Jepson O Freeville , NY April 20, 2016 Lg electric oven would'nt go above 220 degrees and found no power going to lower element and top element would cycle on & off First tried replaceing the oven temp. sensor, (the cheapest), no luck. Then started pokeing around and found no power was going to lower element. Replaced the Oven PCB and it did the trick. Oven works like a champ now. 14 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
