Carrier 38TKB060 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 circulating the air as it should. Various air pressure switches may have a reset feature that is manual, which means it would need to be reset in order for the HVAC system to continue running. This is just one of many device to keep you from harm.
Precursors that the HVAC Air Pressure Switch is Already Failing
- System does not reach desired indoor temperature.
- Wrong voltage being used by the switch.
- The blower fan refuses to function.
