Does your Samsung refrigerator have a defrost issue? Is the freezer or refrigerator not holding a good temperature?

If either side is having a cooling issue, then you most likely have a defrost problem.

In the event that a Samsung refrigerator has a defrost issue, the temps inside both sections will gradually rise. The frost builds up so thick the fan motor can’t pull air across the coils to cool properly.

Samsung refrigerators go into auto defrost every 8-10 hours. The main control board on the back is what sends power to the defrost heater in the refrigerator and freezer (on dual evaporator systems)

Reasons to put a Samsung refrigerator into forced defrost mode:

1. Thermostat/Sensor test good. 2.5k-89k-4.5vdc

2. Defrost elements test good. (Freezer 58 ohms Refrigerator 103 ohms)

3. Need to test parts on evaporator but can’t because frost is to thick to access.

The defrost heater in the freezer is a (215 watt 120vac) cal rod element.

The defrost heater in the refrigerator is a (140 watt 120vac) cal rod element.

To put a Samsung refrigerator into forced defrost mode you need to press a few button sequences:

-Press both the “Power Freeze” and “Fridge”  buttons at the same time.

-Hold both buttons in until display beeps and goes blank.

-To force fridge defrost element to come on, press “Freezer” button a second time.

-To force defrost on both the refrigerator and freezer sections, press the “freeze” button a third time.

At this point you can make your test from the main PCB on the rear or directly at the components.

To exit this mode simply unplug the refrigerator.

  1. 1.last night following a tech video on Samsung I pressed the Power Cool button simultaneously with the freeze button, two zeroes (0) appeared on the screen on the freezer side and the fridge side. I was able to enter a temp reading on the fridge side of 13degrees C following the video info. Fridge was not possible to adjust. Hence my question in my previous mail. Now then did I altered the setting or did the PCB remained at programmed setting? After that I disconnected unit, reconnected, temperature reading on fridge side stopped blinking and remained at 14degrees C and climbing. Now is at 16deg.
    2.if I want to force defrost explain second step. Do I press Power Freeze a second time or twice? Or do I have to press the freeze button and if yes how many times. 3. How and where do I test in the PCB? what readings am I looking for? What setting in my volt-meter? I don’t want to disassemble w unit energized. Thanks again, you r been helpful. Elvr (Mac)

  2. After I have pushed the blue button in my freezer to get the freezer to defrost, some ice melted and water spilled out of my fridge on to the floor. How do I get the freezer to stop defrosting.

    Thank you,

    • Hi, thank you for taking the time to comment. To get the refrigerator out of defrost, simply unplug the unit for one minute. You could also flip the breaker at the panel and leave it off for one minute if you don’t want to pull the refrigerator out.

    • Hi, are you saying the compressor is running but no frost is on the evaporator behind the back panel inside?


  12. At some point over the winter, my refrigerator started making a very loud noise. The refrigerator is 3 1/2 years old. So I did my research and I found out that my refrigerator was freezing up in the back, I was not defrosting. Six months later it happened again, I defrosted it.… Meaning it took everything out of the frige and when it wasn’t frozen any longer, I took the back internal piece off and let it completely defrost. And I plug it back in and it seemed to work fine. Now month went by and it happened again. Is there something that needs to be replaced on refrigerator?

    • Hi, this usually indicates a faulty defrost component. I’ve seen the thermistor cause this issue as well. It does sound like you need a part. On some of these models they changed the location of the thermistor to fix a similar issue.

  20. I have pressed blue button for defrost of my samsung fridge but it’s not coming out even after defrost… My fridge is not working at all.

  21. I have a Samsung RFG297HDBP Refrigerator, (French doors, ice maker/water dispenser on left door, with a freezer drawer on bottom.
    We had the temperature rise in the freezer long enough to partially thaw our frozen food.
    I cleaned the coils, and interiors, left it off for 4 hours, with a fan blowing warm air into the fridge..
    I am monitoring the freezer’s temperature. It stays at 0/-5F, then rises now and again (defrost mode I guess)
    Now, the ice in the ice maker seems to have thawed enough to stick together.
    I am still uncomfortable with restocking the freezer, not sure If my efforts have cured the original problem.
    Any advise?
