Domestic RM2852 piezoelectric fires over and over again.
The fridge works fine on both gas and electric but I can hear the piezoelectric going off continuously on either setting. I just bought this fridge 6 months ago....

IMO there might be more going on here than just a bad board, so if it were mine, and under warranty, I would rather have a tech do it all. That way if he replaces the board and something is still wrong, he can figure it out instead of you.
My first thought that it could be a Murphy in the wiring to the board, and not the board, seems to be most unlikely, since it is a plug in from ignition module to the board, not individual wires to blade terminals.
However, it is a puzzle how the gas mode works at all if the board is bad. And then how can it still spark after there is a nice blue flame? I thought the flame sensor from the ignition module would shut off the ignition spark.
Or if that signal goes back to the board, then what use is the ignition module if it just passes voltage to/from the sparker and sensor?
Sparking while in AC mode but no flame means there is no gas. (good!) but I thought the signal to spark "went with" the signal to open the gas valve.
