Samsung EH052CAV Air Pressure Switch
The function of this type of switch is to see if the blower fan is actually running. Most air pressure switches may have a reset feature that is manual, which forces the system to be reset physically before the HVAC system will continue. An air pressure switch is one of many other mechanisms designed to keep you from harm.
Evidence of a Broken Pressure Switch
- Furnace is unable to operate at all.
- Inaccurate volt reading from the switch.
