Mitsubishi MUY-GE15NA Air Pressure Switch
The reason for the existence of the pressure switch is to sense whether the primary blower is actually running. The majority of pressure switches are equipped with a manual reset feature, which makes you reset it by hand or the whole HVAC system will not continue operation. This switch is part of a small, but important collection of devices designed to keep you from harm.
Precursors that the HVAC Air Pressure Switch is Beginning to Fail
- The set temp is almost never fully attained.
- Wrong electrical voltage reading from the switch.
- Furnace refuses ignite the gas.
