Haier HPR09XC7 Air Pressure Switch
The main function of the air pressure switch is to see if the blower is circulating the air as it should. Various air pressure switches can have a manual reset, which forces the system to be reset physically before the system will continue its normal operation. An air pressure switch is just one of the many indispensable mechanisms designed to keep you from harm.
Important Signs that the System Pressure Switch is About to Fail
- Bad volt reading from the switch.
- The set indoor temperature is never fully attained.
- The blower fan will not function.
