I have a Kenmore dishwasher model 665. The thermal fuse 675813 keeps blowing. I have replaced the pigatils off the board that are supplied with the fuse kit. I was told by a Sears auth. service rep to keep the door filter clear. I do that with every cycle. Any suggestions short of burning this thing and throwing it off a cliff?
Mr. Larry (guru?)
The thermal fuse is just that It doesn't protect the circuit from over current although it certainly can open in that case. It is there to protect the board from overheating , thus the term thermal. The dishwasher could be allowing the water to heat too hot or the water heater in the home is turned up too much. The heater could also be shorted to case thus allowing it to be on even though the control is not calling for it especially if the polarity is incorrect to the dishwasher or the relay on the board could be welded closed so that the heater can't turn off even though the thermostat is satisfied. The best thing is to get a person who can check these things. You don't necessarily need to change the board with a fuse. I have changed many fuses with no other problems and verified that the machine was still working years later. sometimes the fuse just blows!
They needed to replace the control board when they changed the thermal fuse / larry

Mine is doing the same thing. Ordered fuse and replaced once, now (about a month of steady use later) it has blown again. Got a piece of wire stuck in there now. When a fuse keeps blowing, something is drawing too much current. Does anyone know what this fuse protects? Wondering if it's gonna catch fire without fuse protection.
I have a Whirlpool dishwasher and the thermal fuse keeps blowing. This is my third fuse in 2 months. Does anyone know what to do to solve the problem. It is Model DU943.
Any help is appreciated.

this is a thermal fuse measuring the temperature in the control box compartment. Replace the fan motor.
