Looking for a service manual or troubleshooting help for this range. Cooktop works fine. Bake and broil are dead. Checked both bake and broil elements and they are good. Checked temp sensor probe and it is good, 1090 ohms at ambient. Suspect failed ERC but since it lists for $146.00 at my local parts house I want to be sure that will fix the problem before I order it. I did not see any thermal fuses on the back wall. And assistance in solving this problem will be greatly appreciated.
