The oven temperature was way off below 300 degrees, but correct at higher temperatures. A new temperature probe solved the problem. Replacing the probe was very simple just like the video, but the connector did not match up as noted as a possibility in the instructions. Rather than cut off both connector and somehow replace them, I was able to remove the plastic housing from the new probe using a jewelers screwdriver to release the one way plastic tabs. I inserted the probe connector flat pins fit into the stove connecter round pin holes which fit snugly. I insulated them with heat shrink tubing which helped support the somewhat fragile flat probe connector pins against bending.
