GE service is brutally efficient. I called them once becuase I heard a clicking noise in my dishwasher. Within an hour a tech was dispatched to my house via an email he received on his wireless laptop.
Before I even knew what was going on he had found a small piece of wire that had gotten stuck in the dishwasher pump, made a joke about only charging me a 'learning fee', swiped my credit card in his laptop for over $200, and was out of my driveway. I don't lose money that fast at the casino. It was truly impressive.
When the touchpanel display went out on my GE stove, I called them again for an estimate. They charged me $45 for the estimate, but they gave me the part number I needed for the display. I found it from somewhere on the web for $300 less than they were going to charge me.
I think this is the site I used:
