SPT WA-1230H Air Pressure Switch
The main job of this type of switch is to determine whether the primary air circulator is circulating the air as it should. This pressure switch is just one of many aspects of the whole safety system that is intended to keep your family safe and sound. A good number of pressure switches today are programmed with a manual reset, which, of course, means that it would have to be reset by hand before the HVAC system will continue.
Important Signs that the Switch is About to go Bad
- The expected temperature seldom fully achieved.
- Bad voltage being used by the switch.
- The furnace or AC will not operate.
