Product review (5 stars): Fixed heating problem
This fixed my dishwasher problem of not heating.  At first I thought it was the heating element, however the resistance measure was around 30 ohms, so it was good.  Did some research and found out that this part was responsible for it not heating.  Replaced and the dishwasher heats great now!  It was easy to replace for my GE model; only a couple of screws and the wiring harness.
