International Comfort Products TCA436AKA1 Air Pressure Switch
The main job of an air pressure type switch is to sense if the primary blower is running properly. A lot of switches have a manual reset feature, which forces the system to be reset physically before the entire HVAC system will continue operating again. This switch is a very critical piece of the collection of safety devices in place to keep you safe and keep your family safe.
What to Look for when the System Pressure Switch is Starting to Fail
- Bad volt running through the switch.
- Your furnace won't run.
- The set temperature indoors is hardly ever fully attained.
