International Comfort Products NTGM Air Pressure Switch
The actual job of the air pressure switch is to determine whether or not the blower fan is running properly. The air pressure switch is part of the collection of safety devices in place to keep you safe from potential hazards in the house. The majority of pressure switches are programmed with a manual reset, by which you must manually reset it before the entire HVAC system will continue operating again.
Symptoms to Look for when the HVAC Air Pressure Switch has Failed
- The desired temperature indoors is rarely reached.
- Bad voltage reading.
