The wife indicated she heard a pop sound when baking. I purchased a backing element and installed it in the oven. Tried the stove and the ERR came up again. This time I took my time and searched my stove model number and under common symptoms and solutions clicked on the "Little or no heat when baking" title under the diagrams of my range. I found that the oven probe was 34% of the time the cause of the problem and the baking element 28%. I ordered the oven probe after checking the resistance and replaced it. This time after turning the stove on it worked.
