Control locked Keypad doesn't work, screen says locked

Unless there is moisture or grease on the control circuit board, it's likely failing membrane keypad.
There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.
For model GH7155XHS0, the exploded view and parts list are here:

The part number is 8183977 "Controller Sub Asy"

You can order the parts from the Pros here.
Some connectors may have a lock.

Then carefully (since the display is made of glass) move your circuit board to the new frame, and reassembly is the reverse of disassembly.

If you have a stuck key or non-responsive key, most of the time you will have to replace the keypad for this microwave oven repair. If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control. Most of the time, it is the keypad that needs replacing, but a small percentage of the time it can be the control. Check the tech sheet if they can point you to the right part.

No! I'am afraid not, the problem is in the keypad control board, the whole assembly must be replaced, the part alone will cost around $100.00 or more depending on make and model.

The problem is more than likely in the microprocessor control board, sometimes a bad relay, or poor solder points.

You have a failed membrane keypad.

On this model, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

It is part number WB56X10824 and you can order it here for $124.12.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

At our Web site ,we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move the circuit board into your frame. Be careful - the display is made of glass.



Some connectors on the relays may have a lock:
