Lennox CBX32M-018 Air Pressure Switch
The main job of this type of switch is to sense if the primary air circulator is circulating the air as it should. Various air pressure switches are constructed with a manual reset, which, of course, means that it would have to be reset by hand before the system will continue its normal operation. This is one of the most crucial mechanisms designed to keep you from harm.
Signs that your Switch will Fail Soon
- The proper indoor temperature is rarely fully achieved.
- Bad volt reading from the switch.
- The blower is unable to operate.
