Hi,
I have a 3 year old LRG3085ST gas range/oven with a heating problem. I set the oven to bake at 350° and it shows preheating on the display with the temp progressing upwards. The display stalls at 345° but the burner continues and the actual oven temp gets to over 450°. Then the ready chime sounds, the display says 350° but the oven is now over 450° and the display still says 350°. If I let the oven cool to 350° actual oven temp, the oven now will maintain 350°.

If I try to preheat from cold to any temp below 300° it functions normally. Also, I can preheat to 275° and after the chime sounds hit Bake 350° or anything higher and the oven temp levels off and functions properly but no chime. VERY STRANGE. I have replaced the main oven PCB, relay board and the thermistor probe. I can make the oven serviceable by doing my two step preheat but shouldn't have to. Also, there is no power to the convection motor at any temp. Any ideas?

Thanks,
Denis
