#138174, "RE: New thermostat is failing open?" In response to In response to 1 Oct-30-13 09:05 PM by ez
That's ok guys I'll just keep talking to myself ....

.... anyways I just realized an overpressurization in the bypass line would push the valve in the wrong direction, since it opens *towards* the motor, thus closing the valve. I think it might be due to cheap autozone failsafe thermostats. I think mine failed open permanently with 24 hours. This guy seemed to have the same problem, but his thread never had a resolution ->http://forums.2gnt.com/dcboard.php?az=show_topic&forum=5&topic_id=132505&mode=full
