Already have manual, Thanks!
does the igniter even try to spark?
It does, I can get it to stay lit if I press and hold the Push-button igniter on the front panel.
can you light it manually? I know you said "seems like gas isn't getting to there" but have you verified that? How?
I was wrong, gas is there. Does this sound like a thermocouple?
If no gas (suddenly, after working ok) then maybe gas shutoff solenoid?
Controller board?
Need to step through troubleshooting steps, and verify
12V
Gas
igniter
thermocouple
checking gas pressure would not be next in my steps - I would verify presence of gas in ANY pressure is getting to the burner.
If yes, then MAYBE check pressure but a number of things still to check
The fridge needs:
12V to open the gas solenoid
12V to ignitor to spark
gas to burner (orifice not plugged - spiders love to build webs there)
thermocouple to sense flame
controller board holds open the gas solenoid once flame is sensed
controller board also does a bunch of the sequencing of the above.
