LG LP1415GXR Air Pressure Switch
The function of the switch is to determine whether or not the primary blower is doing what it is supposed to do. Most air pressure switches can have a manual reset, from which it would have to be reset manually before you can continue using the system. This is one of many other mechanisms designed to stop injuries or explosions.
Symptoms that your System Pressure Switch has Failed
- Your furnace is unable to ignite the gas.
- The right temp is hardly ever fully achieved.
- Bad voltage being used by the switch.
