LG LS-J0910HL Air Pressure Switch
The primary function of this type of switch is to figure out if the blower is on and running. A good number of pressure switches today may have a reset feature that is manual, which, of course, means that it would have to be reset by hand or the entire system will not run. This pressure switch is part of all the safety features in today's HVAC systems that is in place to keep you safe from injury or explosions.
Signs that the Switch has Failed
- The blower refuses to function.
- Incorrect electrical voltage running through the pressure switch.
- The expected temperature is rarely fully achieved.
