How to replace a blown resistor and added conundrums?

Block Image

Block Image

There is a resistor or some kind of fuse soldered to the board that needs to be replaced - Has burn marks on it and will not complete a circuit when tested with an ohm meter.

Is the best option to cut it out to see if I can match it up or look for a new board?

Can you make out all the markings on it?

It's green on one end, blue on the other. On the green end is a darker green band followed by some discoloration (blown fuse look) and then a black, gold and the last band is brown on the blue end.

@timetothrive post some pictures of what you are looking at with your Question. Use this guide在已经存在的问题里加入图片 for that. That way we can see what you see. right now it sounds more like a resistor than anything else

This appears to be the only casualty. I'm thinking my best bet is to cut it out on either side and attempt to solder the new one up high rather than low on the board? What do you think?

Also, there may be another problem by the looks of that burned area on the yellow thingamajig?

Same broken kettle, same blown resistor, same scorch marks on the yellow capacitor. Thank you, I'm going to order the resistors today and see if replacing the resistor brings the kettle back to life.

Hi,

If your resistor has colours of Green - Black - Black - Gold - Brown it should be a value of 50 Ohms (5+0+0 x 0.1)with a tolerance of +/- 1% (I cannot see the second colour band that well in your picture to be sure of its colour so not entirely sure of its value therefore the resistor value is somewhere between 50-59 Ohms)

Also judging by your picture it appears to have a 1W (1 Watt) power rating. The scorch marks on the yellow component (which is a capacitor), may have come from the resistor when it overheated.

If you can't get to the underside of the board to unsolder the resistor, cut the faulty resistor as close to the body as possible leaving the soldered "legs" as terminal posts to solder your replacement resistor to.

Be aware that there is always a reason why resistors burn out. Usually it is due to excessive current caused by another faulty component in the same circuit path. It may be that if you replace the resistor that the new one will also burn out as well.

Here is a 5 band resistor colour chart to work out resistor values

The resistor in ours burned out as well. Fortunately it burned in a different place. Matching yours and ours I think the color bands should be Green-Brown-Black-Gold-Brown giving 51 ohms +/- 1% . The original may have been 1 watt but I installed a 2 watt resistor. I purchased 5 resistors on eBay for $2.68 with free shipping. So far it has been working.

Hi @ Dean Hjelle,

Thanks for the feedback / update.

Every little bit helps.

Cheers.

It worked until today. We used it 2-3 times a day. It lights up and looks like it's working but no heat. I checked for conductivity across the thermal fuse and there is none. It's an AUPO BF192. I don't know if the resistor problem and this one are related.

Hi @ dihjelle,

At least you can get a replacement thermal fuse to see if it works again.

To me the images of the fuse in the link indicate that it is a "sealed' unit so you cannot tell if the fuse ruptured violently internally or just broke away possibly due to fatigue. it can happen.

Only option is to replace and see what happens. At $US1.00 each it's worth the gamble.

Cheers.
