Midea Dryer Tensioner Pulley 12138200006883 – Fix Squealing, Belt Slipping & Drum Stopping Fast
Your Midea dryer is squealing loudly, the belt keeps slipping off, or the drum stops turning mid-cycle — and the tensioner pulley is almost always the cause. In most Midea dryers, the tensioner (idler) pulley maintains constant tension on the drive belt, keeping it seated on the drum and motor pulley throughout the cycle. When the pulley seizes, wobbles, or its bearing fails, the belt loses tension, squeals, slips off, or snaps entirely. ⚡ Common wear item in Midea-built dryers. Part 12138200006883 is the correct replacement tensioner pulley that restores proper belt tension and quiet, reliable drum rotation.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your Midea dryer powers on and the motor runs
- ✔ The drum belt is intact (not broken) but slipping or squealing
- ✔ You can hear a squealing or grinding noise from the pulley area
- ✔ ONLY problem is belt noise, belt slipping off, or drum stopping intermittently

🔧 Common Symptoms
- Loud squealing or screeching noise during the drying cycle
- Drive belt repeatedly slipping off or coming loose
- Drum stops turning mid-cycle then restarts
- Grinding or rattling noise from inside the dryer cabinet
✔ If these symptoms match, this is the most likely worn component in the belt drive system.
✔ In most cases, replacing the tensioner pulley eliminates the noise and restores consistent drum rotation immediately.
📦 Part Details

- Type: Dryer Tensioner Pulley (Idler Pulley)
- Replaces: 12138200006883 — OEM direct replacement
- Brands: Midea
Replace the drive belt and drum support wheels at the same time. A seized tensioner pulley puts extreme stress on the belt and drum wheels — if the pulley has failed, the belt is likely glazed or cracked and the drum wheels are at the same wear stage. Replacing all three in one visit is the most cost-effective repair and prevents a callback within months.
⚙️ Installation
Skill Level: Moderate — 30–40 minutes. Disconnect power before servicing. Remove the dryer front or top panel to access the belt and pulley assembly. Release belt tension by pushing the tensioner pulley toward the motor, slide the belt off, then remove the pulley from its mounting bracket. Install the new 12138200006883, route the belt back around the drum, motor pulley, and new tensioner pulley, then reassemble the panel. Restore power and run a test cycle to confirm quiet operation.

💡 Pro Tip
With the belt off, spin the tensioner pulley by hand. A good pulley spins freely and smoothly with no roughness or wobble. If it grinds, catches, or wobbles side-to-side, the bearing has failed and 12138200006883 is your fix. This 10-second test confirms the diagnosis and rules out the motor or drum wheels as the noise source.
