Carrier FF1DNE030005AAAA Air Pressure Switch
The job of this type of switch is to sense if the primary air circulator is running properly. This is one of the vitally important safety aspects of the whole safety system that is intended to keep you safe. Some different switches may have a manual reset, from which the switch will have to be manually reset before the entire HVAC system will continue operating again.
Red Flags that your Pressure Switch is Beginning to Fail
- Wrong volt being read.
