Carrier 58MVP080F15120 Air Pressure Switch
The main job of this type of switch is to determine whether the blower is doing what it is supposed to do. This is part of a small, but important collection of hardware devices made to keep everyone in the house safe. Most air pressure switches may have a manual reset, from which the switch will have to be manually reset or else the system will cease to function.
How to Know when the System Pressure Switch is Beginning to Fail
- The desired temp is hardly ever attained.
- Wrong electrical voltage being read from the pressure switch.
- The blower fan is unable to run.
