Faulty Microwave Interlock Switch Repair 

Will not matter. Its just an on and off switch much like your light switch in your home.

that's not so easy with an intermittent issue

He didn't know. He took a chance. He didn't use a tester. Deal with it.

most new microwave capacitors have a special diode that automatically discharges the capacitors.

"Most" might not cut it! Simple enough to short across the capacitor before you start? Any downside to doing that?

@@rkeithphillips8233 It's actually a resistor (not a diode like the above comment claimed) and I've never heard of a microwave oven capacitor that DIDN'T have one attached. And it's not hard to tell if it has one. It is literally soldered across the terminals of the capacitor. It discharges the capacitor to a safe level in about one minute. So just unplug your microwave and wait one minute before opening it. Then look to see if it does actually have this safety discharge resistor. If it does, measure the voltage with a multimeter to verify that the discharge has been down to a safe level (if it's still 100v or more, manually discharge it by shorting it with a screwdriver, and even that is just playing it safe, as your body can handle DC voltage safely quite a bit above that up to about 200v). What if it still has some charge left like 50v to 100v? Don't worry about it, because that much DC voltage is actually safer than the same AC voltage. I'll explain more about this in the next paragraph. Once you verify the capacitor's voltage is safe or (or short it to remove it completely) then you can perform the maintenance on your microwave oven completely safely. As I mentioned above, there's a difference between AC and DC electricity when it comes to safety. I saw another RU-vid video showing a guy demonstrate this. He showed that 120v AC will shock you, but if you rectify it and charge a capacitor with it (which actually gives you 170v DC) it doesn't shock you at all. The reason is that your skin has a HUGE resistance to the point that it's practically an insulator (I've measured mine with a multimeter and seen it has about 20 to 30MOhms of resistance). However, it's quite thin, so it will appreciatively couple an AC current (even if it has a frequency as low as 60Hz), and the inside of you body is quite conductive, so the total AC impedance of your body (skin + internals) is somewhere somewhere between 1kOhm and 10kOhm. This means that at 120v, your body will conduct between about 12mA and 120mA, which ranges from a quite painful (and possibly, but unlikely, deadly) shock to a shock that is almost certainly fatal. That's why the 120v AC from an outlet can electrocute you. But why I say that if you can verify that the DC voltage on the capacitor is below 100v, you are completely safe.

No the top switch is primary and is normally closed as is your secondary switch that is on the bottom now your moniter switch is normally closed that one is in the middle

@@jenniferraber-greene9495 I think you have a typo...the primary (top) switch and the secondary (bottom) switch are "normally open". You said they were "normally closed", which is wrong! The monitor (middle switch) is "normally closed". Bottom line look at the diagram on the switch casing and note if one of the terminals is in the position or is lined up with the NO or NC marking.

charles howard you discharge the capacitor by crossing terminals with needle nose but be careful not to touch any metal the shock can kill u

I don't know what the hell he was talking about, but those are standard spade connectors. Sometimes they're just squeezed tight.

So after taking a closer look, it appears some microwaves indeed use positive locking female spade connectors. To release these properly, take something small with a fine tip, like an eyeglass screwdriver and while supporting the connector, take the screwdriver, insert it between the m-shaped part and press lightly while pulling. The terminal should release very easily if done properly. Think pushing a clip out of the way, because that is literally all it is. Do not use my original suggestion. If they are high quality plugs, you'll probably wind up damaging the switch trying to force the plug off.

Whirlpool Jet Chief has this tiny metal button that clips in its switch connector . Cookworks microwave doesn’t . Connectors get greasy and suitable sized flat screwdriver end ease it

+cool boy dude What's your question?

It's your probably your magnetron but would get your capacitor and diode checked to but the magnetron is what sends microwaves with is what heats if so better of getting a new microwave repair is costly.

+cool boy dude I'm not sure, maybe next Monday? Any suggestions for a topic?

+cool boy dude Good

Do that with your video.

Yep, I tested mine ?? You can even easily disassemble these micro-switches, to see what is wrong with them. Meanwhile, by drinking beer, my oven has been repaired twice, for free. Yep, a few beers did the trick. Off I went walking to the beer store with my foldable cart on a rainy day. On the way there, I spotted a microwave oven that was placed at the curb for disposal purposes. So on the way back home from the beer store, I dropped this oven into my cart and took it home with me. After drying it off, I took it apart and it turned out to have the same micro-switches, the same AC fuse, and the same thermal fuses, and they were all working perfectly. So, after replacing one AC fuse, one thermal fuse, and one dead micro-switch, my microwave oven worked perfectly again, and still kept going on strong many years later. Today, I had to replace another one of the door micro-switches, but I still had 3 micro-switches to spare from the trashed oven. Also, the curb trashed microwave oven turntable, now functions as a lazy susan for one of my tall plants that needs to be rotated now and then.

Because he didn't. Deal with it.

+cool boy dude You are! First view and like too. Thanks! That video just finished processing 45 seconds before your comment too.

Set higher goals in your life.

For those that are too lazy and/or simple, yes.
