What are the two most common problems that may occur in an electric stove?

The two most common problems that may occur in an electric stove including GE JB735SPSS and Whirlpool WFE505W0JS are burner not heating and oven not heating. First, burner or coil not heating is most common, caused by burner element burned out after 5 to 8 years where coil at top breaks and shows no continuity, costing 20 to 50 dollars for replacement coil, or infinite switch failed that controls burner temperature, costing 20 to 40 dollars, or burner receptacle or terminal block burned due to loose connection causing arcing that melts plastic, costing 15 to 30 dollars. Symptom is one burner not heating while others work, or burner heats intermittently. Second, oven not heating or not baking is second most common, caused by bake element burned out at bottom of oven after 5 to 8 years costing 30 to 80 dollars, bake element not glowing red when oven set to 350 degrees, test for continuity with multimeter, or broil element burned out at top, or temperature sensor failed at 20 to 40 dollars causing inaccurate temperature, sensor at back wall should read 1080 ohms at room temperature, or control board relay failed costing 150 to 400 dollars. These two problems account for about 60 percent of electric stove service calls according to technician data. Other common problems include control panel buttons not working and door not closing properly.
