Hoping someone on here can help. I've got a 2009 Frigidaire which has been running non stop all day.The Fridge section is about 35 degrees Farenhight, while the freezer varies between 5 above and 5 below. The thermostat dial in the freezer section is set all the way to the left, warmest possible setting. The fridge is most of the way to the left. The settings have not been changed since it was new, almost 4 years ago. It worked properly until this week.I pulled the unit out from the wall, hoping to vacuum the coils as we did with our old model. No coils back there. None up front either. There's a cardboard panel in back, down low at floor level, but this appears to be something to do with an ice maker, which we didn't get. Pulled up one corner of this and it seemed pretty clean under there, but vacuumed all around behind the unit and under the front. No change. Also checked for obvious air leaks around the doors, with no luck. Not really sure what else to check. Also not sure if it's safe to leave the unit running when I go to work tomorrow; I don't want to throw out $300 worth of food but worse would be the thing overheats and starts a fire. Any ideas or suggestions on what to do next?Our old fridge was a 1960 Frigidaire which gave us nearly 50 years of reliable service before wearing out. I realize we can't have 1960 style reliability anymore but is this really the beginning of the end for this fridge? Will it be one repair after another from this point on? I've heard all sorts of horror stories from friends/relatives about nearly new appliances self destructing at the five year mark. Should I cut my losses at this point? And are there any other brands that might last a bit longer? Much thanks in advance for any help.-Mike

My thanks for the response. I took the panel off, it was prtty clean back there but vacuumed it as best as I could. The condenser fan was running fine. Also made sure there was plenty of airflow around the unit and left it away from the wall a bit more than before. There's nothing inside blocking the cold air jets, it's only half full in there so stuffs not crammed against the back. It's been brutally hot here this week and there's no a/c except in the beedroom, but we've had heat waves before without any problems from the fridge. Everythings "nomal" when you look inside, no frost build-up, no funny noises or smells. It just won't shut off. I'm at a loss about what to try next. Much thanks for any help.

My thanks again for the response. Just got home from work and sure enough it was roaring away. Freezer at -5 degrees F, fridge at about 30. I turned the cold control to off and it shut off. Turned it back on, it stayed off about a minute and right back to running again. I'm told however that it did shut off twice in the early morning, for about a half hour each time. Maybe because it was cooler in the house? But we've had heat waves before that haven't affected the fridge. I've set the cold control to a warmer setting but it was generally right at 35-40 degrees F at the old setting. Not really sure what to do next, but will keep an eye on it to see if it might shut off at the warmer setting. My sincere thanks for any help. -Mike

You might have an airflow problem, check for ice blocking the air vents.

Remove the back freezer panel and check the frost pattern, should be total, light frost.
