By using the online chat I made sure the part I was ordering was the correct replacement part for my GE Profile oven. It arrived in two days. It was a matter of unplugging the oven; remove two screws to remove the old part; then plug in the new one and replace the screws. Note that we had already replaced the oven element (which was purchased the same way) about two years prior. We have now purchased dishwasher, refrigerator and oven parts from AppliancePartsPros and happy each time.
