Carrier 50XL-A42 Air Pressure Switch
The reason for the existence of an air pressure type switch is to determine whether or not the primary blower is actually running. This is one of the vitally important safety hardware devices made to keep you from harm. The vast majority of pressure switches made today are programmed with a manual reset, which means you have to physically reset it or else the system will cease to function.
How to Know when your Pressure Switch is About to Fail
- Wrong voltage range being read from the pressure switch.
- The desired temperature indoors is never achieved.
- The furnace will not ignite.
