Re: time showing on panel. No functions work.when I touch...
You can try to reseat the serial ribbon but it sounds like a board problem. to reseat the ribbon, unplug unit. remove the case for counter top models, otr models need to remove the grille, and the control panel screw, lift up and pull out at the top. the serial ribbon is a flat set of wires at the top of the board lift on the connector latch to loosen the ribbon pull it out, push it back in and relatch. close up the control panel before plugging back in. if it works great, if not it is time for a new microwave boards are very expensive.

A lot of the time when that happens the touch pad is bad and may have a colappsed air pocket on a pad. ( it makes the unit think you are pushing a pad ) The only way to fix it is to replace it (the touch panel) . Did you see any numbers coming up in the display. Like if the 3 pad was bad and making it beep it may have been showing a 3 in the display,. Always possible it could be a bad main board. But most commonly I have found it to be the touch panel. Try to unplug it and then plug it back in and try to set the clock. when you do, try each number pad and see if they all work. See if any feel different.
The code on the screen indicate electric panel fault resulting from the touchpad malfunction.
The touch pad on your microwave oven acts as the brain of the appliance. It not only contains the buttons that you use to enter cooking settings and times, but also controls the function of the entire microwave. If the touch pad malfunctions or breaks completely, the microwave will cease to function. In this instance, the broken touch pad must be removed and a new touch pad must be installed, to restore functionality to the microwave.
1 Unplug the microwave from the wall outlet.
2 Remove the two screws, located on the front or top of the grill at the top of the microwave.
3 Pull the grill off of the microwave.
4 Remove the mounting screw from the top of the control panel.
5 Lift the control panel up and out to loosen. Look behind the control panel to ensure there are no metal tabs securing the control panel in place. If there are metal tabs, gently rotate the control panel to free the tabs.
6 Transfer the wires from the old control panel to the new control panel one at a time to ensure that the wires are properly installed.
7 Install the new control panel into the microwave and secure using the mounting screw that was removed.
8 Replace the grill from the top of the microwave and secure it using the screws that were removed.
9 Plug the microwave back into the wall outlet.
Hi, this is usually a bad touchpad. The way to tell for sure is to kill power to the unit, take the control panel down and unplug the ribbon connector that connects touchpanel to the clock. Put it back together and reapply power. The clock will just sit there blinking and, obviously, the buttons won't work, either. if the beeping stops, then the touch panel is bad. And If it still beeps, then you have a bad clock.
The oven operation can be locked to prevent the microwave from accidentally being turned on. All oven functions can be locked.
To Set: Touch and hold the CANCEL/OFF Pad for three seconds. The Display shows “LOCKED” and the oven beeps.
To Cancel: Touch and hold the CANCEL/OFF Pad for three seconds. “LOCKED” disappears from the Display and the oven beeps.
If this does not work, then try a hard reset: Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again.
If it still fails, you probably have a problem with the controller.
