Ice maker not making ice

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.

Make sure the ice maker "on-off" switch on the right side is in "on" position. Open the freezer door, press in the emitter flapper door (on the left side) to unblock the optics beam and view the diagnostics "status" LED on the right side. Post the results.

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

I went back an hour later closed the flap on the lfet and the red light next to the on/off switch just stayed on

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.

Is that easy to get out. Just the bolts inside the freezer compartment?

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.

Thank you i will try it and post the results

I probed it and it came back with 108. When i pulled the cover off to get at the n and l i did notice the white gear was snapped off at the base and when i looked at it there was black marks at the end of one of the copper pieces on the gear.

one other thing. When i search for the part number you gave me, i see alot of searches coming back with part 2198597. Are they compatible or is one a replacement number for the other one.

Thanks

ok thnaks i just wanted to make sure they are the same part.
