Hi, thanks for looking at my post.

The Rice cooker in question is from China where they use 220 volt 50
hertz. I want to hook it up to 220 volt 60 hertz.

In case you've never seen a rice cooker, it has a paddle switch that
you press down to put it into "cooking mode" and then after a time the
switch moves by itself to "keep warm" mode. This one also has a toggle
switch for cooking "rice" or "soup."

I'm pretty sure the heating element won't mind the different frequency
but do you think the timer or whatever it is that moves the switch will
be adversely affected?

Thanks for your help, Richard

It is unlikely you'll hurt it by running on a higher frequency. If it
is a line referenced timer it would time out sooner, but it may have
an independent time base or just sense moisture or temperature rise.

Clock motors and transformers run cooler on 60 versus 50, and motors
run faster.

If it is necessary to put a fixed volume of rice and water in it, each
time you use it, it is likely they do use some kind of timer. If you
can vary the amount of rice, chances are it senses the rate of
temperature rise, or temperature above boiling as the water is
absorbed and vaporized.
