The phototransistor is mounted in all Viking B16 and 9990
Fits all Viking burners.
When changing the fire guard, install the cables according to the color first.
If the burner skips “Ignition”,
and goes directly to "Startup and Normal Fire", change the cables to the fire guard.
Try illuminating the phototransistor with a cigarette lighter, hold it a few cm away
because the phototransistor is heat sensitive.
It has to be the right color temperature, so LED lights or fluorescent lights won't work.
A sign (@ or a "dot") should appear when it is illuminated.
