Samsung Refrigerator - RF34H9960: Fridge keeps turning off and back on every few minutes.

Thu, 21 Dec 2023 15:56:54 -0700

We have a Samsung French 4-door chef collection with flex area Model:RF34H9960S4/AA-0000. It randomly just started turning off and then turns right back on but cycles through this every couple of minutes. Can't keep anything in it because it is not holding temp with the constant turning off and back on. Any one with any ideas? We just can not afford $250 + for a repair service since it is out of warranty. Thanks+

Sorry just now seeing this!

Here is a photo of what we get when we try to run diagnostics. Thanks!

Samsung Refrigerator - RF34H9960: Lightning hit my house and now my refrigerator flashing Error Code C66

Samsung Refrigerator RF34H9960 Touchpad not responding. Error C 66 Flashing and all normal cooling. Ice machine works and water also works. All light works. Touchpad wouldn’t respond. Also bought brand right bottom touchpad and still flashing Error Code C 66. I tried unplugging the refrigerator and waited for a week to make sure the error code would reset but still flushing error code C 66.

Hi,

I bought brand oem Samsung chef Refrigerator Rev. 08

MODEL CODE : RF34H9960S4/AA mainboard and replaced with the newer one and error C66 is still flashing. The touchscreen still wouldn’t respond.

Tried to press all buttons and non responsive.

I also replaced the freezer right side touchscreen with newer oem parts and still no . Ice machine works, the backing fan works fine and ice buildup.

THANK FOR ANY HELP.

Freezer wont cool lower than 32 even set to -8. Could this be a thermistor issue? It seems consistent at 32.

Samsung Refrigerator - RF34H9960: Why is my refrigerator display beeping and blinking?

Mon, 18 Dec 2023 11:30:07 -0700

Hi All,

I'm having a problem with my Samsung Chef Collection Refrigerator (RF34H9960S4AA), which

When I select a type of ice on the outer control panel (top left door), it will begin to beep and the display with flash after a few seconds. This has nothing to do with the inner temperature (which remains at 37 degrees F) as the beeping happens even with the door closed.

Also, when I try to reset the filter (bottom right door, inner control panel) a ER PC shows up on my screen. I've researched this online and spoken to Samsung support and they linked me to a picture of the user guide, which shows to disconnect a wire above the upper left door on the panel, however the picture does not look at all similar to the panel I've encountered, and there are numerous wire harnesses inside the panel, so not sure which (if any) to disconnect and reconnect.

Does anyone know why this might be happening?

Thanks very much!

RF34H9950S4 right freezer door panel not lighting up so the freezer temperature cannot be adjusted to freeze so only cools like a fridge.
