Where is "western Michigan"? When I think about it, I guess you could consider the U.P. as "western" Michigan as well, or are you in the lower peninsula on the western side? (just curious, I love the U.P.)
Right, Gilly, UP is beautiful. Western Michigan nomally refers to the area in the greater Grand Rapids. Actaully the most western part of MI is in the UP, right above your state of WI.
If you push down the "O" button, it should stay down and shut off the system, you shouldn't have to hold it down manually. Sounds like probably the problem is a mechanical defect in the push button panel.
You are right. There must be a mechanical problem in the push butons. The problem is not that big to bother me now. But someday I will take the poush button out and take a look.
