How can I open my VGSU161-6BSS unit to see the spark module pant number in order to replace it?
I need to replace the spark module of my VGSU161-6BSS but I do not know the part number. I have been told by Viking part dealers that there are two part numbers that could suit me: PA020042 and PA020048, but to be sure I have to open the unit and get the correct part number. How can I do this? Burners Bases are hard to remove!

First of all, the model number is under the cooktop bottom, and secondly, this can happen due to the burner switches got wet somehow. Best thing to do is to unplug unit for 6-12 hours, allow to dry, then re-plug unit back in, this should be enough time to dry out the burner switches.
Possible stuck burner switch or failed spark module. Unplug unit. Remove wires from burner switches at module and plug back in. If it starts sparking, replace module. If it stops, then replace switch harness.
If you can hear the clicking sound but are not getting a spark then there is probably a short in the ignition system. Check for any loose wires on the ignition system. Make sure all the wires are properly seated. Make sure the spark module is properly grounded. As far as testing the spark module it should be generating a spark of course. The problem is that the average voltage for the spark module is 15,000 VDC so actual testing of that voltage can be difficult. Is the spark erratic?(should spark evenly). An erratic spark timing is a sign of a bad spark module. Is the spark slow? Check the polarity of the electrical plug. If it is clicking evenly then it is probably arcing somewhere inside the cooktop and you just need to find out where. Also be aware that if you get water into the cooktop that can cause possible grounding of the spark module or ignition system.
Well, it happened again. I'd replaced the spark module last time around, due to spillage getting into/onto that control unit. This time around, I had one burner that just kept sparking after it was lit. Cleaning the sparking post (emitter) didn't solve the problem, but I realized that there might be contamination elsewhere in the connect. I pulled the brass rings (nuts, really) and was able to lift the the top off. I carefully removed the individual sparking wires from each burner, and examined each assembly. After cleaning some debris off the male connector for that bad burner's spark assy, and reassembling the cooktop, it worked!
Things learned: The top can lift off without having to worry about dropping the entire unit. (This probably varies by model). The emitters _and_their_connectors_ are sensitive to contaminants. This was an EASY fix! Thanks for the helpful instructions everyone!
I had the same issue and replaced the spark module myself, lots of wires and you have to make sure to label them before removal to be able to hook them back up correctly. To get to the module you need to unscrew all burners, no need to take the cover plate under the knobs. Burners remove by unscrewing center, brass nut. OEM spark module is VIKING RANGE #PA020021 U-67205-21. Go
