Identify Component in Urn(Big Kettle)

[StudentSA]

Good Day

I'm repairing an Urn and one of the lead of this component is fried as well as the connecting wire to it.

Please could someone tell me what component this is.. It is merely mounted on the surface with what I assume is heat transfer compound.

It's a thermal cut-out switch (or self re-setting thermal fuse, if you like). The urn bottom gets too hot (due to no water in it, or whatever), and the thermal switch opens. It will, normally, close after it has had time to cool.

It would be in series with the heater element.

There should be some kind of marking on it that would indicate it's threshold temperature.

hi,
This is the device, you can buy them in a range of temperatures.

Thanks,

I see that it was in series with the element, the only text on the device is "60" (which if it is a temp I assume its in degC). This confuses me a little because the urn needs to boil water at higher than 100degC, will this 60degC thermal cutoff switch not restrict the urn from heating the water to that level?

Thanks,

Me Again,

I cant seem to find a replacement "easily". Would it be possible to use something like this Cutout as a replacement? Otherwise I`ll look into purchasing it online and shipping from where ever it is available.

Thanks,

An urn is for holding and serving, not brewing, so the temperature sounds right. If it were a percolator, maybe not.
