Ice despenser door not opening

Make sure doors are always closed properly. Unclog the drain pipe. Be careful not to break the heater glass. Check the temperature settings. maybe it is at full for both sections.

Air Dryer, dull end of a butter knife...
Apply mild to low heat to the ice door area using the blow dryer. This should get the door open.

Once the door is open you will probably see a back up of ice build up, or even backed up ice cubes that clogged and froze coming down to the ice cube container.

Chip away at the ice cubes, then slowly defrost the ice using the blow dryer. Once the built up ice is melted away, dry everything up with a paper towel or towel.

Ice makers are probably the number one issues with ANY refrigerator. No need to replace them, just maintain them
every couple of months making sure you don't have a lot of ice build up

Is ice in depenser? is despenser blocked? Sometimes a few cubes get too big and block it open.. becareful with your fingers. If all this checks out, then check all connections.

Sounds like the optics are bad part # 4389102 this model(if we have the right model#)has two optics boards one receiver one emitter on either side of the door opening which shoot a beam from one to the other through the opening in each side of the bin,as long as nothing blocks that beam and the freezer is cold enough to chill the thermostat to temp in the icemaker,then it should be dumping ice.

It is probably frozen in place. The old ice tray bend and spils in the Ice Bin and eventually leaks out that door. Have you changed the ice tray with the update? This might fix your problem. Do you know if the door has illumination for the buttons? Mine doesn't and I think there should be somethng cause it is hard to read the buttons in the dark.

Check to make sure the dispenser door is closing all the way and I mean ALL the way.
GE has had issues with the solenoid rusting out on those units and not letting the door close all the way.

It sounds like your defrost controller has gone bad. I have an LFC25760 and had ice build up in the bottom of the freezer such that water would start leaking onto the floor. The ice build up in the bottom of the freezer was due to a failing/bad defrost controller. Behind the back white wall in the freezer compartment exists the cooling fins along with a heating element underneath. Due to moisture that comes into the freezer from opening it, frost/ice builds up on the cooling fins. Thus the defrost controller turns on the heating element to melt the ice/frost off of the fins which then drips into a metal pan which channels the water to a drain hole which drops into the drip pan underneath the fridge next to the fan. The problem is that the defrost controller doesn't keep the heating element on long enough or the cooling cycle comes on too soon thereby freezing the water and plugging up the drain. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.

Check to see if your drain tube is clear. Sometimes it freezes up at the base of the rear cover in these bottom freezers. Causing an ice dam.

Flap closes under spring pressure and may not be closing fully causing ice/snow build up . Bend the spring to adjust the tension and lubricate with a little vaseline

will it still dispense the whole cube?theres a brass rod under yourice bucket, remove bucket and check that rod, should be spring loaded and have a little bit of action(youll see it move a flap in front of bucket as its twisted, if so make sure the bucket is being reinstlled correctly, try the dispensor w/o the bucket installed at all, open the door trip the switch with one hand and depress the plunger for both crushed and cubed and check for the motor to turn
