Haier HPRD12XC7 Air Pressure Switch
The primary function of this type of switch is to sense if the main blower is actually running. This pressure switch is one of the key devices designed to keep you safe. The vast majority of pressure switches made today are designed with a reset that is manual instead of automatic, which makes you reset it by hand or else the system will cease to function.
Warning Signs that the System Pressure Switch has Gone Bad
- Incorrect volt reading.
- System does not get to the correct indoor temp.
- The blower can not function properly.
