I have near 0 continuity between the two prongs. actually (1200 ohms) is the part (8283346 ) defective ?
The resistance of the fill valve solenoid should be between 695 and 995 ohms of resistance and if you got 1200 then it is out of range and would need to be replaced.
I replaced the door seal and water is still running out the bottom of the door. What can I do next to stop the water?
You will want to check for clogged or broken spray arms that are causing the water to spray at a different angle and can cause the unit to push water out of the door.
