    Why won't the heater come on?
    I have a 9inch by 3inch by 6 inch under cabinet heater 240volts that is mounted in the wall of a bathroom. There is 110 to each of the two legs and one side each of the two limit switches. The power doesn't pass to the other side of the switches either one and on to the heating elements. I pulled one of the nickel sized sensors(limit switch?) with a male electrical tab on each side. Though they look very new and shiny could they both be bad?
    Thank you for any suggestions
    The thermostat is calling for heat and both current wires hook directly to the little switches I described above. Should I simpy jump over the switch for now and see if that allows the
