SPT TN-09E Air Pressure Switch
The main job of the switch is to see if the main blower is on and running. Some different switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically or else the system will cease to function. This is one of the vitally important safety mechanisms designed to keep your family safe and sound.
Signs to Look Out for when the System Pressure Switch is Going Bad
- Wrong voltage range running through the switch.
- HVAC system is unable to operate properly.
- HVAC system does not achieve the desired temperature as set by the thermostat.
