Daniel A Kerrville , TX January 24, 2020 Appliance: Model MES6770AAA Oven heating element burned out. I found the correct replacement part at Appliance Parts Pros within a few minutes of starting my search online. I ordered the part for a reasonable price and the part arrived a day early. No problem swapping the old part out for the new one. Unplug the oven first (or you might be shocked). Remove a couple of screws that hold the element into the back wall of the oven. Pull the element forward. Disconnect the wiring by pulling on the spade connector to unplug the old part. Reverse operation for installing the new part.
