Can't believe it

So I change out vac hose on my 07 Mt.Vernon no big deal,Worked just fine.So I figure might as well change or blow out the hose on the 09 stove. I take hose off and there's a little saw dust on the end.I blow out hose and put back on turn stove on get error vacuum switch code.Wtf R U kidding me all I did was clean out hose.So I bypass switch with a jumper and it's all good.How could cleaning out the vac hose cause the switch to go bad just like that?WELL that's a mystery to me .

New vac switch and good to go.I did try the old vac switch on the other stove and it came up with same code so I knew for sure that's what it was.

Dissected old vac switch and all it is a rubber diaphragm with a mechanical metal arm.Original was all metal casing,New one is plastic. For $62.00 they are making a killing on this part that probably cost $20.00 to make..

Yea ya think 110% profit.At least the old one was made in US not sure if new one is.

Sure looks like it is
