Frigidaire range - Broiler didn't work. Checked element - about 20 ohms (OK). Problem was oven control unit. Access was difficult - slide-in range so controller was in front. Five wires, four connectors and two ribbon connectors. The ribbon connectors were a challenge - needed magnifying glass and good eyes. New controller fixed problem.
