We also have a Frigidaire stove oven issue. The error code 10. I watched how-to videos to determine what it could be and ordered the oven sensor which turns out is not the cause. Now after spending money on a part that is of no use, it turns out the control board is the cause which has cost of over $200.00 . My frigidaire gallery stove is only 5 year old and the cost if I go with a repair, is over 60% of the cost of the stove when I bought only 5 years ago. It appears I can't return the part although it appears you can unless you tried it. How does one know unless it's tried. I learned my lessen from this. Just call in a pro locally to get it repaired. Another lesson is that the appliances that are being built today will not outlive the appliance they replace from the past. The stove this one replaced was in duty for over 25 years. The same thing with the refrigerator and dishwasher.
