Hi, As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...
Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...
If the freezer is staying cold it sounds like a defrost system problem. A bad timer, heater or thermostat can cause frost to build up on the coils and block air flow to the refrig side. Check out ACMEHowTo.com for troubleshooting the defroster problem.
There is a small duct between the freezer and refrigerator side if this is blocked the frig side won't cool.

1.If this is only a fridge the one knob will be for the min and the other for the max. max. : As soon as you switch the fridge on it will cool down the fridge to max cool down temp. example -2deg. min. : As soon as the fridge reaches the max cool down temp and it had switch the compressor off, the fridge will start to warm up slowly, by the time it reaches the min allowed warming up temp, it will switch the compressor back on and do the cycle all over again. 2. If it is a fridge/freezer setup, the one knob will be for the fidge and the other for the freezer. If the temp in the freezer is fine a fan is activated and blows all the cool air to the fridge and controls the temp. by activating the fan.
You have ice on the temp control door that has blocked air flow. You will need to pull off the back inside panel of the freezer and de-ice it or have a tech do it and test the defrost controller. That is most likely the reason for the freeze up in the first place. Hope this helps. Good luck.
What happens is the defrost is controlled electronically from a circuit board, when this goes bad, the freezer quits defrosting, and freezes the fans that circulate air through the fridge side of things.
To check this, unplug the entire fridge, leave the freezer open, wait for it to defrost a bit, if this causes the fridge to start cooling again when you plug it back in, then its the defrost. You should also see ice crystals on the back of the freezer just under the icemaker.
I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........
In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.
Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.
Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)
Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.
Unless specifically made for use in a garage most units won't work properly. The owners manual should say what the temp range for proper operation is (usually 55F is the low range). This is because the refrigerator section doesn't need to be "cooling" to maintain 37F if the temps on the outside are below 55F. These things are made to work in a 70F room and will not work properly if under 55F. Stupid thing thinks it's cold enough so it will never turn on, the refer section will stay cold/cool due to outside temps but since the compressor never runs the freezer will just be the same temp as the refer section (at best). Sorry, but in order for a freezer or refrigerator to work in an unheated space it must have the temp control device controling the freezer section NOT the fresh food section. In other words, that model will not work in a garage unless the temps are above 55F always.
