To replace the spark module on a Viking VGSU161 gas cooktop, follow these steps:
1. Turn off the gas supply and unplug the cooktop from the power source to ensure safety.
2. Remove the grates, burner caps, and burner heads from the cooktop to access the spark module.
3. Locate the spark module, usually underneath the cooktop surface near the burner valves.
4. Disconnect the wires from the old spark module carefully. Take note of their positions to reconnect them correctly later.
5. Unscrew and remove the old spark module from its mounting bracket.
6. Install the new spark module onto the mounting bracket and secure it with screws.
7. Reconnect the wires to the new spark module, ensuring they match the original positions.
8. Reassemble the cooktop components and restore the gas and power supply.
Always exercise caution when working with gas appliances, and consider seeking professional assistance if you're unsure about the process.
