Opened the box and took out the black color grates~~removed discolored grates and put the new ones on. Looks like a brand new stove and much nicer to look at as it is the first thing you see when you enter the kitchen.
unplug the oven and pull it away from the wall. looking at the oven from the back, the spark module is at the bottom on the lower left. there is a two piece sheetmetal cover over the area of the spark module. use a phillips head screwdriver to remove five screws and the covers come off. the spark module is the blue cube with four push on wire connectors. all you have to do is hold the new one next to the old one and swap one wire at a time. both were clearly marked with identical numbers and letters. really nothing to it. it took me longer to clean the back of the oven than to replace the module. the old module was eaton part number Y-54052-3. the new one is eaton part number Y-054052-34.
I had an appliance repair rep do the replacement. He made it look relatively easy. The repair man first turned off the breaker to the range and confirmed there was no power to the range. After lifting off the range top cover exposing the burner igniters, he unhooked and removed the igniters. He opened the lower oven door exposing the screws which hold the front knob plate in position. He took those out. After loosening the knob plate he was able to unscrew and raise the inside cover which exposes the wires and the spark module. My spark module was located in the front left corner area tucked a little under the knob plate. That is another reason why he had to loosen the plate. The replacement part was a universal part so he had to do a little work on the wire connectors but it only took a couple of minutes. Once he configured the wire ends, he was able to plug in the new spark module and put the top back together again. The repair man knew exactly what to do and made it look relatively easy. I did not want to tackle this problem because I did not know exactly where the spark module was since some models have them in the back of the oven and the oven has to come out from the wall. Also, the wire connections had to be worked with a little and he knew exactly how to do that. The repair man took about 45 minutes from beginning to end with most of that time spent getting to the part and putting it back together. The replacement itself took only about 10 minutes.
