How to replace Refrigerator Coil Brush. I had a friend watch the video and do the work. There was a problem in that the screws were rusted to the back plate and would not screw off. My friend had to use a drill to drill through them to be able to remove them. He had to go to a hardware store to buy a new set. Once we had the new screws it went fairly quickly. Now our oven works great just in time for baking season. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
