Boiler changes high temp to 140

bdheat Member Posts: 6
I have seen some posts about people dealing with my same issue. Even though I set the high limit to 180, the temperature changes itself after a few cycles to shut off at 140. This is a weil McLain with economy adjust. I can fiddle with the temp and make it work again but then it always changes back to 140. No where have I seen someone get this situation rectified. Can any help with what is happening?

    If you change the setpoint to something and later come back and it's different, the two things I'd do is look to see who has access, & call tech support.

    Just looking to see if anyone else with this issue has had it fixed and what needed to be fixed.
