Problem has been posted before but seeing no answers. While oven heats up, probe light comes on, effectively turning oven off even though no probe is inserted. Solution so far is simply cancel and try again after the probe light turns off and hope it works. Or I heat to 280 and because the probe rarely engages by that point, I then change the preheat temp to the needed level (e.g., 425). I would prefer a repair over a "fix."
