Good day Oh Great ones;

    I have a Kenmore electric range C970-624182 built in 2003.  Through due diligence and safe testing practices using the schematics (318046743 Rev A) enclosed behind the control panel I find the following:

    Symptoms - Call fro Bake - Bake element does not heat, Call for Broil, Broil element does not heat

    Bake Element - Removed power, disconnect both yellow wires from bake element and measure approx 18.7 ohms between the terminals, between each terminal and chassis I read open cct.   Between both terminals each and the outer element reads open cct.


     Broil Element - Removed power, Disconnect both blue wires from the broil element and measure approx 31.5 ohms between the terminals, between each terminal and chassis I read open cct.   Between both terminals each and the outer element reads open cct.

     Temperature Probe - Disconnect wiring harness from the Spitfire ES300 EOC (SF5301-006B Rev 1 ??? Very difficult to read).  Measure resistance between harness pins 12 and 13 (both violet) reads 1062 ohms at room tempurature.

 
     Reconnect wires to elments, apply power - set clock, Open oven door - Light comes on.

     call for Bake 350 - Relays click, Bake, heat and preheat LEDs come on, I get approx 123 VAC between each bake element terminal and chassis, I get approx 123 VAC between each broil element terminal and chassis, 0 VAC between both bake terminals, 0 VAC between both broil terminals,

        ON the control board between test point and chassis

        Bake - 123 VAC
        Broil - 123 VAC
        L1     - 123 VAC
        L2 Out - 123 VAC
        L2 IN    - 123 VAC

        Elements do  not heat

    Call for Broil HI, Replays click, Broil and heat LED's come on, I get approx 123 VAC between each bake element terminal and chassis, I get approx 123 VAC between each broil element terminal and chassis, 0 VAC between both bake terminals, 0 VAC between both broil terminals,

    ON the control board between test point and chassis

        Bake - 123 VAC
        Broil - 123 VAC
        L1     - 123 VAC
        L2 Out - 123 VAC
        L2 IN    - 123 VAC

        Elements do  not heat
    
What is my next step???

Thanx
