LG LP1215GXR Air Pressure Switch
The main function of the switch is to see if the air blower is running. Some pressure switches are constructed with a manual reset, which means you have to physically reset it in order for the HVAC system to continue running. This is one of the critical facets of the HVAC safety checks that are dedicated to keep you safe.
Symptoms that the Air Pressure Switch is Already Failing
- The proper temp is almost never attained.
- Inaccurate volt range reading.
- Furnace will not operate at all.
