Adding temperature control to an appliance AC calculations Ohms law?

I have an electric grill from overseas and am trying to add a temperature control to it. It has no internal components just a heating element. It has a 250v plug type on it currently but has 110v written on it. Right now it gets too hot and I am not sure why the 13amp fuse on the plug does not blow.

The element has a resistance of 6.3ohms so 120/6.3=19amps across a 13amp fuse?!?!

also 19amps x 120volts = 2280 watts so using a standard light dimmer will not work because they are rated around 600w.

It has 2 heating elements wired in parallel so if I rewire them in series I can get it to 24.8 Ohms 5 amps 600 watts but I have no idea if it will get hot enough ?

any help out there

Answer:
6.3 is cold ohms, you cannot use cold ohms to calculate current. the 6.3 ohms will increase to probably 10 ohms when heated up. the current is measured by ammeter when the element is heated up.

the dimmer switch is for light bulb of 300w, the capacity is not enough for heating element.

should use an "infinite switch" to control your heating element. the same "infinite swich" as used in electric range surface heating elemnet. this infinite switch worked on the principle of passing constant current through bi-metal and switch the current on for a few sec off for a few sec, say if the switching is 5 sec on 5 sec off you will have approx half of the heat.
