Lennox CB29M-46 Air Pressure Switch
The actual job of an air pressure type switch is to see if the main blower is doing what it is supposed to do. The air pressure switch is a very critical piece of the safety system in place to keep you safe from injury or explosions. A good number of pressure switches today are designed with a reset that is manual instead of automatic, from which the switch will have to be manually reset in order for the system to begin normal operations again.
How do you Know when the Switch is Going Bad
- Your furnace won't ignite.
- The right temp is hardly ever fully attained.
- Wrong volt being read from the pressure switch.
