A Sub Zero refrigerator was experiencing inconsistent interior lighting. Upon inspection, I identified a faulty light switch as the root cause. The switch was exhibiting signs of wear and tear, which led to the intermittent lighting issues. I replaced the defective switch with a new one, ensuring it was properly installed and functioning. After the replacement, the interior lighting operated consistently, resolving the problem. The refrigerator now provides reliable lighting, enhancing usability and convenience for the user.
