LG T600 Dryer Motor Not Spinning Properly

LG T600 dryers are known for their reliability, but even the most dependable appliances can develop issues. One problem that many owners encounter is a motor that does not spin properly. When the drum stalls or turns very slowly, it can leave clothes damp and increase drying times. Understanding the root causes, learning how to diagnose the problem, and following a systematic repair approach can save time and money—and keep your laundry routine running smoothly.

Recognizing the Symptoms

Before diving into repairs, it is important to confirm that the issue is indeed related to the motor or its associated components. Look for the following signs:

• The dryer runs but the drum does not rotate, or it turns at a fraction of the normal speed.
• You hear a faint whir or ticking instead of the usual humming motor noise.
• The dryer stops after a few cycles, then starts again with the same issue.
• There is a sudden loss of power to the motor, indicated by a flickering indicator light or a “motor failure” message on the display.
• The dryer’s cycling indicator light may stay on or blink irregularly while the drum remains still.

If the drum moves normally but the clothes do not dry efficiently, the problem is more likely a heat source or sensor fault rather than the motor.

Safety First

1. Unplug the dryer: Always disconnect the appliance from the electrical supply before inspecting or working on it. Even if the dryer is unplugged, internal capacitors can hold a charge.
2. Use insulated tools: Work with tools that have insulated handles to reduce the risk of electrical shock.
3. Wear safety glasses: Protect your eyes from lint, debris, or any small parts that may become airborne.
4. Avoid working on a dryer that has been plugged in for more than an hour: Heat buildup can make the motor and surrounding components hot to the touch.

Common Causes of a Stalling Motor

Faulty Motor

The motor may have suffered from overheating, manufacturing defects, or wear over time. When the windings deteriorate, the motor cannot produce enough torque to rotate the drum.

Broken or Loosened Drive Belt

The belt transfers power from the motor to the drum. If the belt has snapped, frayed, or slipped off the pulleys, the motor may run, but the drum will not turn.

Damaged Drum Rollers

Rollers provide support and reduce friction. When they become worn, they can create excessive resistance, causing the motor to struggle and eventually stop.

Faulty Idler Pulley

The idler pulley maintains belt tension. A worn or broken idler can allow the belt to slip, reducing torque transfer.

Faulty Motor Coupler

Some models use a coupler to connect the motor to the transmission. If the coupler breaks or disconnects, the motor will run, but no power reaches the drum.

Electrical Control Issues

A malfunctioning control board or relay can cut power to the motor at random intervals. Additionally, a bad sensor may misread motor temperature and shut the motor down.

Lint or Debris Obstruction

Excess lint or foreign objects lodged in the drum or along the belt path can create resistance that forces the motor to overheat or stall.

Diagnostic Steps

1. Visual Inspection

• Remove the dryer’s front panel to access the motor compartment.
• Check the drive belt for cracks, fraying, or breakage.
• Inspect the idler pulley for smooth rotation and proper tension.
• Look for visible damage on the motor shaft and any bearing wear.
• Examine the drum rollers for wear or obstruction.

2. Test Motor Resistance

A simple multimeter test can determine if the motor windings are intact.

• Set the multimeter to ohms (Ω).
• Disconnect the motor leads from the control board.
• Measure resistance between each pair of motor terminals.
• Compare readings to the manufacturer’s specifications. A reading of “infinite” or “no continuity” indicates a broken winding.

3. Test Motor with a Power Source

If the motor appears healthy from the resistance test, you can apply a small amount of direct current to see if it spins freely.

• Use a 12‑volt power supply (or the voltage specified for your model).
• Connect the power supply to the motor terminals, observing proper polarity.
• If the motor turns smoothly, the problem lies elsewhere. If it does not spin or only spins slowly, the motor itself is defective.

4. Check the Belt Path

• With the dryer unplugged, manually rotate the drum. It should turn freely without resistance.
• If resistance is felt, the drum rollers or bearings may be worn.
• Tighten or replace the idler pulley if the belt appears slack.

5. Verify Electrical Connections

• Inspect all wiring harnesses for signs of damage, corrosion, or loose connections.
• Ensure the motor control board receives power and that the motor relay is functioning.

Step‑by‑Step Repair Guide

Below is a practical approach to fixing a motor that is not spinning properly. Each section provides a clear, non‑numeric instruction set to follow.

Replacing the Drive Belt

1. Remove the front panel: Use a flathead screwdriver or the tool recommended by LG to pry the panel away.
2. Take note of belt routing: Before removing the belt, draw a diagram or take a photo so that you know the exact sequence of pulleys.
3. Loosen the idler pulley: Release the tension screw on the idler pulley until the belt can slide off the drum and motor pulleys.
4. Slide the belt off: Remove the old belt from the motor and drum pulleys.
5. Install the new belt: Follow the routing diagram, placing the belt over the motor, idler, and drum pulleys in the correct order.
6. Tighten the idler: Tighten the idler pulley screw until the belt has proper tension (there should be a slight give but not slack).
7. Reassemble: Replace the front panel and secure it.

Replacing the Motor

Motor replacement is more involved and requires precise disassembly.

1. Disconnect the motor: Identify and detach the wiring harness from the motor terminals.
2. Unbolt the motor: Remove the mounting bolts that secure the motor to the dryer frame.
3. Lift the motor out: Carefully remove the motor, taking note of its orientation.
4. Prepare the new motor: Verify that the replacement motor matches the model number and specifications.
5. Install the new motor: Place the motor in position, secure it with mounting bolts, and reconnect the wiring harness.
6. Recheck alignment: Ensure the motor shaft is centered on the drum and that there is no binding.
7. Reassemble: Replace the front panel.

Replacing the Idler Pulley

1. Loosen the idler tension screw: Use the appropriate screwdriver or Allen key.
2. Remove the idler pulley: Slide it off the motor shaft.
3. Install the new pulley: Place the new pulley on the shaft and align it with the belt path.
4. Tighten the tension screw: Adjust until the belt has the correct tension.
5. Verify operation: Rotate the drum manually; it should turn freely.

Replacing Drum Rollers

1. Access the rollers: Remove any screws or fasteners holding the drum housing in place.
2. Remove the rollers: Unscrew each roller individually.
3. Check for wear: Measure the roller diameters or compare to a new roller.
4. Install new rollers: Secure each new roller with the original screws.
5. Reassemble: Reattach the drum housing and secure all fasteners.

Replacing the Motor Coupler

1. Locate the coupler: It sits between the motor shaft and the transmission.
2. Disconnect: If the coupler is held by a screw, loosen it; if it is a snap‑fit design, gently pry it off with a flathead screwdriver.
3. Remove the old coupler: Take it out carefully, noting how it was positioned.
4. Install the new coupler: Slide it onto the motor shaft, then secure with the original screw or snap it into place.
5. Test: Run the dryer on a low heat setting to confirm proper operation.

When Professional Help Is Needed

Even with a systematic approach, some problems are better handled by a certified technician. Consider calling a professional if:

• You are uncertain about working with electrical components or high-voltage systems.
• The motor or control board shows signs of damage that cannot be repaired by simple replacement.
• The dryer still fails to operate correctly after you have replaced all visible components.
• You encounter a persistent “motor failure” diagnostic code that does not resolve after troubleshooting.

Professional technicians have access to OEM parts, specialized tools, and detailed service manuals that can streamline repairs and ensure safety.

Maintenance Tips to Avoid Future Motor Issues

1. Clean the lint filter after every load. A clogged filter forces the dryer to work harder, increasing motor load.
2. Run the dryer on a shorter cycle if you notice it heating up excessively; this prevents the motor from overheating.
3. Keep the venting system clear: Check the duct and vent outlet for lint buildup on a monthly basis.
4. Inspect the drum periodically: Look for visible signs of wear on rollers and the belt.
5. Avoid overloading the dryer; too many garments can cause excessive strain on the motor.
6. Use a dryer cleaning kit once every three to six months to remove lint and debris from internal components.

By incorporating these simple habits into your routine, you reduce the likelihood of motor wear and prolong the life of your LG T600 dryer.
