i bought 3 microwave glass trays / plates at a yard sale, how do you determine what models they go to? i tried typing in what information there is on the glass plates but it didn't reall help, what do you think?

. You may be able to find a part number molded into the tray and Google it. I couldn't find any numbers on the one in my microwave.

They're unfortunately not universal either. The most common is the 3-tooth cog on the bottom centre. Others are totally flat and rely on the plastic roller-base to interface with the turntable motor. the important parts to matching would be cog-interface, diameter of the smooth-roller bearing surface, and overall diameter.

Why did you buy them? You're unlikely to find out unless you have the chance to actually try fitting them. L
