How to Troubleshoot & Replace Frigidaire AP6041423 / 5304508269 Gas Range Spark Module

I removed a few screw's from the front of the stove and pulled the top cover off the burners. The igniter module was on the left, just under the cover. I swapped a few wires around to verify the fault was indeed the igniter module. Indeed it was. I put the stove back together. The part number on the module didn't match anything online, but I found a site that said this module had been replaced with a similar part number. So that's the one I ordered. The new module arrived in 2 days. I took the stove apart, replaced the module, and put the stove back together. All of my burners ignite now. The wife is so happy. My job is done. 

I disassembled the stove top, inspected the ceramic ignitor sleeve for cracks, inspected the lead wire for possible arc spots, and sanded all the metal burner parts to be sure there was a good ground, but still only had an intermittent spark. I then swapped the lead wire from a working ignitor and got a good spark, which indicated the problem was with the spark module. Sears trouble shoot guide was no help. Found AppliancePartsPros with on line search. Very helpful on line chat and Robin verified that the Frigidare spark module is identical to Kenmore so placed order. Used lowest cost shipping, but part still came in 2 days. Required about 15 minutes to disassemble the stove top and swap spark modules which corrected the problem. I do like the videos that APP has on line, but realize they cannot possibly show all models. The video showed the spark module on the stove back (which would require pulling the stove out in the floor) while my spark module was on the top (which only required removal of the stove burners and pan). This replacement would have taken me a lot longer to locate the spark module if I had not already taken the stove top apart for diagnosis. Perhaps there should be a chart by module number to give spark module location to help others. 

I replaced the spark module as well as the wiring harness. I think it was the spark module that was the main culprit, but decided to order and replace both items because I did not want to find out it was the other one and have to wait 2 more days for the part. Now all 5 burners spark reliably, and seemingly faster. It was a slower tick-tick-tick sound prior to replacing the spark module. After installing the new module, the spark is brighter and faster. The spark module is physically different, so they must have upgraded the working circuitry compared to the OEM part. 

Repair went fine. The only problem was finding the location of the part. The videos showed it in the back or top of the appliance but it was in fact under the main top which was referenced in a forum. Again the problem was removal of the top. The model I have required the removal of the burned covers as expected but the top was not held on by clips but rather two screws in the front that required the removal of the knobs and nob front plate. After getting the top off it was just a matter of swapping the wires and screwing everything back together. 

Replaced the distribution block. This made everything ignitor spark very well. 

Replaced spark module in stove. 

Ordered a spark module from appliance parts pro and watched video from appliance parts on how to replace the spark module all went well however one of the tabs that attaches the module to the stove was broken and I had to glue it 

Replaced the ignitor module in the top back of the stove. It was very easy to replace. Just be sure to move the wires one at a time to make sure they attach to the right connections. Also, be sure to unplug the power and turn the gas valves off before repairing. 

TOOK THE TOP OFF OF THE STOVE. LOCATED THE SPARK MODULE AND REPLACED IT WITH THE NEW MODULE. THAT'S IT! 

I verified that the electronic control module was the culprit by switching wires from a working burner to those that would not light. Then I ordered the replacement ECM and swapped it out. Very easy job!
