I had an issue with front burners not sparking enough and thereby not igniting the gas.
I purchased two igniters, replaced them, and this only fixed one of the burners, the other front one wouldn't spark (front right). I then decided to switch around one of the working burner assemblies (the rear one) with the one that wasn't igniting (front right). Once switched, the (front right) burner assembly worked fine at the rear position, and the previously working burner (rear) now at the front position would rarely spark if at all.
The igniter switch switch seems to be fine, since all the other burners start sparking, except for the front right when I turn it on.
I think it may be the ignition module, which I just ordered.
Please let me know what part I should now replace. I could also use some instructions on how to replace the part at issue (if it is the module). I did take a loot at the exploded (disassembled) diagrams of my oven posted on this site.
Thank you for your help.

This is so similiar to my problem that I thought that I had posted it. WE have bought a spark igniter electrode for our Bosch Gas Cooktop but need some directions on how to replace it. Did you find a site for instructions? MaStone Originally Posted by: vv220  I had an issue with front burners not sparking enough and thereby not igniting the gas.

When you order the parts, a lot of these sites will have scanned pages from service manuals showing exploded views of the oven. Mine happened to be in the back, at that point it was a matter of removing a heat shield and disconnecting the wires. Be careful with the contacts and turn off the power. I doubt you'll find step by step instructions, best bet is to get the exploded view and figure it out how to remove/replace.

Unscrew the three screws holding each base ring. Very likely most of them are rusted in, so you will need to drill out such screws. While doing that try not to damage the burners. Remove all knobs and carefully pull up the glass top. The igniter is attached to the burner. If you do not feel comfortable to do it yourself then hire a pro to do it for you. Here are the breakdown diagrams and Replacement parts for Bosch NHT922 | AppliancePartsPros.comGene.

How do you disconnect the spark igniter electrode from the burner? Do you have to disconnect the gas line and remove the burner?
Thanks.

Gene, we have replaced the spark igniter devices on the front two elements which were the problem..parts 421156. The metal spark piece that sticks out of the device is shorter than the original.*?
anyway, the front two light but spark non stop. Can you pull those wire pieces further out or how can we get that sparking to stop??
Thanks.
MaStone
