Stove control panel suddenly stopped making beeping sound?

Hello all,

The stove is acting up again. Last time it was the igniter, which was fixed with help from this forum. Now it decided it wanted to be quiet.

Tapping the keypad doesn't result in any sounds, neither does coming up to temperature nor a timer going off.

I tried power cycling the stove, enabling/disabling control lock (which, as expected, doesn't result in any beeping), and enabling/disabling sabbath mode.

Any suggestions?

Thanks,
Chris
