International Comfort Products TCA236AKA5 Air Pressure Switch
The function of an air pressure type switch is to determine whether the blower is doing what it is supposed to do. This switch is just one of many facets of the HVAC safety checks that are dedicated to stop injuries or explosions. The vast majority of pressure switches made today have a manual reset feature, which means you have to physically reset it or the whole HVAC system will not continue operation.
What to Look Out for when the System Pressure Switch is About to Fail
- The expected temperature is almost never fully attained.
- Bad voltage range running through the switch.
- Your heating and cooling system is unable to run.
