LG LMU360HE Air Pressure Switch
The job of this type of switch is to sense if the blower fan is doing what it is supposed to do. Various air pressure switches can have a manual reset, which means you have to physically reset it before the system will continue its normal operation. An air pressure switch is one of the vitally important safety mechanisms designed to keep you from harm.
Signs that your System Pressure Switch will go Bad
- Incorrect volt range being used by the switch.
- The correct temperature in the house is almost never achieved.
- The furnace or AC can not operate properly.
