broiler works but bake element doesn't. Replaced heat sensor and bake element. Turn unit to bake and 350 degrees and checked voltage at the bake element and I am getting 120 volts on each side of element.
You will need to access the control board and check voltage. You will want to test from L2 to bake with the unit set for bake. If there is 240 vac at this point then the control board is faulty and would need to be replaced.
How do I get the knobs off the old part and then how do I put them on the new part?
The knobs for the clock timer are attached to a shaft and they are just rubber knobs. When you pull the rear cover of the control panel off and take the clock out, the shafts for the knobs should be exposed and you can push the knobs out.
Our oven is burning our food and we get an F1 code. Other than that, the oven is running and the clock and timer work. Any suggestions on which part to replace?
The F1 error code indicates a runaway temperature. You will want to test the oven sensor for resistance. The resistance value should be 1090 ohms at room temperature. If the sensor does not have this resistance then you will need to replace the sensor. If the sensor checks ok then you will need to replace the oven control.
