Broken a microwave plate and need a replacement. Not sure which one? There are four simple steps in sizing up a microwave plate correctly.
Step 1. The part number. The numbers will look a little like this: A117, 4A0, A049, H26, Y155, Y20, 569AP, L09...
If you still have the broken plate, take a look to see if there is a number cast into the plate. For example A117. Otherwise do a internet search for the model of your oven and try to source the microwave plate number. The numbers will look a little like this: A117, 4A0, A049, H26, Y155, Y20, 569AP, L09...
Step 2. The outside diameter of the plate. This is a no brainer, if the pate is too big then it will never fit in the oven. Way too small and it probably wont turn good. In the majority of cases 1cm diameter less is tolerable.
Step 3. The roller surface diameter. Take a look at the bottom of the microwave plate, the glass is textured but there is a smooth inner ring where the roller sits on. It is important that you purchase a plate that has a roller diameter that matches you oven plate. If it is the wrong size, then it is likely that the roller will spin on the textured surface and wont rotate well if at all.
Step 4. The coupling in the center. Some plate have a shape cast in the center of the plate. This shape mates with the turntable motor to make the plate spin. Not all plate have a coupling, some plates are driven directly by the roller, i.e sharp carousels.
