This is an electric oven that will not bake or broil. But the display works and so does the light and fan.
This is what I did to diagnose the problem:
First, I measured the sensor which is good since it measures 1075 ohms at room temperature.
Next, with my meter at the control board terminals, I read 240V across the control board's L1 and Bake relay terminals with the oven plugged in and in standby. This means to me that there is continuity through the bake element and the limit switch.
Next, keeping the volt meter leads on the L1 and Bake relay terminals, I turn the oven controls on to the Bake setting. The voltmeter continues to read 240V. So the relays are not closing (if they closed, I would get a 0 volt reading across the relay terminals). Then after about 30 seconds the bake display shuts off, and the meter still reads 240V.
Then I did the same thing with the L1 and Broil terminals on the control board and got the same results.
So, it seems like the Bake and Broil elements are good (at least there is continuity through them), the limit switch is closed (there is continuity through this), and the sensor is good.
Does it need a new circuit board?
Thanks to anyone who helps. It will be much appreciated.
