I am convinced that appliance repair sales people incentivized/paid to respond on forums to us homeowners are overplaying the simple thermal fuse that so commonly blows in dishwashers. I encourage any truly knowledgeable people to respond and logically debate these simple questions:
1. Does the thermal fuse located on the control board (e.g., QSC KSD301 250V 10A 85
oC) ONLY blow due to excessive temperature or does it blow due to either excessive temperature and/or current?
-I say BOTH, and probably most often due to excessive current
2. Does the wiring harness REALLY need to be replaced EVERY TIME it blows? Even if the wires look completely virgin, uncorroded, unoxidized?
-I say complete B.S. and most likely they are just packaged with wires to help justify $30 for a $1 simple thermal fuse. If the wires look bad, then yes, replace them.
Let's debate! Share your real world experiences!
