Samsung microwave reset, is the unplug method actually a thing?

Seen in a few different threads regarding various appliances, so figured I'd ask the question here of the community regarding whether or not the Samsung microwoves actualy even have a reset procedure.
From what I understand about them, there is no reset button on the appliance. Instead, to "reset" the door, one is supposed to simply unplug the Samsung microwave for 5-10 minutes, then plug it back in, and reset the clock on the appliance. The theory behind this is that by unplugging it for 5-10 minutes, the capacitor on the control board will fully drain, essentially "resetting" the appliance. My question is: does the 5-10 minute wait really do anything besides show off how much they knows about electronics? Isnt 30 second enough to fully drain the capacitors on these appliances?
Curious to know from those with more experience what the consensus are on this issue! Is there some button combination on certain models of Samsung microwaves to perform a "factory reset"? Is this the only procedure available for these appliances?

The unplug method is real, 30 seconds is usually enough tbh. The 5-10 min thing is overkill, caps drain way faster than that on these boards.
 
I've been fixing samsungs for about 12 years and the dirty truth is the unplug fix is a coin flip. If the panel freeze up due to a voltage spike or something weird on the MCU it will clear up. If the panel is freezing every other week, the membrane or control board are on it's way out. Had one last month that the customer was doing this every other week for the past 6 month. Board was cooked when I opened it up, traces discolored near the relay.
 
wait so does the clock setting thing actualy matter or is that just a side effect? like is there any model where you HAVE to reset the clock for it to fully boot back up?

30 seconds my ass. Ive seen boards hold state for several minutes on these, especially the ones with the bigger filter caps on the low voltage rail. 5 min is the safe bet.

nah youre thinking of older units. Moddern samsung boards bleed off in under a minute, ive metered them. Unless you got proof otherwise stop spreading 5 min as gospel.
 
mine locks up like once every few months and the unplug always fixes it, never waited more than maybe 2 minutes. Been doing this for 4 year on the same unit so its not always a sign of impending doom
 
samsung appliances are garbage anyway. Wouldnt waste my time troubleshooting one, just buy a panasonic and be done with it.
 
there's no button combination to do a factory reset on the consumer models of samsung microwaves. The service techs get to use a diagnostic mode on some of the over the range models but only for relays and sensors. The unplug method is the only one available to the end user and it's by design.
 
basically yes. The same as cold booting any other device with a microcontroller on it. The 5-10 min reset is just some crap that was copied and pasted into every single appliance forum by somebody that had one appliance take a while to clear up after being unplugged. If it takes 2 minutes to clear up it's never going to clear up in 10 minutes. Ive serviced about 200 of these Samsung microwaves and the unplug method works about 60% of the time and the other 40% the panel will freeze up again in just a few weeks. In most cases it's either the door switch acting up mimicing the control panel lock up, not a control board issue. Definately worth checking that switch before you jump to the control board.

okay so door switch acting up mimicing the panel lock up is interesting, how would you tell the difference between the two from outside of the microwave?
