I have a samsung otr microwave SMH9151STE and it powers on, but does not heat or rotate the table top. The clock, light, vent work. The last thing it was used for 5 mins for chicken pot pie lol.
THanks in advance,
Answer Hello Eric. You will need to check the door switches and make sure they are good. Also, check the H.V. circuit to see if any of the parts are damaged. Be careful as this is live power and can hurt or even kill you if you do not know what you are doing. Usually it is best for a certified tech to test these components on the unit. You should be fine testing the door switches in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
