Bryant 348 Air Pressure Switch
The reason for the existence of the switch is to sense whether the main blower is circulating the air as it should. The majority of pressure switches are programmed with a manual reset, from which the switch will have to be manually reset before the system will continue its normal operation. This is part of a small, but important collection of aspects of the whole safety system that is intended to keep you from harm.
How do you Know when the System Pressure Switch is Failing
- The proper temp is hardly ever attained.
- Inaccurate volt range being read.
- The blower will not operate.
