I called a repair place. They charged $54 to diagnose, (said it needed a new latch motor) then wanted $220 to complete the repair. I checked online prices and did it myself for about 15 minutes work and the latch motor itself ($44?).
Was necessary to uplug the range, pull it away from the wall and remove the back panel sheet metal, then 3 screws that mount the motor. Replace motor, reattach sheet metal. Plug in. Done. Ready to bake cookies.
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.
