Lennox CB30M-51 Air Pressure Switch
The primary function of the air pressure switch is to sense if the air blower is blowing air. The vast majority of pressure switches made today can have a manual reset, which means it would need to be reset before the entire HVAC system will continue operating again. This is one of the vitally important safety aspects of the whole safety system that is intended to keep you from harm.
Signs of a Bad Air Pressure Switch
- Inaccurate volt range being read from the pressure switch.
- Your furnace is unable to ignite the gas.
- The desired temperature indoors is never fully achieved.
