How to Replace a Thermostat in a Fridge?

If there cooling and defrosting problem in your fridge. Also over cooling or not getting cooling properly problem. Then the problem relates to thermostat.
The procedure to replace the thermostat is as follows: ---
1) First of all unplug the fridge/refrigerator unit from electrical outlet for complete safety.
2) In top freezer and bottom refrigerator model units. The thermostat is located at the rear of freezer side. But in some units its located in the bottom of the refrigerator floor panel.
3) In side-by-side refrigerator the thermostat is located at the back of the freezer side.
4) To remove the thermostat you will have to remove the screws from the icemaker section located in the freezer section.
5) After the screws from the freezer’s inner section are removed. The inside panel will get loose and come out.
6) Many a time the screws are hidden under rubber type butches. So its bit hard to locate the screws. So check out properly that all the screws in the inner section are properly removed.
7) After the inside panel of the freezer section is removed. You will see the thermostat. It has wires connected to its terminals. Be care full that you don’t pull out any wires. They are very thin and delicate wires.
8) The wires are connected to the thermostat by a connector. So slowly remove the connector from the thermostat using a needle nose pier. Take care you don’t put any force while doing this. It’s very delicate but not very hard to do.
9) After the wires are removed. Remove the screws holding the thermostat .In some models the thermostat is screwed to evaporator coil tubes. In that cases take care you don’t damage the tube while removing the screws holding the thermostat.
10) Before removing the thermostat take care you note down the position of old thermostat. so after the old thermostat is removed out by removing the screws. Place the new thermostat in the same exact position.
11) Refit all the parts which you removed while removing the old thermostat in reverse method. Take care you don’t miss any part fitting.
This will help. Thanks.

The freezer is not freezing. Is cold only.


The problem which you mentioned is related to faulty/ weak compressor.--------- I will explain with more detail.------

The working procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located.------------ But as you mentioned that freezer not cooling this indicates problem with compressor.When compressor cools the freezer section then fridge section gets cold.If freezer section is not getting properly cold then fridge section will not cool properly/.So the problem relates to compressor.---------- In the compressor there is a refrigerant called FREON.With the help of this Freon the compressor cools the freezer section.Freon is a gaseous type cooling agent.The compressor will stop cooling when coolant gets leaked from its chamber.--------- Again recharging the Freon is possible, but the cost for that recharging is approx the cost of new compressor.So its always advisable to get compressor replaced.Because new compressor has warranty for few years.------------------ You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

the freezer component is frezzing continuously.


This problem is related to defrost.

Try manual defrost reset procedure: ----

First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. It will take near to 4 hours to get run in its proper cooling cycle. Then check, if the problem returns again. If the same problem occurs then it's defrost problem. The defrost board and the defrost thermostat/heater is not functioning properly and it has to be checked and replaced. you can get the required parts from online sites like:---

www.repairclinic.com or from searspartsdirect online site.---------

If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The procedure of this unit is as follows: --- The compressor starts then it cools the freezer section. When the freezer reaches its cooling level the defrost cycle starts functioning. In this cycle the fan in the freezer section starts running and the cool air in the freezer section is passed to the fridge section and the fridge section gets cold. The air from freezer to refrigerator passes from the section, in that section the damper is located.

NEFF K4663 fridge. the freezer works ok but refrigerator space does not go below 9deg C even at highest setting. have defrosted and water drain is clear.


The defrost board is not functioning properly.;

When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the refrigerator from main power outlet for 4 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

Icing up, not defrosting corretly in freezer. Frig not staying cold enough.


Your refrigerator problem is directly related to your icing up - excess frost / icing up, defrosting problems causes cooling problems.
To rule out other problems shut down your unit and MANUALLy defrost it using a blowdryer, get all that ice buildup melted as well as the evap coils in your freezer - once it is fully defrosted put back the panel and turn on - give it a couple of hours to cool - if it cools properly, it is a defrost problem. Hopefully too, this resets your controlboard.

If problem returns eventually, you have a defrost timer problem and will need to get it checked - it can be any of the defrost components, controlboard, defrost thermostat, etc.
