Calibrate Electric Oven?

Our Frigidaire FEF336ASF oven is off by 15 to 20 degrees. If you want 350, you have to set it to 365-370. We found this out last Thanksgiving when the turkey wasn’t done on time and we have just been dealing with it since then.

Is there a way to calibrate this oven?

I tried holding bake in for a bit and never get 00. I get F1.
Same on just holding in Clear.

TIA

Here is a service manual

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

It does not look like this oven control board can be calibrated.
Check the temperature sensor if it is OK then the control board is the most likely cause.
