My 8 year old fridge has stopped producing water and ice through the door. What could be the problem?

The solenoid has nothing to do with the crusher mechanism. Rather it delivers water to the ice tray when empty. Check that the ice door closes completely after ice is dispensed otherwise frost can build up in the crusher blades and prevent them from moving into position. Otherwise, check for a worn out part that connects to the blades and would prevent them from articulating.

The water fill tubes might be bad with your fridge and there is a problem with the water tubes too which will need to be replaced as well.

possible bad water solenoid or blocked line

Change the water filter.Here's how to do it How to Change Water Filter in Kenmore Refrigerator

hello. remove the lower front grate, at the floor level and clean the dust from under the unit. Also, check the interior bottom of the fridge and clean the "floor" being sure that the small drain hole is free of any debris. This will allow the water produced when the unit self-defrosts to travel through the fridge to the evaporation plate below and not stop in the cheese drawer. J.

LG has problems with there ice makers. if is less than a year old it is under warrenty--even if you dont have a reciept. sounds like the ice maker needs replaced. i have replaced several that were less than a year old.

the water that is frozen in the fill tube could have come from the old water valve that you replaced ,you got to get the ice out, the easiest way ,though not the fastest ,is to unplug fridge for 24 hrs . and leave the doors open to let it defrost, the plug back up and hopefully in 5 or 6 hrs you'll have ice

Have you changed the water filter. It should be located in the front loer grille of the refrigerator.

the module on the icemaker may be bad or the emitter-recever

It could be the water soleniod screen is clogged or if you have a filter clogged. Take the water line loose and check the screen first.
