Trane PTHD150 Air Pressure Switch
The primary function of an air pressure type switch is to sense whether the primary blower is actually running. An air pressure switch is one of the critical aspects of the whole safety system that is intended to stop injuries or explosions. A lot of switches are equipped with a manual reset feature, which means it will have to be manually reset before the HVAC system will continue.
Symptoms to Look for when the System Pressure Switch has Failed
- The blower can not operate.
- Inaccurate electrical voltage running through the pressure switch.
- The desired temperature indoors is never achieved.
