International Comfort Products NNE075B12G1 Air Pressure Switch
The primary function of the pressure switch is to sense whether the blower is running properly. An air pressure switch is part of a small, but important collection of mechanisms designed to keep you safe. A good number of pressure switches today are designed with a reset that is manual instead of automatic, which means it would need to be reset or the whole HVAC system will not continue operation.
Clues that your Pressure Switch is About to Fail
- System does not reach desired temperature when set by the thermostat.
- Inaccurate volt range running through the pressure switch.
- Furnace will not ignite the gas.
