Hello John, I'm sorry but if the part number ever crosses, even if the manufacturer of the part crosses it, our system will say it is not compatible. The compatibility tool should be disregarded at this time with our apologies.

Ronald, Unfortunately with the cooktop being discontinued there is no suitable replacement that would be available. A ceran top would need to be the correct one that the unit calls for due to placement of the burners.

Jared for Model Number lre3021st

While doing Christmas baking, we had turned the left front burner off for about a minute, then went to turn it back on but it wouldn't come on. Pushed the button and the two dashes come on, but can't set temp. The button to select between sizes works, but neither left burners work. When starting right burners, I can hear the relay pop, I don't hear this on the left side, as they don't start. Proper voltage is supplied to range. Oven works fine.
