Craft ICEMAKER Software Update
Many Craft Icemaker replacements require a Software Update to be performed. If you are unsure if your model requires a software update, look for service bulletins listed for your specific model. To do this you will need to use GSFS or LGTA App. The Service bulletins are: CNZ202200380-01, CNZ202200379-01, CNZ202200378-01
Special Note:
To perform the Software Update you will be using the same jig that you use for Compressor Software Updates. Make sure your Jig has been updated with Software Version (8.14) or higher.
You need to be sure that you locate the correct connector on the Main PCB to plug the jig into to perform the software update. There are typically 2 unused connectors on the Main PCB.
You are probably familiar with the compressor connector, that is not what we want to use for the Craft Icemaker software update.
Locate the unused connecter on the board furthest away from the compressor connector. It is typically a 7-Pin Connector as pictured in the 2 examples below…
Caution: Make sure and unplug the refrigerator from the wall or disconnect power to the unit before attempting to update the software. Failure to do this can cause damage to the PCB and Jig.
You will be using the RED connector that came with the software update jig when you first purchased the jig. ONLY the RED connector should be used.
The Red connector of the jig only has 5 pins. The unused connector on the Main PCB will typically have 7 Pins. But no worries! You can still connect and update the software.
Locate Pin 1 on the PCB connector. It will be marked with a white arrow as shown below:
Align the Purple Wire of the RED Jig connector with Pin 1 on the Main PCB connector that you just identified.
Note: You may feel resistance when trying to plug the 5 Pin Jig Connector to the Main PCB, this is ok, it will go with a little extra force.
The full connection will look like this:
All that is left to do is make sure the Dip Switches are in the proper position on the Jig and you are ready to begin the software update. Switch 1&4 Down, Switch 2&3 Up as shown below:
- Power on the Jig. Power Indicator should illuminate Red.
- Check the Software Version making sure it is 8.14 or higher.
- Press the Advance Button. (You may have to press the Advance Button 4 or more times to advance through all the screens and there will be beeps while doing this. Keep pressing the button until you see the Downloading Progress start to increase. Once at 100% you should get an “Upgrade Complete” message).
- Power off the Jig, disconnect from the Main PCB and you have completed the Craft Icemaker Software Update.
should the fridge be plugged in??? the service guide PDF says to unplug it or the jig and board may me damaged. NO mention of that here. I updated it just now with the unit unplugged. I guess I’ll wait to get a callback from the customer to find out since techline was NO help
Good catch Chris.
Yes, power to the refrigerator should be disconnected before updating software. This has been added to the article under Step 3. Thank you for the comment.
