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.
