International Comfort Products GDL100N16A3 Air Pressure Switch
The actual job of the pressure switch is to determine whether the blower fan is on and running. The vast majority of pressure switches made today have a manual reset feature, which means it will have to be manually reset or else the system will cease to function. This is part of a small, but important collection of aspects of the whole safety system that is intended to keep you from harm.
Signs that the Pressure Switch is Beginning to Go
- HVAC system can not operate.
- The desired temperature is never attained.
