Stephen D Lake Jackson , TX May 21, 2021 Appliance: LG Refrigerator LFX31945ST Lg Refrigerator Lfx31945st: Lfx31945st door handle screw missing. How to replace Set Screw. This screw fits into the door handle of LG fridges to connect the handle to the stud on the fridge door. I have an LG LFX31945ST and this screw fit the door handle and helped me attach the handle. I lost the original screw when moving and this replaced it. Highly recommend appliance parts pros. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
