Product review (5 stars): This is not necessary but I would recommend it to avoid frustration
Very straight forward removal and replacement to install.  Used on Viking VGRT5366BSS:  Viking 6 burner gas range top.  Burners would not ignite even thought the burner sparkers were "clicking".  Turn off electricity to the unit at the breaker box.  Then remove a total of 10 screws to access the module.  Simple removal of the range top front bar and front face plate after pulling knobs off and you have access to the module.  I chose to unscrew the module from its mounting plate to make swapping of the spade connectors a little easier.  This is not necessary but I would recommend it to avoid frustration.  Net/Net - this is easy fix for almost any novice.
