PROBLEM - MY LG RANGE (LRE3091ST) STARTED TO HEAT BUT WOULD NOT GET TO THE FULL TEMP, IT SHUT OFF & GAVE US AN F-11 CODE. I REMOVED THE BAKE HEATING ELEMENT & OVEN SENSOR TO SEE IF THEY WERE WORKING PROPERLY. (YOUTUBE CAN SHOW YOU HOW TO DO THIS) THEY WERE WORKING FINE. SO I ORDERED THE CONTROL BOARD. MY HUSBAND REPLACED IT VERY QUICKLY& THE OVEN IS HEATING UP BETTER THAN BEFORE! GREAT PRICE - VERY FAST SHIPPING!
