Haier HR30D2VAR Air Pressure Switch
The actual job of the pressure switch is to determine whether or not the blower is circulating the air as it should. The air pressure switch is a very critical piece of all the safety features in today's HVAC systems that is in place to keep you safe and keep your family safe. A lot of switches are equipped with a manual reset feature, from which the switch will have to be manually reset before the entire HVAC system will continue operating again.
Signals that the Pressure Switch will Soon Fail
- The right indoor temperature is hardly ever reached.
- Incorrect voltage running through the pressure switch.
- The furnace or AC will not function properly.
