Hello all. I have an MG100 combo & when I turn it on the fan makes a lot of noise for about 40 seconds or so and then quiets. I have searched the net & found it to be a common problem with the MG series. I have seen comments that some just ignore it (as I have untill now), some hit it with WD40, and some have replaced it. I would like to at least try the WD40 & if that does not work, replace it. Does anyone know how I get it opened to do that or have any other thoughts/suggestions on the problem? I started to pull some screws out this morning & then backed off & figured I'd try to get some input 1st. Thanks.
