The fridge has stopped working although the bottom freezer compartment is working. There seems to be no cut out on the freezer now, and the freezer is freezing the items in side solid. The model is a Frigidaire FRC150FF it is only 20 months old

It seems lots of people have the same problem with this appliance....including myself......I took the drawers out of the freezer.....removed the iced up plastic cover which houses the fan assembly.....some water had settled in the bottom and froze, therefore stopping it from turning.....just spin it and it with start up again.....hope it helps ;)

buy a new fridge.

Your problems are exactally the same as mine. I have taken the freezer back panels off and fornd the elements blocked with ice, the upper and lower channels to the fridge are blocked with ice and obviously therefore no0 cold air is going the fridge, I have de-frosted the freezer and put back together and everything works great for 2 weeks when the same thing accurs. My settings for both fridge and freezer are on the lowest possible, but the wife does fill the freezer with too much food! I guess I need an expert in!!

Tom, you pretty much have it all covered. Make sure both the freezer fan and the fan under the fridge are both running and keep your eye on the inside back wall of the freezer compartment fro any signs of frost build up (possible defrost problem).
Good luck!

I removed the freezer drawers removed back panel inside the freezer,and discovered that ice had built up around the vent which cools the fridge compartment once I melted this using a hair dryer put it back together and the fridge compartment works fine.

Sounds as though the compressor has stopped working. It feeds both compartments with control from a printed circuit above the top door.Where all your red lights are ablaze! (This can be replaced by removing the 2 screws and "clicking" out the small panel) Check that the compressor is running at the bottom rear of the fridge/freezer before anything else.

Had a similar problem with my Kenwood Fridge Freezer
If you're mechanically minded you could check if there's an opening and motorised flap (usually behind a cover) at the top of the fridge - Cold air from the freezer enters the fridge through this flap) The Sound you heard could have been the motor trying to open / close this flap. This flap can become frozen in the closed position - so cold air is unable to enter the fridge compartment) My fix was to thaw it with a hairdryer and reassemble. Another fix would be to empty the freezer and open the doors - it might take more than 24 hours but once completely defrosted if the flap is the issue it will have defrosted. Once plugged in again the door will open and cold air will start to flow into the fridge compartment. I had a quote for €195 for a call out / repair
I fixed it myself in an hour - Hope it works for you ...

Most side by side and other models of refrigerator freezer combinations are of one basic design. The freezer section does the cooling for both compartments. The refrigerator section gets it cold air from the freezer compartment. Therefore check for frost on the back wall of the freezer compartment. If frost is present there you have a defrost problem and it is cutting off the air that cools the refrigerator section.

I think this problem may already be resolved in some manor because of the date of post. Posts should expire after an unreasonable time period.

AS A FRIDGE ENGINEER I HAVE COME ACROSS THIS PROBLEM BEFORE IT COULD BE A LOSS OF REFRIGERANT ALTHOUGH THIS WOULD STEADILY WORSEN IN USE,MORE LIKELY THERE IS A BLOCKAGE IN THE SYSTEM STOPPING THE REFRIGERANT REACHING ALL THE PIPEWORK THE CHEAPER FREEZERS USE THE SHELFS AS PART OF THE FREEZING SYSTEM.
THE ONLY SOLUTION IS A COMPRESSOR CHANGE AND REGAS (COSTLY IF NOT COVERED BY WARRANTY/GUARANTEE ETC)

IF FREEZER IS MORE THAN 5 YRS OLD BEST TO SCRAP IT UNFORTUNATELY..
