None of the interior lights worked on my fridge (1 1/2 year old Kenmore Elite) & I had a ER CO fault on my display. I couldn't get at the power plug, so i just tripped the breaker for about 15 secs and then closed it. To my surprise, the lights came back on and the fault code disappeared. Everything looks OK for now. Anyway..........i reset my fault.........simply by powering down and powering back up
