International Comfort Products TCA442AKA1 Air Pressure Switch
The main function of the switch is to figure out if the blower fan is circulating the air as it should. An air pressure switch is one of the key devices that are created to keep you safe. The majority of pressure switches are equipped with a manual reset feature, which forces the system to be reset physically or the whole HVAC system will not continue operation.
Warning Signs that the System Pressure Switch is Starting to Fail
- System does not achieve the desired temperature as set by the thermostat.
- Your heating and cooling system is unable to function.
- Wrong volt being read.
