International Comfort Products T8MPN150J20B1 Air Pressure Switch
The main function of the switch is to determine whether or not the blower fan is actually running. Various air pressure switches are designed with a reset that is manual instead of automatic, which, of course, means that it would have to be reset by hand before you can continue using the system. This is one of the key devices that are created to keep you from harm.
Symptoms that the Air Pressure Switch is About to Fail
- The set indoor temperature is never fully attained.
- Incorrect volt range being read.
- The furnace will not ignite the gas.
