Brad E Spring Valley , MN March 12, 2019 Appliance: Frigidaire Electric Range PLES389ECG Frigidaire Range Ples389ecg: The control board had shorted out and wouldn't heat the oven efficiently. How to replace Controller. Swapped out the board. I chose not to buy the new face plate this time. When I applied the face plate on the board it was slightly misaligned.This caused a F11 error code. Taking it apart and redoing it seems to have fixed the stuck button problem. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
