I have a dishwasher who's heating coil stopped working. Looked at the bottom and the hot wire was charred and broken away from something.... that something was cylindrical and had another wire going to it.
I'm guessing it was a thermal switch that didn't do it's job cause it was pretty charred and burnt up. But now I need to replace it and do not know what rating to use.
On the dishwasher it says it uses 2.5A for something 7A for something else and 10A operational. So I guess it's saying it uses 10A on average.
The heating coil has a resistance of 14Ohms so I'm guessing at 120V or so it should draw about 8.5A total. (which is a bit more than the 7A which I suspect is for the heating coil)
But how to overrate for thermal fuses? 12A fuse work fine or what?
I'm actually thinking of putting a circuit breaker or larger fuse in series because it was poorly designed and luckily didn't burn down the house.
I'm just not sure how what size fuses I should use. I imagine 11A or so would work just fine as the heating coil probably increases resistance when it heats up.
Maybe an 11A thermal and 12A breaker/fuse?
