LG LP150CED Air Pressure Switch
The job of the pressure switch is to sense if the blower fan is running properly. This pressure switch is a very critical piece of the safety system in place to keep you safe from potential hazards in the house. The majority of pressure switches are constructed with a manual reset, which makes you reset it by hand or else the system will cease to function.
Warning Signs of a Broken Pressure Switch
- Your furnace will not run.
- Incorrect electrical voltage being used by the switch.
- The correct indoor temperature is rarely achieved.
