My icemaker is overfilling and cause a chunk of ice in the bottom of the maker.
My icemaker is filling up the ice trays then it refills them again right away which is causing the tray to overfill and then spill over and run into the bottom and make one big chunk. Then the cubes that are being produced are just bottom shells of hollow ice. It seems like maybe there should be a timer to slow down when the water should refill and it is off and trying to refill one right after the other. Please help. Please feel free to ask any questions that may help you understand my problem better to help fix my problem. I would greatly appreciate any advice. Thanks

Re: My icemaker is overfilling and cause a chunk of ice...
Bh, on these GE icemakers the amount of water entering the mold is controlled by temperature. There is a thermistor that sits in back by the mold. Water entering the icemaker will cause the temp. of the mold to change, effecting the resistance of the thermistor. The initial fill will activate the water valve for 5.1 seconds. After this fill there should be a 15 second delay while determining the temp of the mold. If the mold exeeds 39 degrees the fill will end and start the freeze cycle. If the temp is still below 39 degrees the control will assume there is not enough water and run the valve again for 2.5 seconds and repeat this again if the thermistor still reads below 39 degrees. Therefore Im thinking you have a thermistor problem. Im not sure if this is a serviceable part. You would have to check with GE. Catriver..post back.

What is your model number? Sounds like you may need a new icemaker. Sometimes when the icemaker motor goes bad it causes the icemaker to keep filling even though it hasn't kicked out the ice in there. Also, are you sure there isn't 2 valves on the refrigerator?
replace the ice maker . if ice cotting is bad / when in harvest all the cubes don't fall causing over fill on next cycle . . if water valve does not close all the way it can also cause over fill .. if more help is needed ( brand and model # pls ) hopr this hepled ****
1.Bad water valve located in the back bottom of refrigerator.
2. Frozen fill tube going into back of ice maker. (common problem)
3. Ice maker not cycling. Pour water into ice maker cavity until near filled.
Wait a few hours and see if it dumps.
4.In rare cases, the switch in the ice maker body fails. Ice maker will cycle but not tell water valve to refill.
Sounds like the water inlet valve to icemaker is leaking - not closing completely after filling the tray. Rare, but possible. Prove it by shutting off icemaker arm or switch. If that is the cause, the drip will continue.
If dripping stops when I/M is off, then it is ice blockage in I/M fill tube and or diverter funnel at end of ice tray. Remove I/M, clean ice from both, and re-assemble.
Replacing that valve (water supply to refrig connects to it in the back) should solve it.
Please confirm you have given the complete model number.
If the icemaker has a bail wire to control how much ice is in the bin, there is a fill switch inside the front cover of the ice maker which allows you to increase or decrease the amount of fill.
You may also have a cracked or corroded ice mold. Check by filling the icemaker with water manually, and watching to see if it drips once the initial overfill stops dripping. This would also be indicated by the ice cubes being smaller than usual.
mine was overfilling because the ice was getting stuck on the way out. So some stayed in the tray and when the water would refil, it would overfil and go over the stuk cubes. leaving it to overflow to the bottom and freeze like yours.
