Frigidaire Dryer Drum Not Turning But Motor Runs — 4 Causes & How to Fix
You toss in a load of wet laundry, hit start, and hear the motor humming away. But when you open the door ten minutes later, everything's still soaking wet and bunched up in the same spot. The drum isn't spinning at all.
This is the classic signature of a broken drum belt — and it's one of the most common dryer failures across Frigidaire, Electrolux, and Kenmore models. The good news? It's a moderate DIY fix that'll save you $150–200 in service calls.
Quick Symptom Check
Before you pull the dryer apart, confirm these symptoms:
- Motor runs — you hear it humming or spinning
- Drum doesn't rotate — stays completely still when you hit start
- No belt debris in the drum or lint trap area (it's fallen inside)
- Drum spins freely by hand when the dryer is off
If all four check out, you're looking at a belt failure 95% of the time.
Cause #1: Broken or Stretched Drum Belt (85% Probability)
The drum belt (part 134503600) wraps around the drum, under the idler pulley, and around the motor shaft. After 8–12 years of use, the rubber deteriorates, cracks, and eventually snaps.
How to diagnose:
- Unplug the dryer completely
- Remove the front panel or top/front access (varies by model — FEQ332ES0 and AEQ6000CES series typically need the front removed)
- Look for the belt around the drum — if it's missing, broken, or lying in the bottom of the cabinet, that's your problem
The fix: Replace with part 134503600 ($15.99). This belt is 92-1/4 inches long and works across dozens of Frigidaire, Electrolux, Kenmore, Gibson, Kelvinator, Crosley, and Tappan models. While you've got the dryer apart, inspect the drum bearing — if it feels gritty or rough, replace it now to avoid another teardown in six months.
Difficulty: Moderate. You'll need to remove panels and thread the belt in a specific pattern (around drum, under idler pulley, around motor). Budget 45–60 minutes.
Cause #2: Seized Idler Pulley (10% Probability)
The idler pulley keeps tension on the belt. If it seizes up due to a failed bearing, the belt can slip off or the motor can't turn the drum even with the belt intact.
How to diagnose: Once you've accessed the belt area, spin the idler pulley by hand. It should rotate smoothly and quietly. If it's stiff, grinding, or won't spin, replace it.
The fix: Replace the idler pulley assembly. Often sold as a kit with the belt. Cost: $12–25 depending on model.
Cause #3: Motor Shaft Issue (3% Probability)
Rare, but if the motor shaft is stripped or the pulley on the motor is loose, the belt won't get driven even though the motor spins.
How to diagnose: With the belt removed, check if the motor pulley is tight on the shaft. Try spinning it — if it slips or wobbles, that's the issue.
The fix: Tighten the motor pulley set screw or replace the motor if the shaft is damaged. Motor replacement runs $80–150 plus labor.
Cause #4: Drum Bearing Failure (2% Probability)
If the rear drum bearing has completely seized, the motor might not have enough torque to turn the drum even with a good belt.
How to diagnose: With the belt off, try spinning the drum by hand. It should rotate easily. If it's extremely stiff or won't budge, the bearing is toast.
The fix: Replace the drum bearing/glide kit. Since you're already in there for the belt, now's the time. Cost: $20–40.
When to Call a Pro
If you're uncomfortable removing dryer panels or if your model requires removing the drum completely (some do), hire a tech. Also call if:
- The motor won't run at all (not just the drum)
- You smell burning rubber but the belt looks intact
- You've replaced the belt and it breaks again within a week
Those point to deeper mechanical or electrical issues.
Frequently Asked Questions
How long does a Frigidaire dryer belt last?
Typically 8–12 years with normal use. High-volume households (families with kids, frequent loads) might see failure closer to 6–8 years. The belt gradually stretches and cracks from heat cycling.
Can I use the dryer if the drum doesn't spin?
No. Running the motor without the drum turning serves no purpose — your clothes won't dry, and you risk overheating the motor or burning out the thermal fuse.
Will part 134503600 fit my Kenmore dryer?
Most likely, yes. This belt replaces AP3865318, 5303283471, 134163400, and 1156784 across Frigidaire-manufactured Kenmore 70-series, 80-series, and some 90-series dryers. Check your model number against the compatibility list or match your old belt's length (92-1/4 inches).
