Can someone please help determine what part I should replace to fix the random beeping? Specifically the oven light button and the timer button. Everything else seems to be working fine on the oven. Thank you in advance!
Since the oven light and timer are activating randomly, along with the beeping, it sounds like the control is registering button presses even though nobody is touching it. This is sometimes called ghost touching.
The good news is that you can try a few things before spending money on a replacement part.
1. Reset the control. Turn off the range’s circuit breaker for about 5 minutes, then restore power. See if the random beeping returns.
2. Clean and dry the control panel. Grease, moisture, or cleaning residue around the touch buttons can sometimes cause false inputs. Wipe the panel with a lightly dampened cloth, then dry it thoroughly. Avoid spraying cleaner directly onto the controls.
3. Check for heat-related issues. Pay attention to whether the beeping happens more often while cooking or shortly afterward. Heat and moisture can sometimes affect a failing touch panel.
4. Watch the display when it beeps. If the timer starts changing or the oven light turns on without anyone touching the controls, that’s a strong indication that the touch interface is sending unwanted commands.
If the problem continues after these checks, I would lean toward replacing the touch control panel assembly, rather than the main oven control board.
For this model, DG94-01312A is a touch panel assembly worth checking. Be sure to confirm compatibility using the complete model number, including the two-digit version suffix (such as /AA-00 or /AA-01), before ordering.

One other thing worth checking: With the breaker off, inspect the touch panel’s ribbon cable connection for looseness, corrosion, or moisture.
One question: Does the oven beep and activate the light or timer even when it hasn’t been used for several hours, or does this mainly happen during or after cooking?
That will help narrow down whether we’re dealing with a failing touch panel or a heat-related issue.
Thank you so much for the reply! We tried switching off the breaker and cleaning the touch panel. They both didn’t work. It will beep even when the oven has been off for hours.
Thanks for the update! Since you’ve already tried resetting the breaker and cleaning the touch panel, and the range continues to beep even after sitting unused for hours, I’m leaning toward a problem with the touch control panel (user interface).
On your Samsung NE58K9430SS/AA, the touch panel sends commands to the electronic control board. If the panel develops an internal fault, it can act like someone is pressing buttons even when nobody is touching it. That would explain the random beeping, oven light turning on and off, and timer activating by itself.
Before replacing anything, I’d recommend one more test.
If the random activity stops with the touch panel disconnected, that would strengthen our suspicion that the touch panel is defective, although it wouldn’t completely rule out the control board. The range may also stop responding normally while the panel is disconnected.
My first suspect is the touch control panel, rather than the main electronic control board, especially since the problem seems limited to the oven light and timer functions.
One question: When the oven randomly beeps, do the timer or oven light actually turn on and off by themselves, or do you only hear the beeping sound?
That distinction will help narrow down which component is causing the problem before you spend money on another part.
