    Westinghouse furnace

    Having an issue with a high efficiency Westinghouse furnace tripping the manual reset limit mounted to the top of the sealed burner box.

    That’s interesting. I can think of half a dozen reasons off the top of my head. Unfortunately you give no one anything to go on. Sounds like you should get that problem fixed though. Could wind up being serious.

    How many times must one fix something before it is fixed?

    That usually trips because there is a blockage in the heat exchanger or vent system. One would think the air proving switch would trip but that is rarely the case unless the flue is 100% plugged.

    It’s a very short concentric flue. I took it apart and couldn’t find any blockage. In my experience there would be some sort of discoloring of the inside of the burner box. It looks great. The only other thing I can think of is the inducer. I had a unit years ago doing the same thing and changing the inducer fixed it.

    It's rare but the limit could be faulty I had one that would trip almost as soon as the metal got warm to the touch. How long between limit trips? Also who is making Westinghouse is it a rebadged York or Goodman?

    I’m gonna replace the limit and see what happens since I can’t find anything else . It says Westinghouse. I’m not sure if they’re independent or owned by another manufacturer.
