Friedrich MW12C1H Air Pressure Switch
The main function of the air pressure switch is to see if the main blower is circulating the air as it should. This switch is one of the vitally important safety device to keep everyone in the house safe. Some different switches may have a reset feature that is manual, which makes you reset it by hand before the entire HVAC system will continue operating again.
What Signs are Present when the Switch is About to Fail
- Wrong volt running through the pressure switch.
- The right temperature is rarely reached.
- Furnace will not ignite.
