LG AMNH123DEA0 Air Pressure Switch
The job of this type of switch is to sense whether the main blower is doing what it is supposed to do. An air pressure switch is one of many other device to stop injuries or explosions. Some particular air pressure switches are equipped with a manual reset feature, from which it would have to be reset manually or the entire system will not run.
What Signs are Present when the Switch is Failing
- The furnace won't ignite the gas.
- The proper temperature in the house is rarely reached.
- Wrong volt range reading.
