LG AMNH093D4A0 Air Pressure Switch
The actual job of the switch is to sense if the air blower is doing what it is supposed to do. An air pressure switch is one of the critical devices that are created to stop injuries or explosions. Some pressure switches are constructed with a manual reset, which forces the system to be reset physically in order for the HVAC system to continue running.
Symptoms to Look for when the Switch has Failed
- The set temperature indoors is rarely fully attained.
- Inaccurate volt reading.
- HVAC system is unable to function properly.
