I have a GE Monogram built in which has had continual icing problems. I ordered a new drain pan heater and drain pan foam insulation (part numbers WR51X321 and WR17X3037) because in all my fiddling they both got kind of screwed up. I recently learned that GE has a $300 icing repair kit (WR49X10021). I'd like to know what this kit contains and what is involved in installing it especially since I have never been able to remove the grill immediately above the doors (pictured below).
