Dilant P Reston , VA July 12, 2016 Power button and couple of other buttons stopped working; no indication of heavy use Replace the button panel. The button circuit is fused into the panel. So, whole panel has to be replaced. Panel is pretty expensive ($65) compared to new microwave, which is now on sale ($150). Fixing was straightforward - remove the panel from microwave, unwire the connections to logic board, remove the logic board and aluminum tray, replace the panel and reverse.
