Time for a new cold control. That thermostat kills the power to everything, Their are only 2 wires and a ground. Pretty simple to swap out.

most likely you have a defrost problem seeing how your freezer is on top heres what to do go into your freezer and remove the rear panel of the freezer then assure that there is no ice build up on the inside of the freezer if there is then use a hair dryer to defrost the ice this is only a temporary fix if you were not to proceed within 4 weeks you would have the same problem once again under the condensor is a small drain make sure that this drain is free from ice as well Here is what's happening when you have a malfunction in the defrost system.
  • Air cannot circulate from the freezer(where the cold happens basically) to the fresh food section.
  • Your refrigerator will run constantly to try to cool the fresh food section. This will develop a new set of problems with your refrigerator. More on that later....
  • Excess frost builds up within the coils inside the freezer. This is what is blocking the air flow to the fresh food section
  • Usually you will notice the icemaker will stop making ice. Poor air flow and not quite cold enough temperatures in the freezer cause this
  • Water will not come through the dispenser on the door. Cold air settles, the water resovoir will freeze.
  • Compressor may overheat and shut off. This is when you hear, click, click, click. Not good
  • Ice Cream in the Freezer will start to get soft. That's really not that bad. lol
What can you do about this. Let me explain the defrost system in general so you get an understanding of what is going on.
The coils inside the freezer are the only part inside the whole refrigerator that "get cold". They need to stay free from excess frost build up so that air can pass through the coils and reach the refrigerator section of your refrigerator. Every eight hours or so, depending on the type of defrost timer or control you have, the compressor and fans will shut off and the machine will go into defrost mode. When the refrigerator is in defrost there is a heater that is tied into the evaporator coils inside the freezer that comes on. This heater is behind the rear panel inside the freezer where the evaporator coils are located. It melts the frost that has accumulated over the course of time. After about thirty minutes the machine comes out of defrost and goes back to normal operation.
Now the air can continue to pass through the coils and keep the freezer frozen and the refrigerator cool and everybody is happy.what you have to do is do a continuity test on the defrost thermostat as well as the defrost heater and assure that the fan is working as well the continuity test is done with the power unplugged in the machine heres what these parts do Defrost Thermostat
This is the component that controls how long the heater stays on when the machine is in defrost mode. Say the defrost cycle is thirty minutes, the heater may only be on for ten of those thirty minutes on the timer controls. On Adaptive Defrost Controls, when the heater shuts off, shortly after the machine exits defrost mode. Basically if the heater only stays on for ten minutes, the whole defrost cycle will only be about 12 or 13 minutes long
Basically when the heater comes on, it starts to melt the frost on the evaporator. Once all the ice and frost is gone, the temperature behind the panel will start to rise. Once the temperature behind the panel rises to a certain temperature, the thermostat will break the current of electricity going to the heater. Bam, it shuts off and prevents your freezer from becoming a sauna, or an oven. I'm sure you get the drift. The heater is on the bottom of the evaporator coils and the defrost thermostat sits on top of the evaporator coils.
Defrost Heater
This is the last component in the defrost system. This one should be pretty simple. By now if you have read this far you should already know what this does and how important is it. Some defrost heaters are a coil of wire in a glass tube under the evaporator coils. Works like a light bulb basically. The other style looks like the bake element in your stove. They both get red hot either way and melt the frost.
Defrost control or timer.refrigerator-defrost-timers.jpg Some refrigerators have a defrost timer. This type works like a clock. Every eight hours or so the machine hits the defrost spot and that's when defrost occurs

Some refrigerators have an Adaptive Defrost Control. This is what makes a refrigerator energy efficient. It varys the length of time it takes the machine to go into defrost. So instead of the energy hogging heater 240545401adc-board.jpgcoming on every eight hours, it may be 24 hours, 18 hours, 10.5 hours, who knows. It depends on how many times you have opened the doors, how long the compressor has run. This is good because the refrigerator may not need to go into defrost every eight hours. Now you are saving energy check the tstat and the heater and assure that the fan is working properly and message me back if you have any further questions and please remember when this chat has concluded to rank how this opinion has helped Thanks Again Rick

DEFROST PROBLEM
The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can't flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won't turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it's bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it's in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

Look at the cover where the temp control knob is. Underneath there will be a hole about 3/8" dia inside will be a slot head screw. Turn this screw with a screwdriver. It will make a ratcheting sound as it rotates then a click when it goes into defrost mode. Leave it there and it should continue cycling on it's own.
