    Where is the high limit switch located on a Trane XR80 furnace
    My furnace kicks the burner off when the fan starts. After 30 seconds the burner comes back on and then it runs through its cycle pretty much like it's supposed to. I was told by a Trane technician that it could either be the control panel orthe high limit switch. Where is the high limit switch located on a Trane XR80?
