    Angry GE icemaker overfilling when using water dispenser

    hi,

    i have a GE side by side frig model TFX22ZPBBWW. the problem is when i use the water dispenser the ice maker overfills and leaks. the ice maker is level. i just bought a brand new ice maker WR30X0327 to replace the problem i had with the ice maker leaking when making ice. maybe that was a mistake because i put in the old ice maker and it too was overfilling and leaking when i used the water dispenser. so i suspect the problem isn't with the ice maker unless the new one has the same problem but, at least the new ice maker isn't leaking when making ice anymore. now i would like to fix the water dispenser/ice maker problem.

    the one thing i noticed both ice makers doing and i'm not sure if this is by design but when i press the water dispenser the water enters the ice maker the same way it does as if it was making ice! ie through the tube above the ice maker dropping into the top of the ice maker. the ice maker overfills and leaks but, i'm also getting water from the water dispenser.

    just wanted to give you and update. i purchased a new relay harness and installed it today. but, water still comes out from the water line that goes to the ice maker when i request water from the water dispenser. what should i do now??

    i appreciate any help you can offer.

    Without a wiring diagram, difficult to give any further guidance. There should be a diagram behind the grille beneath the doors - can you scan and post it?

    Have you replaced the relay and harness assy, reference # 797 in this breakdown?? Something is shorted, feeding both sides of the fill valve when you press the water disp lever...

    Is there a board in the disp area that could be shorted, feeding both valves at the same time??/

    i did look at the dispenser area. and there was a board i only saw a corner of it because i didn't want to take the dispenser apart any further but, i did see what appeared to be computer electronic board. how can i tell if that is causing the problem?

    Looking at your diagram, there's no relationship between the wiring of the I/M and that of the water dispenser. Something has to be shorted somewhere, I'd take a long, hard look at that 12 pin "harness connector".

    Default 12 pin harness

    hi mad mac,

    by 12 pin harness are you refering to harness relay item #797 as noted above?

    what do you think about the idea of replacing the control board in the water dispenser?

    in the mean time i will check relay harness i replaced with the wiring diagram.

    The control board in the door has nothing to do with the icemaker water valve. There has to be something connecting the power for the water dispenser valve and the power for the icemaker water valve. As you've already replaced the relay and harness assembly, I'd rule that out, although stranger things have happened.

    The 12 pin "harness connector" is shown on the left hand drawing you posted above, just above the compressor. I can't locate it on any of the parts breakdowns online, you're going to have to look for it.
