This instructable actually ended up saving my "Bonavita 1.7-Liter Variable Temperature Digital Electric Kettle - BV382517V"! Thanks!I had had it for a little over a year when it simply stopped heating. When I disassembled it, I was measuring voltage at everywhere but the resistance. I've never had any reason to take apart a kettle before, so I wasn't aware of the thermal fuse until I saw this DIY. An Ebay order and a week later the kettle was working like new again! Which was great because I love this kettle and it's discontinued.Two notes though.First, I wasn't able to find any info corroborating that thermal fuses have a polarity. And honestly, it wouldn't make too much sense to begin with, given that the heating element is powered by AC. That and the fact that fuses in gene...see more »This instructable actually ended up saving my "Bonavita 1.7-Liter Variable Temperature Digital Electric Kettle - BV382517V"!

I've never had any reason to take apart a kettle before, so I wasn't aware of the thermal fuse until I saw this DIY. An Ebay order and a week later the kettle was working like new again! Which was great because I love this kettle and it's discontinued.Two notes though.First, I wasn't able to find any info corroborating that thermal fuses have a polarity. And honestly, it wouldn't make too much sense to begin with, given that the heating element is powered by AC. That and the fact that fuses in general don't tend to be polarized (think car fuses) makes me think that the thermal fuse is non-polarized. If someone can point out that this is wrong and why, I'd be just as happy to know.The second is, if you want to avoid soldering the thermal fuse (and possibly tripping it or having to use a heat sink), what I did and what I'd recommend is cutting the connector off of a pair of crimpable electric connectors, or cutting in half a crimpable electric union, and that way you can use it to simply crimp the thermal fuse to the wire as it originally was with little hassle at all. And I doubt that type of person that repairs their coffee machine or kettle in this disposable age doesn't already have some crimpable electrical connectors laying around somewhere.
