Turned power off at electrical panel. Pulled oven away from wall. Removed back cover (6 screws), then unplugged wires from old receptacle. I had to pull the squeeze clips backwards & break them to remove the old receptacle - couldn't squeeze them enough to remove them otherwise. The old receptacle came out through the inside of the oven, and the new one snapped in easily from inside the oven as well. Replaced wiring, installed new bulb, restored power & tested. Replaced back cover. Good time to vacuum under/behind where the oven usually lives before sliding it back to the wall.
The repair was nothing, but the diagnosis was a bit tricky. After carefully looking at the burner head, (cast aluminum) I pretty much figured out that the 4 small cast aluminum bumps that keep the burner cap positioned up in the air the correct amount to allow gas to flow under the cap, were worn down, preventing the gas from exiting properly by the igniter. My guess was correct. The new burner head solved all my problems. I love Parts Select for the ease of finding the correct parts and how fast they ship their orders. Great company, great service. Keep up the good work
