Are you facing a malfunctioning LG washing machine knob that’s hindering your laundry routine? Fret not! This comprehensive guide will provide you with step-by-step instructions and troubleshooting tips to effectively resolve the issue.

Identifying the Problem

Before jumping into repairs, it’s crucial to identify the nature of the knob malfunction. Here are common symptoms to watch out for:

• Loose knob: The knob spins freely or doesn’t engage when turned.
• Stuck knob: The knob won’t budge or turn in either direction.
• Broken knob: The knob has visible cracks or breaks, preventing its operation.

Troubleshooting Steps

1. Check for Obstructions:

Examine the knob for any lint, detergent, or debris that may be obstructing its movement. Clean the knob and its surroundings with a damp cloth.

2. Tighten Loose Knob:

If the knob is loose, use a pair of pliers or a wrench to gently tighten the screw that secures it to the shaft. Avoid overtightening, as this can damage the knob.

3. Free Stuck Knob:

Apply a small amount of lubricant, such as WD-40, around the base of the knob. Allow it to penetrate for a few minutes, then gently wiggle and turn the knob to loosen it up.

4. Replace Broken Knob:

If the knob is broken, you’ll need to replace it. Order a replacement knob compatible with your LG washing machine model.
