Crosley oven 50 degrees over setting

Crosley Mod CRE3875PWA

I checked the temp probe at different temps and at connection at control. The ohm readings were in the right range. So i replaced the control today and still have same problem
If I set at 350 the temp will rise to 400 then back to 345, and up to 400 and so on.
I was sure it would be the control but now I am puzzled.

I am baffled. You replaced the electronic control board and the temperature sensor probe checks ok.
That doesn't leave much of anything else.

I'm wondering if the temperature probe is breaking down under high heat.
There are ways of calibrating the control but that temp swing is too wide.

I checked the probe at 300 degrees and it was good. I even went out and checked the ground wire in the electric box. It has to be something odd, just haven't found it yet.
I could run it up to 400 and see what the probe reads, you think?

There is a chart that shows what the resistance should be at a certain temperature. It may be listed on the tech sheet inside the appliance. I'm going to check also.

The sensor is part # 316490000. 1050 ohms at 70 degrees.

Thanks PJ, I was just looking at a new probe at partsdr, but out of stock, I saw others for a little more. I would like to check the probe at higher temps and see what it does before I buy one. I got fooled on the control.
