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.

Demo mode is built into the electronics for dealers. This allows the dealer to show potential customers all of the functions of the refrigerator on the floor with the exception of “Cooling Mode” this helps with energy consumption.

On Samsung refrigerators that don’t have a display, the lights will be scrolling up and down. This means the same thing. The refrigerator is in Demo/Floor model mode.

To get the refrigerator out of demo you need to press several buttons. This button sequence is the same for display and non display mode. The only exception is for models that use the WiFi touchscreen.

Press the top left button and the one directly below it at the same time and hold in for 3-5 seconds. This will get rid of the OF OF or scrolling display and send the refrigerator directly back into “cooling mode”

Have a Samsung refrigerator error code? Then this article is for you. Below is how to fix the dreaded refrigerator error code.

This is a fairly new error code on Samsung refrigerators. I have only seen a few of these refrigerators display this error code. The schematic and tech sheet actually do not list this error code.

I have only seen this error on french door double freezer drawer Samsung refrigerators.

The 84 E stands for a locked rotor. There is a small control board on the back of the refrigerator it’s called an inverter control board. Since Samsung uses a DC three speed compressor they use an inverter board to change the voltage to the compressor. When the rotor locks up the amp draw goes way up and the inverter control board senses this and will throw the error code 84 E on the front of the digital display.

This is actually a very bad error code on these refrigerators. It means the rotor is locked up inside the compressor and the only way to solve this issue is to actually replace the compressor. Unfortunately this means a basic rebuild of the sealed system of the refrigerator. It’s a pretty big job to do this. You not only need special tools you also need a special license to recover the freon from the refrigerators sealed system.

I have however been able to solve this problem twice out of the 7 or 8 times I’ve seen this error by simply replacing the inverter control board on the back of the unit by the compressor.  The inverter board on the back is usually flashing four times which means again locked rotor.

Fortunately for every one of these that I’ve seen they have been covered under first year warranty. Now I know that doesn’t say a lot for Samsung but remember no matter which brand appliance you buy it will have issues eventually. Things just aren’t made like they used to be. I hear it everyday my old refrigerator lasted 2o years.. You’ll never buy another one that last that long..
