Is this spacer the little black rubber thing that keeps the grate from setting right on the actual stove?
Answer Hello May-May! No, the spacer part number 316517600 is the oven door spacer. The manufacturer does not list the grate feet for your model 790.77483806. However, this is a Kenmore manufactured by Frigidaire. Frigidaire has a foot kit you may be able to try on your appliance as part number 5304475129. This kit comes with 8 feet and the adhesive needed to install the grate feet. Thanks!
