags that your HVAC Air Pressure Switch will Soon Fail
- Incorrect voltage being used by the switch.
- The furnace will not operate.
- Your system doesn't get to the correct indoor temperature.
