One guess would be that they installed it a little off the vertical and have tried to compensate by adjusting the hinge spring tension high to keep it closed. Accordingly, as time goes by, the tension decreases a little and it opens. Just a guess, but you can check it with a level - should be prefectly vertical. If it's off they need to reinstall it proprerly!

I just replaced the dead cd-burner drive on one of my computers, I got a lite-on DVD burner drive that does pretty much everything from newegg for like $39. There are good prices out there. I also have an external usb cd-burner that I can connect to any of my computers by usb to have an added cd-burner, I found it on a clearance rack at an electronics store for around $15. If you do not want to dig into the machine to take the old one out and install the new one you may want to get one of the external usb ones. Replacing the internal one is not difficult but does take a bit of knowledge, it is more difficult than say adding memory. Some times the doors can get off the tracks and on occasion they can be taken out and worked on and fixed but that is a big maybe! It is a good idea to never force things! Also if you use the paperclip in the little hole in the front of the drive it is usually advised to have the pc turned off and unplugged to do that, I know not everyone does that but on the directions that come with them it does say that. Guess the risk of something electrical happening is the reason.

Thanks for you reponse, kudzu9. I guess what I'm trying to get across is that it is a nuisance to have to find something to prop it open when I put in a load from the grocery store. My other refrig will reach a certain point where it will stay open until I close it past that point and then it shuts by itself. I am hoping it is just some kind of a simple adjustment to the hinges?

Yes, same here. Sharp was AMAZING and came out and fixed it. If you want to try yourself, you can just adjust the position of the switches on the sides after you pop off the panels. I almost figured it out, but watched the Sharp tech get it done in 4 minutes!
