Hi @chrisesquivel
Here's the [document|38920|service manual] for the model.
Go to p.21 to view the procedure for how to run the diagnostic tests and check what error codes (if any) are being displayed.
The error code troubleshooting guide is from p.24→
If a part is faulty and needs to be replaced, here's a [https://www.searspartsdirect.com/model/5jck3qs4te-003204/lg-lmxs27626d-00-bottom-mount-refrigerator-parts|parts list] that is ''useful.'' When you locate the wanted part in the list you'll see that the ''manufacturer's part number'' is listed with it. Search online for the part number only, to find supplies that suit you best.
Hopefully this is of some help.
