My name is Peter. I am a retired field service refrigeration technician.
Ok, I am going to give you a series of things to check.
1.) Reach into the back of your ice maker. You have a fill cup and a full tube. Are they filled with ice? If so you have a frozen fill tube. You must remove the ice maker and with a hair dryer clear the tube.
To remove the ice maker:
On the left hand side there are two screws on top - loosen them. On the bottom there is one screw - remove it. There is a conduit connector in the rear - squeeze the tabs to release. Now, lift the ice maker up and pull away from the wall. If the ice maker does not lift out, loosen the top screws a little more.
2.) reach into your ice maker mold (tray) are their any ice cubes jamming the unit? Clear and lift your lever arm up and then down.
3.) Were you getting small ice cubes? And then no ice cubes? This could be a ice maker solenoid valve problem.
This component cost $165.00. You can get It for about 40% less on the internet. Part number 215197400.
Purchase locally, Cost $55.00.
4.) You will need a multi-meter to check the solenoid valve. Unplug the unit. remove the bottom cover. You have a duel solenoid valve assembly. On the right bottom is your solenoid assembly. The plastic tubing running up the wall is for your ice maker. With a multi-meter set to the lowest Ohms, disconnect the two contacts on the ice maker solenoid. On the solenoid, use your meter leads on each contact. You should get a reading of '0'. if it is good. Anything other than '0' is bad.
5.) Within your ice maker you may have a bad thermostat.
This component is $62.00.
If your ice maker solenoid valve is good, rather than try to repair your ice maker, you can purchase a ice maker locally for $110.00, or go on line and purchase one for $45.00.
Your ice maker part number is FRS22XGCD0
