Icemaker Locks/Freezes up

You can buy a little steamer at the store and use it to defrost small areas. usually it's the fill tube that freezes, and you can hit just it with the handheld steamer. Lots of times however, this model will create a large ice flow below the glass shelf behind the upper basket and icemaker. this is usually caused by a bad drain trough heater. the only way to defrost this is to turn the unit off for 2 days and put towels down inside it and underneath it to catch the water as the ice melts.

Possibly there is a 2 part problem you are experiencing. 1)That vibration i dont think is the ice maker. It is your evaporator motor. 2)The fact that the icemaker is not forming the blocks nicely could be because the freezer setting could be set a little to low. The freezer temp. is what freezes the ice maker blocks. You may want to play it safe and do a 12 hour defrost which may be the reason why the vibration is heard.and reduced freezer temp.

Sometimes icemakers get all frozen up, such that the motor cannot turn to eject the ice. Also, in some cases the water supply line freezes up, although that does not sound like your problem.

Try leaving the freezer open to defrost it manually and see if it starts working by itself. Also, the icemaker motors can and do fail. In some cases you smell an acrid burning smell when the motor fails.

Check defrost heater that goes into drain tube. When the drain freezes ;the defrost water spills into the icemaker.

Pour about 1/2 cup of water into icemaker . If it freezes and dumps , the water valve is bad ( where the wall water line connects to the fridge ) . If it freezes and does not dump and the ice stays in the icemaker , replace the icemaker . Also check the fill tube ( the tube going from the freezer wall to the icemaker itself ) to see if it has frozen closed . If it has , the water valve is not closing completely , and letting a drop thru and freezing in the tube . Also an indication of a bad water valve .

are you sure the water comming from the icemaker or the defrost drain line clogged

so what the problem exactly?

Sounds like you have a fan problem or more likely a defrost problem( timer motor or heater element) Most likely the defrost timer!

it is probably a faulty water valve that slowly leaks water up to the icemaker and freezing. sometimes it will freeze inside the fill tube and block the water supply completely.

• if you already checked this and think it is a different problem then let me know, i will help you figure it out.

The ice maker won't work if the freezer is warmer than 17 degrees so that's not an issue till you get the freezer cold again. I would guess that your unit is stuck in the defrost cycle. This could be the defrost timer failing. See if you can find the defrost timer in your unit and advance it by hand if possible. http://www.partselect.com/PartSearchResults.aspx?modelnum=jcd2295hes&mfgmodelnum=&fkmfgid=1&hint=defrost
