Carrier 48XZ042060300 Air Pressure Switch
The function of this type of switch is to sense if the main blower is blowing air. This is one of the critical aspects of the whole safety system that is intended to keep you from harm. The vast majority of pressure switches made today have a manual reset feature, which forces the system to be reset physically in order for the HVAC system to continue running.
Symptoms that the Switch is Starting to Go Bad
- Wrong volt reading.
- The blower will not run correctly.
- The right temperature indoors is hardly ever achieved.
