    Amp limiting controller?

    I have a frozen drink machine and for some reason it froze up the other night and stripped the plastic gear that operates the mixing paddle. Is there something that I could buy to put in line with the paddle motor that when it got to a certain amp draw that it would shut the power down to that motor? Thanks Michael

      You would have to know what your amperage is when the product is where you want it then you have to test the resettable fuse what there rating is and when they trip is two different things so it requires some testing

      But I would recommend checking a few things first

      Make sure that your temperature sensor controller or a mechanical thermostat is working correctly if has one

      It could have a refrigerate pressure control you have to know what type of refrigerate was used then take a pressure temperature chart to see what pressure at a given temperature because you could have a bad control or low on refrigerate charge you will need a set of gauges for this test

        A "resettable fuse" usually means a positive temperature coefficient thermistor that is low resistance until a particular current threshold is exceeded, at which point it goes high resistance. After it cools down it returns to low resistance, "resets".
