just wondering if you found the problem?

Mobile tech just fixed mine for the same problem: he just cleaned everything. Good luck!

check the spark gap at the ignighter. if the gap is too wide you will not get any spark.

I have a Model #GC10A-3E

Then DC voltage flow path would be like I posted for propane.


Water heater AC is completely separate system.......120V AC direct, doesn't use circuit board and have there own set of t-stats on backside of water heater where element is.
So electric side should work unless you have 120AC issues.

2003 vintage most likely is older version of water heater (design change occurred in 2003)

12V DC comes from FUSED circuit (DC Dist Panel) to ON/OFF switch
Brown wire from on/off to 'thermal cut out' (one shot fuse) to T-stat
Brown wire from T-stat to circuit board
Red wire from circuit board to ECO
Red wire from ECO to gas valve solenoids.....then black wire to ground


What model is yours?

G10-3E or GC10A-3E OR a 4E version
