    This helped me alot by identifying that the fans voltage is 12V DC. Checking the voltage with the fan plugged in can be misleading. Mine showed no voltage this way, indicating that the PCB may have been bad, but after taking the fan out and putting 12 volts to it, it would not run! The fan was definitely bad. The PCB stops sending voltage to the fan after it repeatedly gets no response from the fan which can make you think the PCB is bad when it is not. It's a good idea to bench test the fan.

      Watch the video again. He said the voltage to the fans was 8 or 11 VDC. Also you can check the fan motor by checking the continuity between the red and black wires on the fan itself. Continuity good fan motor. open bad motor. He said white wire sends fan speed info back to the PCB.

    • @reid7085

      Yes, but I was getting no voltage while the fan was plugged in to the fridge & the fridge compressor was running, magnets on the reed switches. The PCB had already cut off power to the fan. So I tested the freezer's evap fan with a battery & it worked, the refrigerator evap fan didn't.

    Great video! I have a different model Samsung RS25H5111, but the circuitry seems the same. My problem is a little bit different. The fan turns freely and there is no ice around it. However, sometimes the fan works either at full speed and sometimes it doesn't work at all even on Power cool. It doesn't matter what temperature the refrigerator is at. Everything seems okay, including the power freeze on the freezer side, but is inconsistent on the refrig side. I ran the full self diagnostic check and there are no error codes picked up. Wiring between the evaporator fan socket to the mother board shows good continuity. The refrigerator can go for a day or more without the fan working and then all of a sudden it starts to work. Would this be a mother board problem or some other sensor causing the mother board not to supply the voltage to the fan?

      Same here. Not certain about the continuity though. The voltage seems to fluctuate and the slightest movement in the wires either turns the fan off or on again. Would love to know if either of you found something out.

    My refrigerator makes 5 attempts to start the fan motor and then disables it. I measured the voltage on the fan (while it was making start attempts) it was correct 11.3V, I even got a replacement fan which behaves the same way. Looks like the control board can't get a feedback from the fan that it's spinning...Bad control board?

    Dear Parts Dr, your video was helpful to see if the fan went on with the lights off. Can you tell me for the samsung RF197ACPN with the french door and freezer door on the bottom, where to turn off the light on the bottom drawer. I used the two magnets on the top doors and it works. But I cannot find anything on the manuals about the light sensor switch on the bottom drawer. Your help would be appreciated.

      @@PartsDr Thanks for the reply. I have a Samsung inverter refrigerator (freezer top). It works fine until around 7 hours and then stops working. If I unplug and plug it right away, it wont turn on. After some hours, it will turn on. It has high temperature fluctuation. If I set the freezer to -21C, it will even cool down to -32C. The Samsung official service came and said my evaporator is having a small hole. I didnt accept. Then 3 more technicians came. One said the defrost system is problematic and changed the sensors without measuring the resistors. Then another one came and said the invertor motor should be replaced. Then another one came, took the inverter board and returned and then he said, it is hard to find the cause, buy a new Ref! Since then, I am trying the repair it without experience. I just am an electronic engineer and understand something from the board; however, I do not even have the board map!

    Great tips. Can you help me figure out my issue please? Freezer cold, main fridge not- running about 50F (this same unit in this video- Samsung RF24xxx). The voltage to fan is perfect. With magnets on, I observed that the main fridge fan is "running." Could it be running too slow- anyway to check that (fan speed?) The defrost temp. Sensor checked out fine- the ohm values perfectly match those on the Samsung chart. I tested at room temp., 70F and ~33F (ice water.) The coils in the back were just cleaned and no interior vents are blocked.
    At this point, should I change the fan and cover assembly just in case the fan is old and running slow? The fridge is 7 years old. The evaporator in the main fridge has been consistently icing but I manually defrosted it, completely cleared the drain / tubes and I think it's better now but it haven't been too long to know for sure. In FD mode (Forced Defrost), I put ice near the sensor, I read a temp of the heater element to ~300F near the bottom yet the top of the coil was relatively cool 70F's. The coil is however completely clear of ice and draining fine, yet inside the fridge is about 50F. WHAT CAN I TRY NEXT TO SOLVE THIS ISSUE PLEASE?

    My fan functions at the onset but stops running after around 24 hours from when the fridge was plugged. If the control board disables fan for ten minutes, I suppose there won't be any power when tested. Will there always be power in the main control board? I'm trying to figure out if the board or fan that needs replacing (maybe it runs low after 24 hours so the board switches off the power, is that possible?).

    any thoughts as to why my rs265tdrs/xaa leaks water on the floor at the front of the fridge side, about once a day? the water seems to come from under the fridge, not from inside of it. the evaporator tray underneath seems to fill evenly but the water isn't evaporating fast enough. it used to leak water from inside the freezer, which would also freeze in the bottom of the freezer, but it did that for months - but the freezer stopped working. so i emptied the whole thing, defrosted everything, did your various diagnostics, and while it all checks out, the fridge side now leaks water. the freezer still isn't freezing.
    i get no error codes. oh and i also replaced the power supply board and the main control board. there used to be a smell of over-heated electronic components coming from the control and power board cavity in the back, but after changing those boards, the odor is gone... what am i missing?
