Error Code Er 1F on new Kenmore Elite Bottom

The ER 1F code usually means that there is a problem with the ice compartment fan, the ice maker motor or one of the control boards (the one for the ice maker or the main control unit). You can try resetting the refrigerator by leaving it unplugged for a day. Next check for ice build up on the fan that is blocking it from turning. Usually, if the fan hasn't been turning, you will have to at minimum replace the motor. It will burn out trying to force the fan to turn.

Sears Parts Direct has a diagram of the LFX23961SW case parts here: http://www.searspartsdirect.com/lg-refrigerator-parts/model-LFX23961SW/3204/0161000/K0810254/00001.html . The fan motor is part 405G.

I hope this helps.

Maybe this will help. i would check fan first and see if ice has built up in fan.

You are probably seeing the Er IF error code that indicates a problem with the ice compartment fan.

The Er IF error code indicates that the main control board detects that the ice compartment cooling fan is not working. This will cause a lack of cooling in the ice compartment and will normally result in no ice production. This is something that a service technician will usually need to correct. If you are advanced in technical skills, you may be able to correct this problem yourself. It will require the removal of the inside back panel of the freezer compartment. This is not an easy task. I recommend that you review the procedure for this task that is shown in the image below. Make sure that you are able to safely perform the tasks described before proceeding with this repair. Unplug the refrigerator to disconnect electrical power before accessing internal components. Once you access the ice fan, you may find excessive frost in this area and on the evaporator that could be causing your cooling problem and fan problem. If you defrost this area, you may find that you do not need to replace parts. If you find no excessive frost or the Er IF error code resumes after removing any frost then you will likely need to replace the ice fan. You can order this part here.

This is an error code for the icemaker fan motor.
If the control does not see a signal coming back from the fan motor you will get this error code.
Please see the image below from the service manual that explains the ER IF error code.

The ER IF code indicates a failure of the icing fan.

You may notice slower ice production but the other fans should be okay.

You can select the ultra ice option and see if the fan toggles on.

The fan or the control is bad.

It is ER IF and indicates that the ice maker fan is not working. The fan is probably frozen. If you can remove the fan duct and housing at the back of the freezer you may be able to defrost the ice in the fan enclosure. The fan may have frozen because of hight humidity or because the defrost cycle is not working.
