content: Hi all.I own an old microwave oven from Samsung, a CE107MST :http://www.kringloopatelier.com/images/com_hikashop/upload/6291_2.jpgThe catalogue picture is this one:https://images.samsung.com/is/image/samsung/nl_CE107MST-XEN_001_Frontbut it's not the one I have.It's a pretty good combo IMHO (microwave + traditional with quartz tubes) but is out of warranty, I have to say.Recently, I saw and heard a loud flash in the oven right when I opened the door — I saw it happen by the lamp that turns on when the door is open. Consequently the breaker also tripped and I feared the oven was destroyed. I tried and took it apart and took the lamp out, which turned out to be blown. I couldn't replace the lamp (it's a proprietary lamp+socket dedicated assembly) then reassembled the cover and protecting plastics and the oven went fine again.There's just one exception: the plate no longer rotates and I don't know if the motor is damaged or if it's something else. I inspected the PCB and saw nothing that would indicate a component had fried/exploded. I couldn't remove the PCB though so couldn't inspect the back side. There's a fuse next to the mains PCB. It is still intact. So something's probably blown but I don't know what it is.I of course tried to contact Samsung in my region but they only send technicians and don't provide repair/service manuals — you might have BTW no idea how tedious it is to have the operators *actually* confess that, they always dodged my questions, it's flabbergasting, but well, I digress. After going in circles I decided to ask here.Does anyone know where I could find service manuals for that kind of oven? Or does anyone have enough experience in the matter to offer some guidance?Any help/suggestion/hint/info is greatly appreciated.Cheers and thanks a lot in advance.

content: I'd suspect one of the door switches. One of them is likely responsible for turning on the light or the light and motor together depending on if the door is open or closed.Highly possible the switch contacts were damaged when the bulb shorted out.Follow the wires and you'll find what you're seeking.

content: Quote from: jonpaul on October 22, 2022, 12:56:34 pmWell, sorry for the delay. Out of curiosity: why is it that a motor, of which I expect it to be the most robust part in that assembly, is failing to a point it is a "common failure" ? What does that thing have to make it fail so quickly (relatively speaking, of course)?EDIT:Nevermind, a couple web searches gave me a few hints
