I had the same problem with the freezer light and figured out an easy fix for ours. Our model is RF261BEAESR (french doors, freezer door on the bottom). I read that LED lights last pretty long, so if the bulb is LED (I’m not sure but I assume it is), then it’s not likely the bulb. I saw a YouTube video about how to replace the switch, which is a different location in the freezer from where the bulb is. Here’s the video:
Replacing the switch looks like a lot of work! We didn’t think we needed to replace the switch, because the light has worked intermittently. We had other problems with the drawer sticking very badly. Using a hair dryer and lubricating the rails helped the drawer sticking problem. It turned out that the switch was sticking as well. I used a hair dryer (the space is tight to get to the switch, so I used a small plate to direct the air to the switch). That got it unstuck and the light is working again. This was done without removing the racks or door as shown in the above video, so it was really an easy fix. I may also try adding some lubricant if it sticks again.
