Haier HPRD12XC5 Air Pressure Switch
The job of an air pressure type switch is to see if the air blower is running. The vast majority of pressure switches made today are issued with a manual reset feature, by which you must manually reset it before the system will continue its normal operation. The air pressure switch is an important part of the safety system in place to keep you safe from any injuries.
Signs that the Air Pressure Switch is Beginning to Fail
- HVAC system can not run.
- HVAC system does not get to the correct indoor temperature.
- Inaccurate electrical voltage reading.
