On a Kenmore Trio 78729 made by LG, open left door and push the Ultra Ice and Refrigerator button simultaneously for 5 seconds. The display will change from 0 OFF to temperature settings.

I just purchased a similar model and had the same frustration. Finally called the store and it was in DEMO mode. Open the freezer draw and hold down the Ultra Ice & Refrigerator Temp buttons simultaneously for 5 seconds. That worked for me and hope it will do the trick for you.

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.

This is an error code that pertains to the evaporator motor but could also be the main board.
If the evaporator motor is running, the main board will probably need to be replaced.
It could be a wiring problem but it's not very likely.

If the motor is not running, some voltage checks will need to be made, at the motor and board, to determine which component has failed.
These checks require a meter and can be difficult to make, even for a technician.
