LG ARNU423TMC2 Air Pressure Switch
The function of the pressure switch is to determine whether or not the main blower is actually running. Some pressure switches are equipped with a manual reset feature, from which the switch will have to be manually reset before the system will continue its normal operation. This is part of a small, but important collection of aspects of the whole safety system that is intended to keep you from harm.
Signs to Look Out for when the HVAC Air Pressure Switch is Needing to be Replaced
- Wrong volt being read from the pressure switch.
- The correct temperature in the house is never fully achieved.
- The furnace is unable to run.
