International Comfort Products N2A348AKA200 Air Pressure Switch
The job of an air pressure type switch is to sense whether the air blower is circulating the air as it should. An air pressure switch is one of the critical mechanisms designed to keep you safe. Most air pressure switches are equipped with a manual reset feature, which means you have to physically reset it in order for the HVAC system to continue running.
Symptoms to Look for when the HVAC Air Pressure Switch is About to Fail
- Bad voltage being read.
- The desired temperature indoors is hardly ever achieved.
- The furnace is unable to ignite.
