Carrier 48XZ024040300TP Air Pressure Switch
The reason for the existence of an air pressure type switch is to determine whether or not the primary air circulator is on and running. Some different switches are programmed with a manual reset, which means you have to physically reset it or the entire system will not run. An air pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep you safe.
Important Signs that the Air Pressure Switch is Already Going Bad
- The set indoor temperature seldom fully achieved.
- Bad volt reading from the switch.
- The furnace can not run.
