International Comfort Products NAC236AKA1 Air Pressure Switch
The function of the air pressure switch is to see if the blower is running properly. Some particular air pressure switches can have a manual reset, which means it would need to be reset or the whole HVAC system will not continue operation. This is one of many other aspects of the whole safety system that is intended to keep everyone in the house safe.
Signs that the Switch is Already Failing
- The blower fan will not run correctly.
- Incorrect voltage running through the switch.
- The proper temp is rarely fully achieved.
