Thank you for taking time to help me.
I see a great flame trough the burner deflector hole from outside. I just give a second try yesterday afternoon and I got similar result from the flame detection gauge. When I first light up the gas the gauge move from the "zero" position to middle of the gauge (just between white & green zones), but it doesn't move inside far green. And after knocking on the countertop the gauge move from the white/green zone to the middle of the white zone (not to the zero position). I checked outside and flame are still good (IMO).
How do I clean the burner exactly and how do I clean the thermocouple sensor? I guess the thermocouple sensor is what are connected to the red wire going inside the burner? Cause it's apparently the only wire that goes around the burner area...
I think the connection to the meter itself must be good since it sense some heat and make some move (not dead gauge), but maybe the other end of the sensor is dirty...?
