SPT WA-1240H Air Pressure Switch
The job of an air pressure type switch is to see if the blower is running. Some pressure switches have a manual reset feature, which means it would need to be reset or the whole HVAC system will not continue operation. This switch is one of many other devices that are created to keep everyone in the house safe.
Clues that your Pressure Switch is Failing
- Wrong electrical voltage being read.
- The correct temperature indoors is rarely attained.
- The furnace won't ignite the gas.
