I have a samovar (an electric tea kettle) with a bad thermal cut off fuse that runs immediately after the 120v input plug The TCO is rated at 4amp and 152C. I cannot locate this fuse anywhere but he

$30 seems awfully steep for this part.

Would it be safe for me to replace the 4AMP TCO with a 10amp 152C and simply add a 4amp fuse immediately before or after the TCO? Intuitively this seems like it would work, more than 152C the TCO burns, more than 4amps the other fuse blows.

Thanks!
