International Comfort Products TXA242AKA1 Air Pressure Switch
The reason for the existence of an air pressure type switch is to figure out if the blower fan is running properly. Most air pressure switches are programmed with a manual reset, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation. This switch is part of a small, but important collection of safety creations designed to keep you safe.
Signs to Look for when the Switch is About to go Bad
- Wrong voltage being read.
- Your furnace won't ignite.
- The right temperature in the house is never fully attained.
