Question about Samsung SMH7174BC Microwave Oven
Is it possible that grease or moisture got into the controls? This can happen when cleaners are sprayed directly on the keypad; when boiling is done on the stovetop without the hood vent fan being on; when the hood vent filter is clogged; or due to restricted airflow in exhaust. The best way to check the airflow is to turn the hood vent fan on and use your hand to feel at the exhaust outlet outside the home. Moisture can cause the keypad or control board to short to some degreee, and produce odd results. It may clear up, but sometimes it requires that the keypad be replaced or that the board be professionaly cleaned.
