Didn't need to turn power off. Used flashlight and mirror. Easy to unscrew light and install new on. Previous LED bulb lasted about 5 years. Because the environment is freezing, I ordered original part number, easily found on Sears parts list. I am not sure a regular LED could survive the freezing temperature inside freezer. The high price is challenging to swallow, but the exact replacement made by Electrolux, works perfect. Sears realledy supports ALL of their product, and the website is fully loaded and user friendly. Great Job!
