Its the problem of the mother board and defrost heater.but before replacing it give a last try by checking this.

In your fridge there is what is called an encoder.

It is number 424 in the fresh food section.

There is one other thing that can effect the defrost and that is the defrost thermostat.

It is number 240 in the freezer section.

As the air that is circulated by the fan inside the freezer passes through the fins of the freezer coils, moisture in the air turns to frost and deposits on the fin surfaces of the freezer coils. If this frost was allowed to accumulate, eventually it would build up to a point where the air would no longer circulate. All refrigerators need to be defrosted some way if the defrost assembly is working so in that case the assembly is not working may be if you defrost it manually the fridge will start working and it will build up again so you have to
replace the automatic defrost assembly . defrost the coils. The defroster assembly is two glass tubes with springs in them connected by wires.

You must check the electronic relay connecting into that switch, or you have an option to attached a digital defrost timer device.

    Most modern refrigerators defrost
    automatically. They have a defrost timer, a defrost heater, and a
    defrost terminator. When a frost-free refrigerator is running, it
    builds up frost on the tubing in the back of the freezer wall.


















    it essentially heats up coils to
    melt the ice. If it isn't working right, ice remains on the tubing and,
    eventually, restricts airflow through the refrigerator.




    On
    some refrigerators, you can manually advance the defrost timer, a small
    black box that may be located almost anywhere but is usually on the
    ceiling of the fresh food section. Advance it until it clicks into the
    defrost mode (you should be able to hear the heaters come on).

    If
    this works, the defrost timer is defective and will need to be
    replaced, but this action will keep it running for a little while. If
    this technique doesn't work, the problem is probably the heater or the
    terminator. Call the manufacturer for advice.

    At the back of the fridge their is a small black gas cylinder.
    When the gas starts to wear out, the fridge will stop defrosting

    Youll need to have it looked by a proffessional and have the gas refilled

It doesn't defrost
  1. Defrost control board
If the defrost function is not working on your refrigerator it could be an issue with the defrost control board. This control board oversees several internal conditions and regulates the activation of the defrost cycle. A faulty board can be the primary reason your refrigeration unit is not transitioning to the defrost cycle. Over time, the buildup of ice on the evaporator coil will prevent the refrigerator and freezer from maintaining proper internal temperature. It is advisable to first check the defrost heater and the defrost thermostat for continuity prior to replacing the defrost control board.
  1. Main control board
A possible cause for a refrigerator not defrosting, especially on more modern units, is the main control board. The main control board acts as a "brain" for the unit controlling the defrost cycle, compressor, and run time, and essentially acts in place of the defrost timer. The control board can be tested using an ohm meter for functionality and will need to be replaced if bad.
  1. Defrost timer
If the refrigerator is not defrosting the timer could be malfunctioning. Numerous times throughout the day the defrost timer should cycle the defrost heater on as a means to melt frost buildup on the evaporator coils in the freezer. If this timer does not cycle on, then it may be faulty and require replacement.
  1. Defrost heater assembly
If your refrigerator is not defrosting accurately this could be an indication that your defrost heater assembly has failed. This could cause the frost to accrue on the evaporator coils, eventually blocking the airflow resulting in the unit not cooling properly. The defrost heater assembly can be monitored for continuity using an ohm meter and will need to replaced if there is none present.
  1. Defrost thermostat
Another cause of your refrigerator not defrosting is a faulty defrost thermostat. A requirement for the defrost heater to activate to melt away frost on the evaporator coils is a functional defrost thermostat. The defrost thermostat senses the temperature of the evaporator coils and initiates the thawing process by activating the defrost heater. If the thermostat is faulty, it will not sense the lowering temperature of the coils and will not turn on the heater, resulting in an advanced frost build-up. The defrost thermostat can be checked for continuity by using an ohm meter; if there is no continuity the damaged part will need to be replaced.
  1. Defrost sensor with fuse
Another possible cause of a refrigerator that does not defrost properly is a defrost sensor with a fuse. If the defrost sensor fails, the fuse acts as a one-time-only fail safe for the sensor -- if the sensor does not shut off the defrost heater, the fuse will blow when the set temperature is reached. This safety precaution is to keep excessive harm from your unit by the heater and is a one-time use, resulting in the replacement of the entire defrost sensor.
Defrost drain problems
  1. Clogged or freezing defrost drain
If you are experiencing defrost drain issues, it is possibly due to a clogged or freezing drain that is blocking water flow to the bottom of the freezer. This will cause the defrost water to drain and drip down to the bottom of the freezer section. To correct this issue, thaw any ice or remove debris that could be causing the clogged drain or replace the drain heater.
  1. Drain heater
If you are experiencing defrost drain problems, inspect the defrost drain heater. A dislocated or burnt out drain heater will result in the drain tube freezing over. Attempt to return the part to the designated position or replace the damaged part to correct the issue. Search Over 2 1 Million Appliance Parts

Ice forming on bottom of freezer compartment Samsung RF4287HARS.


dont worry about it, you probably didnt get the freezer drawer closed all the way. frost will form when it doesnt get closed properly. just make sure it is closed now and the unit will clear the frost in a few days thru normal defrosting cycles. be sure that the drawer is closing on all sides by looking at the gasket and all should be ok in the future.

Freezer works but fridge does not


Lets see if the defrost timer being turned clockwise slowly will force defrost and cause things to get colder. On page 5 of the (click HERE=>ET4WSKXKQ02 Parts Manual ) you will see location 4? That is the 2188371 Defrost Timer

inside the fresh food com[partment at the top and behind the control panel will be the 2188371 Defrost Timer If forcing defrost solves the cooling problem then just replace the 2188371 Defrost Timer and if not we will need to check the 2176942 Defrost Heater Assembly and the 2192096 Defrost Thermostat Don't buy ba defrost thermostat until we discuss a different way of getting one to work should you need one (last resort because of cost) My focus is defrost timer and defrost heater at this point you will not need all the wires on the defrost thermostat should you need one just splice a simple defrost thermostat into the wiring harness.

Freezer is not defrosting properly , I already change the thermostat, my refigerator model is TBX74UL01 OR TBX74UB01.


If the thermostat is replaced, but still its not defrosting, then two possibilities, either weak defrost heater,Heater is the part which heats and it defrosts, if the heater gets weak, then unit will not defrost properly.And it will take more time to defrost, and till that time, again frost gets collected.---------- But if defrost heater is ok, then problem is defrost board.The defrost board is the part, which controls both thermostat and defrost heater.-----------
This problem is called defrost problem.-------------

So first thing you try is , perform, manual defrost reset procedure.---------

The manual defrost reset procedure is as follows : ----
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. Then check,if same frost is getting collected, then its defrost problem,. 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 defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. IN YOUR case, defrost thermostat is already got replaced, so ignore thermostat, but other two possibilities needs to be checked.----------You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.

Frigidaire PLHS269ZDB9 is not getting cold enough to freeze or make ice. I took off the panel , there is an ice block on the thermostat to the evaporator. trying to defrost.


When the refrigerator is running ( cooling mode ) the defrost timer contacts prevents any power from getting to the defrost heater. When the defrost timer turns off the power to the compressor and fan motor(s) the power is then redirected to the defrost system. The defrost timer motor


Defrost thermostat:
During a defrost cycle, the defrost heater causes the metal alloy in the switch to warm and as it does it curls back and breaks the circuit. As the metal cools, it makes a closed circuit again. A defective thermostat can prevent the defrost heater from coming on or allow it to overheat which could result in heat damage or fire.
The defrost thermostat is located near the defrost heater and is wired in series. It is usually located at the back of a side by side freezer, behind the freezer back wall of a top freezer or under the floor. It will be necessary to remove obstructions such as the contents of the freezer, freezer shelves, icemaker and the inside rear or bottom panel of the freezer. At room temperature the defrost thermostat is an open circuit ( no continuity ) and when cooled down the defrost thermostat closes the circuit ( has full continuity ) to allow the defrost heater to come on.



Defrost timers:
The defrost timer is sometimes found behind the front grill of the refrigerator. It may also be found behind a cover plate inside the refrigerator or freezer, in the temperature control console, or behind the refrigerator near the compressor.
The timer is usually held in place with one or more screws. Remove the screws and gently pull the timer out far enough to disconnect the wiring connector.

Locate the timer switch and turn it clockwise until you hear it click. One click and the refrigerator shuts off = defrost mode, second click the compressor and fans come back on = run/cooling mode.

*Some defrost timers are a constant or continuous run timer, which means when ever the refrigerator is plugged in the defrost timer is powered up and running. Some defrost timers are an accumulative run timer, which means when the refrigerator is off the defrost timer is off and not running, when the refrigerator is running the defrost timer is running. This is also sometimes called a demand defrost. The power for the defrost timer goes through the cold control first on an accumulative defrost system. The timers are often the same but will be wired differently to get the different operations.



Defrost heater:

Test the heating element for continuity using a multimeter. Set the multimeter to the ohms setting X1. Place a probe on each terminal. The multimeter should display a reading somewhere between zero and infinity. Because of the number of different elements we cannot tell what your reading should be, but we can be certain of what it shouldn't be. If the reading is zero or infinity the heating element is definitely bad and should be replaced. Proper power ( careful!! ) to the heating element ( 110-120 volts AC ) and the defrost heater does not come on = bad defrost heater.


glohorsa.gif


Some newer refrigerators have been using an electronic board instead of an mechanical defrost timer. The adaptive defrost control does the same job as the defrost timer ( shuts off the refrigerator cooling items and redirects the power to the defrost heater for the defrosting cycle, then redirects the power to the compressor and fans to come back on when the defrost cycle is over ). This adaptive defrost system is a bit different when testing, normally speaking if the defrost heater and defrost thermostat ohm ok, we replace the adaptive defrost board.
