Samsung UQB09JJWC Air Pressure Switch
The job of this type of switch is to see if the primary air circulator is running. This is one of the most crucial device to keep you from harm. A lot of switches are equipped with a manual reset feature, which forces the system to be reset physically or the whole HVAC system will not continue operation.
Warning Signs that the Air Pressure Switch is Already Going Bad
- Wrong volt reading from the switch.
- The expected temperature indoors is never reached.
- The blower fan is unable to run.
