The bake element on my Frigidaire Electric range model GLEF378CQB just won't work. Everything else works except I did notice the broiler element isn't as hot as it should be. It started blowing the breaker switch about a year ago when 3 burners and the oven was on but thought it was just overload. Then the bake element just stopped working, replaced it, still dosen't work, no voltage at all from the element wires. What should I try next???
