Hello!
I have a jandy lite 2 and it keeps turning off with an error fl 2. After cleaning and checking flame sensor I decided to give it a try and had the same error. It appears that the issue isn't with the flame sensor, but the flame channel the sensor is connected to. Of the 10 or so flame channels, each one lights except the one with the sensor.

How do I clean the flame channel gas jet to remove any sort of blockage? The damn thing looks almost impossible to remove!
