Earlier this week my wife called me and told me the lower oven launched a bunch of sparks out while she was using it. Naturally a burnt out element. I replaced it and am still not getting heat. It looks like I only have 120 volts reaching either element for the lower oven but the upper works fine, and I have 240 at the main terminals.
The lower thermostat is giving me 1080 ohms, and the upper is reading as broken, which is strange.
The high limit is reading 2 ohms.

Any thoughts on where I should start?

Hi,

I don't see a high limit thermostat on this model, can you point it out to me.

Here's the parts diagram for your model:

If your not getting 240 volts to the lower bake element, that means your clock oven control board went bad too, likely shorted out when the bake element sparks were flying.

The clock oven control board has been discontinued:

Time to range shopping.:)

Looking at the wiring diagram, it is listed as upper broiler hi limit, though I don't see it on the parts, it is located directly above the upper broiler on the back. And yeah, it looks like I am only getting 120 to the lower elements.

Ok, it should measure 0 ohms:

Both oven sensors should ohm test at 1050 to 1100 ohms:

Its odd that your upper oven sensor is bad, but that oven is working fine?

Yeah, this is one of the things that threw me off. The lower is ohming at 1080 and the upper is reading O/L. I thought maybe it is just the connector but without pulling the thermostat I can't confirm. I traced the wiring back to see if something was crossed because it didn't make sense, but no dice. The wires all appear to go where they should.

Is it possible that the broiler upper limit would cut out a phase on the lower oven? That doesn't really make sense to me.

On the board, red connector pin 4 to white connector pin 4 should be 220 VAC

Correct input voltage and only 120 output voltage = bad board
