My Samsung oven is not getting hot on bake cycle and broiler not glowing red hot on broil cycle. I believe it's because the broil element is not getting red hot although its hot to touch. Broiler element resistance measures at 17ohm which is within range. Temp sensor resistance is 1200 ohm. Getting 120 volts to each terminal compared to ground. However, when testing voltage across both broiler terminals voltage is zero. How could that be? Are the two 120v currents cancelling out? Is there a control board fault?.

Thank you for any help.

The broil element needs 220V AC to operate. L1 is 120V AC and L2 is 120V AC When it's working correctly the element becomes the load. You're missing one of the power legs to the element so now the load becomes a "wire". The voltage doesn't stop at the element. Since each leg of power is only 120V AC that's the maximum voltage you can measure to ground. The reason you get no voltage measurement across the element terminals is because you can't measure voltage on a single wire. It would be the same as trying to measure the voltage to a light bulb by disconnecting one of the wires going to the light bulb and connecting your meter between that wire and the spot where it was connected. On your machine, both legs of power (220V AC) for the broil element comes from the board. If the bake element is working correctly the board is getting the 220V AC supply voltage so the problem is the board.
