Product review (4 stars): It fixed my microwave
I my case 4 of the buttons failed to respond, but no error code is shown on the display, despite the fact that all troubleshooting aids indicate that an error code should be indicated when the panel malfunctions. I tried cleaning the ribbon cable connector contacts with both denatured alcohol, then with a pencil eraser after the alcohol didn't do the job. The eraser didn't work either.
A bit of research indicates that this component is a common failure point. The microwave is 4 years old.
I could have purchased it from other suppliers for less, but past experience gives me the confidence that Amazon will back the purchase up should I have any issues with a supplier.
I suppose that I could have rated it 5 stars. It does do the job and I am satisfied, but how can I love a replacement microwave keypad?
