Our fridge is 4 yrs old and the ice maker quit. I tried a hair dryer on the water tube in freezer with no luck.We still get water out of the water dispencer but the pressure seems a little weak to me. I pulled out the fridge and seem to have good pressure coming in from the pipes when i turn the valve on.I pulled the (4389177) filter valve and disconnected the tubes coming from the filter and there was a little water.We just put a new water filter in about 2 weeks ago. I am thinking that either the Filter valve assy is bad or the part# 6266653 module assy inside the freezer is bad. If the filter is bad is it just a matter if disconnecting the tubes and plugs? or more to it.It seems like it would be about a 10-20 minute job.Thanks for your help in advance.

I pushed in the flap opened the flap by the ice maker so the light in the freezer went off,and the flap on the left side of the fridge and the red led light pulsed/flashed on for a second and off for a second for the 20-30 seconds i monitored it

According to your replies the optics are not stable and very likely are bad.

Remove the ice maker and check for 120VAC between the black and white wires at the plug.

Remove the wire shield screw from the bottom of the ice maker.

From the rear of the ice maker, lift the top of the wire shield slightly and pull it
back to release it from the ice maker. Press up on the two retaining clips (one on each side) at the bottom of the ice maker tracks with a fingernail of each hand, pull the ice maker forward, and remove it.

Unplug the wiring harness connector from the ice maker.

I pulled the ice maker and tested the wires 3 times and each time the reading was 108.8. Sorry for the delayed reply i was out of town for a bit.
Thanks
