LG LP1411SHR Air Pressure Switch
The function of an air pressure type switch is to determine whether or not the primary air circulator is blowing air. Some pressure switches are equipped with a manual reset feature, which makes you reset it by hand before you can continue using the system. This pressure switch is part of a small, but important collection of facets of the HVAC safety checks that are dedicated to keep you from harm.
Signs to Look Out for when the System Pressure Switch is Failing
- The expected temp is hardly ever achieved.
- The blower can not operate.
- Bad voltage range running through the switch.
