Product review (5 stars): Cheapest I've seen, fixed by strobing lights.
We had the strobing lights in fridge and freezer.  I read into and found the top light in the fridge to be the culprit. I read that sometimes just unplugging and replugging the light will correct the issue but it didn't in my case. This was the cheapest I'd seen this light, other sites wanted over 200!!. My wife is happy and the fridge works great again. Just YouTube how to remove the light if your not sure.
