Well I guess I found the problem. When I removed the three screws, which also acts like the on/off switch for the ice maker, I found a nice round black mark on the inside wall of its compartment. There is also a nce black mark on the sensor board, which to me indicated that some how this shorted out. Any nice guess on how much one of these sensor boards will cost? I will try to replace tis 1st to see if this fixes the problem.

Yes it looks like anyplace I look, the sensor board set is over $60, but if you want the ice maker to work, it is a cheap fix. You can jumper the wires to test it, but without the sensor boards the IM will never stop running, and will not know when the door was opened (safety feature) so I would not consider it a permanent fix. I have replaced plenty of these boards, $124 for the part and $137 for labor. It's up to you. Be careful which ever way you go, voltage hurts.

Glad to here you have ice now. As for the slow water, the only parts common to the dispenser and the IM are the line to and from the filter and the valve assembly itself. I would not suspect a buildup inside the system because really there is nothing to build up to. You said you removed the filter and nothing changed, so I am guessing you ran the dispenser with the filter in bypass. If having the filter out didn't improve the situation, the only possible problems would be the source connection and the valve assembly. If your water connection is to a valve on your wall, that is probably OK, but if you are using a pierce valve, that is most likely your problem. If those are OK, the valve is next. You can make small adjustments to your IM by taking the module cover off and look for a little while plastic screw sticking out on the right side. This is the fill adjustment and can give you some (not much) adjustment to the length of time the IM fill valve is turned on. But if you are getting slow water at the dispenser, I would check out the inlet and valve.
