SPT WA-1220H Air Pressure Switch
The function of this type of switch is to determine whether the primary air circulator is running. A good number of pressure switches today are designed with a reset that is manual instead of automatic, by which you must manually reset it or else the system will cease to function. This is one of the vitally important safety hardware devices made to stop injuries or explosions.
Important Signs that the Switch is in Need of Replacement
- HVAC system will not run.
- Inaccurate volt range reading.
- System does not reach desired temperature.
