Ice maker on refrigerator not working

[Dipdog]

The ice maker on my whirlpool ED22TEXHW00 is not working. When I jump T and H, it runs through a complete cycle, but water does not come out of the fill tube at the end of the cycle. But, when I jump V and L, water does come out of the fill tube. If I pour water in manually, water freezes, auger spins, heat coil heats, ice pops out. But no water out the full tube. I would think it was a bad water valve, but water comes out just fine when I jump V and L. I thought maybe low pressure/bad filter, but same thing happens with the filter removed. I thought the IM module might be bad, so I replaced the entire ice maker assembly, but it's still doing the same thing!
Any suggestions?

The only thing left is the water inlet valve.  When the icemaker cycles, the power going to the valve is in series with the mold heater.  There is a voltage drop of about 12 to 14 volts.  It's possible the valve will work with 120vac. but not 106vac.

When you jump V and L, does that bypass the mold heater (120vac)?

Yes.

ok... sigh.  it's an expensive part, wish there was a way to test that idea first.  that seems to be the most reasonable explanation I've heard, though.  I haven't tried to actually read the schematic for the IM module, but it sounds like the only difference between connecting to the water valve by jumping V-L and connecting to the water valve automatically at the end of a cycle, is the voltage drop through the heat coil.  I'll give it a shot, thx!

hey, actually, can I ask you just one other question? 
I hadn't mentioned this, but when I first noticed the problem, the first things I realized were that the water filter hadn't been changed in a while, and there was an ice plug in the water delivery line.  Since then, while I've been troubleshooting this, I've left the ice maker on, it spins but no water at the end of the cycle (I've removed the water filter so that it's under full pressure), but I've continued to get some ice plugs in the delivery line that I've had to clear out every so often.
So, if the water valve mechanically went bad because the water filter hadn't been changed (which would explain dribbling water and ice plugs), would it be possible that the extra voltage when I jump V and L would be enough to open a mechanically (as oppposed to electrically) bad valve (or is that what you were suggesting)?

sorry I never got back to this.  just wanted to post the results in case it helps anyone else.  I purchased the oem water valve used on ebay, got a pretty good deal on it.  and it worked perfect; there was nothing wrong with the icemaker assembly or the module, it was just the water valve that needed replaced.  thanks again for your help!

Thanks for the update. Ice blocking the fill tube means a drippy water valve. Forming a stalagmite. Seen it.
