The light bulb associated witht the control box at the top of the refrigerator section operates intermittently. This appears to be a symptom of a loose wire or bad socket. Everything else seems to work fine. Changing the light bulb does not eliminate the intermittent operation. How do I remove the control box to access the wiring? Any suggestions or precautions to removing the control box? I have made one attempt to remove the control box but the unit seemed to have a screw that I could not find to release the unit. Thanks for any assistance.:confused:
