I ordered the insulation kit for the range. Completely dismantled the range. Had to remove the remaining insulation. Then removed all evidence of the mice infestation. Scrubbed and deodorized the oven shell, covered all holes and entry places in the back and bottom with stainless steel screen. So not to interfere with air flow (this is a self cleaning range and gets very hot when cleaning.) Reassembled range, checked for gas leaks, and operation of all burners also oven operation. This would be a little complicated for some people but I was once an appliance repair technician. This was like the old days!
