International Comfort Products NDC7075BFA1 Air Pressure Switch
The main function of an air pressure type switch is to determine whether or not the blower fan is blowing air. Most air pressure switches have a manual reset feature, which forces the system to be reset physically before the HVAC system will continue. This pressure switch is one of the critical mechanisms designed to stop injuries or explosions.
Symptoms that your Switch is Beginning to Go
- The blower can not operate properly.
- Your system doesn't get to the correct temp according to the settings on the thermostat.
- Inaccurate voltage range being used by the switch.
