LG LMN120HE Air Pressure Switch
The main job of this type of switch is to see if the blower is on and running. A lot of switches may have a reset feature that is manual, which means it would need to be reset before the entire HVAC system will continue operating again. An air pressure switch is just one of many safety creations designed to stop injuries or explosions.
What Signs are Present when the System Pressure Switch is Beginning to Fail
- The furnace or AC will not operate properly.
- The set indoor temperature is rarely attained.
- Bad voltage range running through the switch.
