i bought a Whirpool when i'm using it it shut down after about 20 minutes i let it cool down then restart it run again, the other day my cousin use it until there was smoke comming from it, my home current is 110volt 50Mhz but the power on the pum read 120volts 60Mhz will that make a difference to cause the pump to over heat, i call american standard they said The motors are equipped with a heat sensor so if they get too hot they will turn themselves off, is there a transformer/converter to convert my power source from 110 50Mhz to 120 60Mhz

if you are in North America, your pump needs to run on 60hz, the heating element will probably work fine on either 50 or 60hz. Hz is how many times a second the current alternates, it effects the speed of the motors and can make them overheat.

What makes you think your home current is 110volt 50Mhz?

That's pretty odd for anywhere in North America.

Voltage is commonly said to range from 110-120 volts. (I think the standard is supposed to be 116.83 volts RMS, ±7 volts.) But this minor variation won't matter much, except that some appliances will run harder at lower voltages.

But the drop of 16% in frequency from 50Hz to 60Hz could cause problems. Do your electric clocks run slow, for example? They would lose over an hour a day, if driven by this frequency.

I think it's rather unlikey that your house current is really what you think it is.
