Yes, lesson learned the hard way. Any recomendations in terms of MW brands? Before getting this one we used to live in flats with built-in MWs – all from brands that don’t seem to sell stand-alone ovens (e.g. Siemens). Thanks again
When I remember the Sanyo MW that my parents had and that was still going more than 25 years after they purchased it…
Update. Tried out the new membrane and got the exact same problem. I’m guessing that means that it definitely has to be the PCB, right? Also, the start button has stopped working again. To be honest I’m almost tempted to just sell this MW for spares and get a new one. Quite disapponted with Samsung’s quality. Bought a Samsung TV at the same time as this MW and it also starting showing some faults after 1.5 years or so…
Thanks. I ordered a new membrane and we’ll see if that does the trick or not. If that doesn’t do the trick then I’d imagine it’s the PCB. In any case, fingers crossed. Thanks a lot for the help
Thanks Dave. Unfortunately the way the ribbon is soldered and glued to the membrane doesn’t allow me to clearly see where each connection leads. However, I used the terminals in the ribbon and tested all possible combinations of the terminals while pressing a button at a time until I got a beep (or at least a change in the resistance). So, for example, for the “stop” button I got a beep with “pins” 6 & 16. I seem to have gotten a beep, even with some of the buttons that work intermittently and a “chronic” one, but didn’t get anything with one of the “chronic” buttons. However, I might have skipped a connector when trying them all out so wouldn’t take it as a fully reliable indicator.
It is really odd. In the morning of the 14 buttons in the pannel, five (including the start button) weren’t working. After all this testing there are five that are still not working – four that were not working in the morning and a new one. However, the start button is now working. Everything else in the pannel including the display and the know seem to be working fine.
Thanks! For reference I found a picture of the switch membrane at https://ineedparts.eu/products/control-board-for-samsung-mc28m6075cs-microwave-oven-de96-01040a. So, just to make sure that I understand, what should happen is that if, for example, for the button on the lower-right it goes back to the first and third connectors in the ribbon. Then, using the continuity test function in my multimeter, if I put the leads on the first and third connectors of the ribbon and press the button, I should get a beep for continuity, otherwise the membrane might be broken, right?
Thanks again.
