    Can someone please tell me what this part is, what is its function, how can I check if it is OK and what can I substitute for it? The part in question is in series with the phase input to a heating coil in the base of a Tomado rice cooker. The unit is rated at 700Watts at 220VAC .

    Looks like a self resetting breaker or a thermal fuse. When it gets too hot it opens and current stops until it cools off

    Thank you Kermit2 and shortbus for replying. Should I get a resistance reading from it? I get no indication in either direction so can I assume that the part needs to be changed?

    If the fuse were well, you'd get a continuity reading on either direction. But that fuse is obviously blown, just get an equivalent temperature replacement as shortbus has suggested.
