LG Fridge Freezer display has CF error code

LG dispenser display on a Fridge Freezer has ER CF displayed on it. Have tried a 5min power reset. Reverts back to CF code minutes after power up.
Fidge and Freezer seem to be working fine although water from the dispenser may be a little warmer than usual? The fan may be a little quieter than usual. (You don't really pay too much attention to those things until somethings wrong).

    Thanks for coming back to me so quickly.

    The model no. is GR-L207DTUA.

    It's a side by side type model rather than over/under.

    Thanks anyway. I'm actually in New Zealand.

    I'm sorry, but the closest I could find was a model GR-L207 and that does not have numeric display. (only twin 5 bar vertical indicator lights) I'm taking a shot that this is a non- USA sold product (Canada maybe?) and I don't have access to all those, even though I'm only a couple hundred miles from the Canadian boarder.

    Perhaps you will have to check LG's web site for a service provider in your area.

    I did not find a ER CF code for a model LRFC21755. Could you check your model number again? Get it from the sticker inside the refrigerator section.

Turns out a CF ER is a Compressor Fan problem.
Had a look and the fan was not turning, although it spins freely. Apparently it's a 3 phase 12v fan. I was able to get a resistance measurement across it but didn't know what to expect.
This also explains why it seemed a bit quieter and why the water is a bit warmer sometimes. The valve for the water dispenser is right beside the fan and it's getting pretty hot in there at the moment.

I have an LG fridge display giving me ER F1 code. i can unplug the fridge and plug it back in and the display resets for about 2 minutes and the the code comes back?


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.

LG GR-B206GTQA Fridge Freezer ER CF Error Code


The fan is almost certainly run by a sensor in the condenser. If it doesn't get hot enough, the fan doesn't run. Sounds like short of gas. Try wiring the fan to the compressor live and see if it runs all the time then.

If the unit was just installed you would call for service. Error Code Er CF -The unit will receive signals from the BLDC fan motor in the freezer compartment during normal operation. If more than 65 seconds pass without a signal from the fan motor, an "Er CF" error message will be displayed. The Cooling Motor Error is usually an indication of a faulty fan motor or loose leads. Customer service should be contacted immediately. IF you have any further questions message me back Thanks Rick

Westinghouse Model WSE6070WB*5 Error code: Cn Er


I recently had this message on my Westinghouse fridge. The CN and ER message stands for Connection Error. This is due to a power surge.
I suggest you disconnect the power cord from the powerpoint and switch off for 5 minutes.
When connecting, if you have a double power point use the other head as the initial one may be faulty and this may have caused the power surge.
Hopefully this will fix the CN ER message to disappear.

Digital display on LG fridge just keeps cycling options. Showed "ER" error. Any ideas on how to get it to stop? The freezer is still cold but the refrigertor isn't cold at all


Hello sewing6
Welcome,


You said,

Try turning the fridge and the freezer off at the controls.
Then turning off the breaker for the fridge for 5 minutes .
then turn the breaker back on and restart the fridge and freezer!
This should reset the system and solve your problem.
let me know how it goes.

Thank You,
Huuum
Please remember to leave a rating! Hopefully a "solved "one.

LG LRFD25850ST gives ER CO code on door


There is a communications error between the control board and the display board.  Check the connector located on the top hinge cover.  Remove the hinge cover and check to make sure the connector is tightly secured.
