Carrier 38HDL036 Air Pressure Switch
The reason for the existence of an air pressure type switch is to determine whether the main blower is running properly. A lot of switches have a manual reset feature, which, of course, means that it would have to be reset by hand or the whole HVAC system will not continue operation. This pressure switch is just one of the many indispensable mechanisms designed to keep your family safe and sound.
What to Look for when your Pressure Switch is Going Bad
- Furnace won't run.
- Inaccurate voltage range reading from the switch.
- HVAC system does not actually get to the right temperature.
