Control Pad displays Er CO.

possible bad display board or control board

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.

The Er Co error code signifies a communication error between the display control board on the freezer door and the main power board on the outer back panel of the refrigerator.

Check the wiring and connections between the low voltage interface and the main high voltage board.

If you are able to unplug the refrigerator and remove the cover over the control board on the back of the refrigerator,
you can check the wiring connection on the main control board.

If this wiring connection is okay, check the wire harness connection under the hinge cover on the top of the left hand refrigerator door.
If these connections are okay, then you will need access the wire harness connection in the dispenser.

try unplugging the unit and waiting 9 minutes then plugging it back in.

er if means the ice fan is not running. it blows freezing air into the ice maker compartment from the freezer. unplug the refer for 24. these are susceptible to frost or ice forming in the blade of the fan and prevents it from spinning. unplugging it will let it thaw. ice is a big problem with this model.

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 first thing I would do is remove the panel on the back of the fridge to access the control board. It should be about half way up on the left hand side if you are looking at the back of the fridge. There should be four 1/4" screws to remove. In the middle of that board there should be a reset button. Press that button then let me know if that worked.

I have this problem also my control panel is not working. It has an Er If on the panel.
