LG LP120CM3 Air Pressure Switch
The job of the pressure switch is to sense whether the blower is actually running. This pressure switch is a very critical piece of the safety system that is in place to keep you safe and keep your family safe. The vast majority of pressure switches made today are programmed with a manual reset, by which you must manually reset it or the entire system will not run.
What to Look for when your Air Pressure Switch is Starting to Go
- Bad electrical voltage reading.
- The set temperature indoors is never fully achieved.
- Your furnace is unable to operate at all.
