Samsung fridge reset, display vs full power cycle?

[Thomas Martinez]

See, I saw a couple of posts about resetting Samsung fridges so I thought I’d open this up for discussion as there seems to be some confusion about the methods.
The first method is for those who has issues with the display and panel of the Samsung fridge. All you have to do is hold down the Power Freeze, Power Cool buttons at the same time for about 5 to 10 second. This will fix most issue with the display panel.
The other method is for people with actual fridge issues. For this one, unplug the fridge from the wall, press any button on the fridge panel to discharge the capacitors, then plug the fridge back in the wall. This will allow the fridge to undergo a hard reset and will fix most of the actual problems with the fridge’s operation.
I would say the panel reset is for cosmetic only.

panel reset is honestly 90% cosmetic in my experience. If the compressor isnt kicking in or you've got an actual sensor fault that button combo aint doing anything for you

The step to discharge is real and people just dont understand why unplugging the fridge isnt working. The control boards can hold a charge for 30+ seconds. The relays dont drop out completely so the MCU doesn't get a cold boot when unplugged. Pressing a button while unplugged will properly discharge the board. Same logic to plugging in the laptop battery.

why does pressing a button actualy discharge the caps tho? like is it just closing a circuit to bleed them or is there something specific the firmware does on shutdown

It’s just closing a circuit. The button doesn’t do anything smart because there’s no power to the fridge firmware. It’s just a path for the capacitors to drain through the load of the button that’s being pressed.

samsung fridges are garbage just buy an LG

Worked on these for 8 years as an appliance tech and the button combo is basically useless. Any actual fridge issues, fault codes, ice maker won’t make ice, fridge fan doesn’t spin, fridge won’t maintain temp, none of these will go away with the button combo. The panel will reset for ~12 hour then the issue will come up again. The full power cycle gives the fridge a chance to read the temperature sensors which sometimes resets the fault condition. Neither of these methods will fix your fridge, especially since if they do, it will happen again within the week.

mine was flashing 22E for weeks, tried the button combo, unplugged for 5 mins nothing, ended up being the defrost sensor. The resets are placebo for half the time

how long do you guys typically leave it unplugged for? ive seen people say 30 seconds and others say 10 minutes

5 min is plenty if you do the button press discharge. If you dont do the button press the caps could still have something in them after an hour

the button combo stopped working on my model (RF28) with the latest firmware update. Used to work but now its just power cool and power freeze separately

i just flip the breaker to reset it. Much easier than trying to pull the fridge out

Flipping the breaker will leave the charge in the board’s caps. Same problem but you moved where you cut the power. You have to press a button on the control panel to bleed the caps.

huh okay thanks for the info. I didnt know that

have any of you measured how long the caps hold the charge? Curious to know if its 30 seconds or a couple minutes.
