Carrier 58MXA080F14120 Air Pressure Switch
The reason for the existence of the air pressure switch is to see if the main blower is on and running. This is one of the most crucial safety creations designed to keep you safe. The vast majority of pressure switches made today are constructed with a manual reset, which forces the system to be reset physically or else the system will cease to function.
Signs of a Nearly Failed Air Pressure Switch
- The furnace refuses ignite.
- System does not get to the correct indoor temp.
- Wrong voltage range reading.
