SOURCE: water is in the bottom

That water should be draining out the hole in the evaporation compartment. The defrost drain is stopped up. Remove the service panel and get the junk out the hole and the water from defrost will drain out instead of in the bottom.

If ice is forming in the hole a neat trick to know is to run a wire from the defrost heater down in the hole a hair to keep ice from forming over the drain hole.

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.

Part of your message was missing but I do see that you did not mention the defrost thermostat=> 12001937 Defrost Thermostat
Chec for any loose wire or burned electrical connections and remember that the defrost thermostat is designed to be on while below freezing temperatures and once the temperaytures reach 50 degrees F the contacts in the defrost thermostat open to prevent the freezer from getting stuck in the defrost cycle for too long and also is a safety feature. Test the defrost thermostat with a OHM Meter while freezing..

Possible Causes

Symtoms: Frost or ice on evaporator

1. Defrost thermostat faulty->Check defrost thermostat. Replace if failed.

2. Evaporator fan faulty ->Check fan motor. Replace if failed.

3. Defrost control faulty ->Check control and replace if failed.

4. Defrost heater remains open -> Check defrost heater continuity.Replace if failed.

5. Open wire or connector -> Check wiring and connections. Repair as necessary

6. Refrigerant shortage or restriction -> Refrigerant shortage or restriction. This will look very differen that a totally frosted over evaporator. Click here for what that looks like=> Lack of Freon

The defrost circuit in you freezer has failed that is why you have to defrost the coils. The defrost circuit consists of the heater element, the defrost thermostat and the control module. The control module turns off the compressor and powers up the heating element to melt the ice on the coil, after the coil reaches 40 deg F the thermostat cuts off power to the heater. The heating element and thermostat is mounted to the coil. If you have a multimeter and know how to use one, you can check the thermostat and heater. You can check the heating element with a multimeter to see if it has electrically opened. If it has then you will need to replace it. Check also the thermostat, it should be in series with the heater. It should read close to 0 ohms if it is freezing and read infinite ohms if the temperature is above 40F. If the thermostat and heater check out, the problem might be with the control module.

Hi, I have a 20.9 cf (#ET1CHK/ET1CHM). Water


I HAD THE SAME ISSUE EVERY FEW MONTHS. REMOVE THE BACK COVER IN THE FREEZER, YOU WILL SEE A SILVER TRY WITH MOST LIKELY ICE IN IT. THAW THAT ICE AND THERE IS A DRAIN HOLE IN IT. USING A HAIR DRIER GET THE TUBE TO THAW ALSO. ONCE WATER IS FLOWING TAKE A PIECE OF 12 GAUGE BARE COPPER WIRE AND SLIP IT ABOUT 18" INTO THE HOLE. WRAP THE OTHER SIDE OF THE WIRE AROUND THE WIRE COIL YOU SEE WHICH IS THE DEFROSTER. WHEN IT WARMS IT WILL HEAT THE WIRE ALSO AND KEEP THE DRAIN CLEAR
