International Comfort Products GPCM60K140F Air Pressure Switch
The main job of the switch is to determine whether or not the blower is running. This is just one of many device to keep you from harm. The majority of pressure switches are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset before the HVAC system will continue.
How do you Know when the Switch has Gone Bad
- Inaccurate volt running through the switch.
- The expected temp is rarely achieved.
- The blower will not run.
