We have not yet installed the AppliancePartsPros spark module. After taking the stove top off *, we determined that the issue might be the spark module so ordered that from you. By the time it came, the stove burners were lighting again (poltergeist?) so we decided to wait to see if the problem recurred. However, we are grateful as the repair person we called in (who charged even though he did nothing) had told us that the stove was "old" and the parts were no longer available so we should just replace the stove. We did not want to do that so at that point we started looking for the manual and parts on line. We eventually found your site.
* I entered the time we think the repair will take as we have not done it yet. However, the diagnosis did take time as taking the stove top off was difficult as the screws had deteriorated. If that were not the case, our tool list below would have been just a screwdriver and the diagnosis much shorter. We anticipate replacing the spark module.
