Whenever I open my fridge door, the light will illuminate with the same frequency of what appears to be a relay in the circuit located in the back. I've isolated the circuit, and my question is, is this a bad relay or a mystery circuit component that needs to be swapped out. I've surveyed the board and I see a brown around a resistor-- could this be the issue. (if I can figure out how to post a picture, I will shortly)

Thanks!
