I did it with a dremel and some engineering. we cleaned out a spot in the spray foam the was along the side wall of the deep well of the fridge and the step. attached it will aluminum tape and then used foodstuff spray foam to re-fill the area. once the foam dried we cut and leveled it and resealed the opening with aluminum tape. been working fine since.
