Friedrich MW36C3F Air Pressure Switch
The main function of the switch is to determine whether or not the main blower is doing what it is supposed to do. This pressure switch is one of many other facets of the HVAC safety checks that are dedicated to keep you safe. The vast majority of pressure switches made today 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.
Important Signs that the System Pressure Switch is Starting to Go
- The blower can not run.
- The desired temperature in the house is almost never achieved.
- Wrong volt range being read from the pressure switch.
