/diy/ - Do It Yourself

I can see the switches that are pressed on when the door closes getting broken and it not starting up as a result, but the LCD panel and lights should still work.

Having everything go out like that and it not be the fuse is odd. It might be a loose connection, but those things have great connections. If you open it up and poke around, make sure you safely discharge that massive capacitor first. Otherwise, you can get killed from electrical shock from it.

Yeah man tell me about it. The door shut and it was dead. It's covered in torx security bolts too, I don't have a driver handy either to just quickly disassemble it and have a look around. :(

I have a set of torx, but not security ones with the will hole in the center. I use a Dremel emery cut off wheel to slot them then use a flathead screw driver.

Most large manufacturers like to use the same parts in a large number of models. Therefore, most built-in microwaves are just a counter-top microwave inside an over-priced shell. Even among counter-top microwaves, several models usually share the same interior guts, the only difference being the control panel (buttons vs knobs) and exterior finish. So, you may be able to find several counter-top microwaves that you could swap into your shell.

If you haven't opened the unit up how did you check the fuse? Or did you mean you checked the household fuse at the box?

Exactly. My ancient Panasonic has 2 internal fuses that often opped when I slammed the door. Changing to slow blow fuses fixed it.

Aye, this is because of how the circuit for the door switches work. The door switches are a safety control that keeps the unit from running when the door is open. There are 3 switches usually. If any 1 switch connects while the others do not it will pop the fuse. So if you slam the door or have some crud built up over the years it can cause the switches to not engage and disengage at the same time.

I meant the fuse at the plug, pretty much the only serviceable part outside of the microwave.
That makes complete sense about the fuses, I tried to explain to my parents that one of the switches must have broke and short circuited and caused something to blow as a safety feature, but my father said that was a stupid idea. I'll get a lend of a security torx bit from work and have a look. Btw is one of you guys from up north? prominently from newcastle ? using the word 'Aye' ?

It's also a 'Diplomat MCW001 Microwave grill and oven' Could the possibly be a schematic out there that would show if it does have these door safety fuses ?

nope Amerifag here. :)

The fuse is normally in-line, inside, were the power cord enters the case before it goes through any electronics.
