Nordyne E3EX-017H Air Pressure Switch
The actual job of the air pressure switch is to sense if the air blower is circulating the air as it should. Most air pressure switches may have a reset feature that is manual, by which you must manually reset it before the entire HVAC system will continue operating again. This pressure switch is one of many other devices designed to keep you from harm.
What to Look Out for when the System Pressure Switch is Failing
- Wrong voltage range reading.
- The correct temperature in the house is rarely attained.
- The blower fan will not run.
