I don't know if anyone else has experienced blown fuses in their recirc toilet or not, but I did over my holiday trip. >
Today I went out and bought a 6 amp 12vdc re-setting circuit breaker from Cole Hersee ($2) and will wire it in place of the TM installed 5 amp fuse.
From now on, I won't have to worry too much about my toilet! :-X May have to worry about other circuits, but hey... First come first served. And given the prominence and importance of the instrument in question - what would you do? ;D
