One of the small plasitic/ceramic feet on KitchenAid KEMS306BAL0
part number 4312907 for my convention microwave lower rack broke (built in 1993). As a result, when using the microwave, I now get arcing with the rack resting on the lower pan.
When serching partselect and other parts sites, the lower rack (#30 in the parts diagram) comes up as NLA.
I am looking to replace the 1 foot that is broken.
Any suggestions on what I could use to replace the one foot as the oven is working just fine?
You can try going into a local appliance store and look at the microwaves in there, see if you can find one that looks like it has a set of insulators you can use on yours or at least make work, then note that model number and order the parts from it.
