Carrier 58MXB080F10120 Air Pressure Switch
The primary function of this type of switch is to sense whether the primary blower is running properly. The vast majority of pressure switches made today are constructed with a manual reset, which makes you reset it by hand before the HVAC system will continue. The air pressure switch is part of the safety system that is in place to keep you safe from injury or explosions.
Signals that the System Pressure Switch is Starting to Fail
- Inaccurate volt being read from the pressure switch.
- Your furnace will not operate.
- The proper indoor temperature is hardly ever reached.
