Ice maker door frosts over - turning to ice. I have to chip it off - but it returns if icemaker is on

The error code 1F on an LG refrigerator indicates a problem with the ice maker fan. The most common cause of this error code is frost or ice buildup around the fan. If you have disconnected the water line to the ice maker, then the most likely cause of the error code is frost or ice buildup. To fix the error code 1F, you will need to defrost the ice maker fan. This can be done by following these steps: Unplug the refrigerator or turn off the circuit breaker that powers the refrigerator. Remove all food and drawers from the freezer compartment. Open the freezer door and allow the ice to melt. Once the ice has melted, use a hair dryer or heat gun to melt any remaining frost or ice around the ice maker fan. Wipe away any moisture with a clean cloth. Reassemble the freezer compartment and plug in the refrigerator or turn on the circuit breaker. If the error code 1F persists after defrosting the ice maker fan, then there may be a problem with the ice maker fan motor or the control board. In this case, it is best to contact a qualified technician for assistance. Here are some tips to prevent the error code 1F from coming back: Keep the freezer door closed as much as possible to minimize air circulation. Defrost the refrigerator regularly, even if the ice maker is not in use. Clean the ice maker coils regularly to prevent frost buildup. If you live in an area with hard water, consider using a water softener to reduce the amount of minerals in the water that can contribute to frost buildup. By following these tips, you can help to prevent the error code 1F from coming back and keep your refrigerator ice maker working properly.

Freezer temp has to be 10 degrees or less for ice maker to work. Door gaskets ok and not leaking moist air into freezer? Defrost mechanism working?

is water supply ok? leak around freezer door, fix/replace freezer door gasket

I need you to confirm your model number. Is MZD2665HE correct? The problem is very likely a broken 12565502 Dispenser Door Spring or more providing you have the correct model number. There may be a kit if the model number is different.Thanks, John Tripp Appliance 911

Hi and welcome to FixYa, I am Kelly.

Often when ice-makers stop working the real problem is that the freezer is not cold enough (It must be 14-16F for the icemaker thermostat to cycle) Check for signs of ice or substantial frost in the back of the unit / evaporator coil area. If you have ice / frost in this area you should do a manual defrost by unplugging the unit and directing an external fan into the freezer compartment for about 2 hours while it makes a water mess that will need to be tended too. Once the 2 hour thawing is complete wipe up the excess water and return the unit to normal service. If the problem was caused by excess ice it will operate normall for 2 - 3 days before ice production slows or stops totally. Should the manual defrosting correct the icemaker problem you most likely have and automatic defrost problem in the form of a problem with one of these 3 components:
1. Defrost control
2. Defrost heating element
3. Defrost thermostat

Having said all of that... You can use this manual to check out your icemaker:

Make sure to test the coils on the inlet water valve for continuity. If one of the coils is open *** must be replaced. The inlet water valve is NOT repairable.

Your water valve can be found here:

Here is another link on how to test out the icemaker:
http://www.american-appliance.com/catalog/newsdesk_info.php?newsPath=12&newsdesk_id=34

The ice-maker thermostat must be at or belw 16 F for the above tests to work.
NOTE the freezer door LIGHT switch must be taped down also.

Before you get too deep into troubleshooting checkout the freezer door light switch first. If the switch is bad the freezer compartment light will not work and the ice-maker also will not work.

Greetings,
there should be a way to shut it off totally...check to see if any water is frozen in the icemaker fill tube coming into the icemaker..if so, use a hair drier to melt ice for temp service. if there is ice build up in tube...you will need a new solenoid....be careful, it may not be solenoid...sometimes its the icemaker itself...

if the ice is coming out then this shouldnt be a problem, warm air from the kitchen is condensating when the icemaker is activated,

Who replaced a motor in an ice maker? There are no motors to replace. Demand your money back and buy a new ice maker at your local appliance parts store or on line.

have you felt water in the ice maker or ice cubes thats the only way you know for sure.. just cause water in doors works doesnt mean icemaker getting water.. got different valves giving water to different places Is your freezer temp. right.. has to be right temp for icemaker to work.. check back wall in freezer make sure no frost buildup and if fan working
