International Comfort Products TCA060AKA1 Air Pressure Switch
The function of the switch is to determine whether the blower fan is circulating the air as it should. The air pressure switch is a very critical piece of all the safety features in today's HVAC systems in place to keep you safe from potential hazards in the house. Some pressure switches have a manual reset feature, by which you must manually reset it in order for the system to begin normal operations again.
Signs to Look for when the Switch is on its Last Leg
- The expected temperature is rarely fully attained.
- Your furnace won't ignite.
- Wrong voltage being read from the pressure switch.
