my fridge has just decided to stop working! instead of cold it is normal air, my husband wants to throw it away and buy a new one but i dont think that the problem could be that serious.
It was working last night when we went to bed but this morning we have warm cheese and lumpy milk.
Any suggestions as to what we should check or do? so far we have checked the temp button. the freezer is still working.

Re: no cold fridge
Open the freezer and listen for the evaporator fan. You may have to hold the door switch closed for it to come on. If you dont hear the fan running then you probably need a fan motor or or defrost bimetal depending on the make and model.
If the fan is working, look at the back wall of the freezer. If you see a thick coat of frost, you probably have a problem with the defrost system.
Also, check to make sure refrigerator light is shutting off when you close the door. A 40 watt bulb will curdle a gallon of milk quickly.
Of course, you also want to rule out any possibility that the fridge door was left slightly open over night before you decide to toss it.

Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for.
Check on the cold control if faulty, replace the cold control, not having found any other problem, do check on plastic air deflector at the top rear of the frig had been knocked off. replaced it if faulty. As you know, the deflector directs the freezer air toward the front of the frig and the rear of the cold control, which is now functioning properly. Good luck.......
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp. The problem could be the electronic control if you have one or the mechanical linkages.
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

fridge temp .. I don't know what he was doing with the putty unless he was stopping up the vent which won't work because you have to have the air circulation for the fridge section to work. The fridge temp control may be the problem.
Generally on these models they rely on cold air being pumped fr\om the freezer to the fridge and have a adjusting device to control the flow, you need to locate and check this is free and working properly. Another reason for freezer ice up is a shortage of gas in the unit, this is usually unfixable as the leak can rarely be found as it usually occurs within the cabinet case. Sorry to say it would then be a throw away.
That could be a fairly benign contact problem.
If you own a simple multimeter with a continuity (sometimes marked with a diode symbol) or Ohms function, you can attach the probes to the AC plug prongs one probe to each) and thump away at the fridge (maybe opening the lower panel and poking too) to see if you can isolate the source of the problem.
It really sounds like the appliance is still ready to go but that some electrical connection isn't one anymore.
