International Comfort Products N9MP2080F16A2 Air Pressure Switch
The function of the pressure switch is to determine whether the primary blower is doing what it is supposed to do. An air pressure switch is one of the key mechanisms designed to keep you safe. Most air pressure switches are programmed with a manual reset, which forces the system to be reset physically or the whole HVAC system will not continue operation.
Red Flags that your Air Pressure Switch is in Need of Replacement
- Incorrect voltage being read from the pressure switch.
- The correct temp is almost never reached.
