I was trying to replace a thermal fuse from my rice cooker and it seems that it has a 250V/10A label on it. I haven't been able to get a similar one nearby which means I'd have to order it online or travel to an electronics bazaar in the capital and boy I hate the traffic over there. I wonder if normal fuse with similar ratings would work as well?
Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature and not to excessive current (unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature).
Maybe both, ambient melts the internal wax (if thats the topology) and a little spring seperates the contacts, or excessive current flow heats the fuse (via resistance) and that does the same thing but self heats.
Hi guys. A little update here. I have replaced the fuse with a higher rating and it still trips. The rice cooked well though. I suspect it tripped during the warming period.
Any other suggestions on the repair? Or should I just scrap it already?

I'm going to bore you now, changing the fuse for a higher temp isnt really safe.
Sounds like one of the elements has shorted or the 'stat isnt working.
