if you can slide out the oven slightly with power off, you can find a wiring diagram.. more than likely you are only getting 110vac to one leg of the element ... Need to determine where you are getting the electricity from and which leg you are losing 110vac ... need to check which color wire you are getting 110vac .. check each leg to ground and that will tell you which wire is "hot" and which is not .. when you determine which one is not "hot", follow wire back to either a safety t-stat or relay board .. ( be careful as working with live electricity is not easy ) .. remember to check wires to elements with the wires off the elements . .. i have needle nose vise grips that i use to hold the wires so that i dont let the wires ground out ..
