2 Pack - 12638000000786 Genuine OEM Midea Dryer Drum Roller
The 12638000000786 is a genuine Midea OEM dryer drum support roller. This roller sits underneath the drum, along its support track, and does the physical work of holding the drum's weight while letting it turn freely as the belt drives it around. A dryer typically uses more than one of these rollers working together to keep the drum properly supported and centered.
Over time, the wheel and bearing inside the roller wear down from the constant heat and rotation the dryer subjects them to, eventually developing a flat spot, seizing up, or simply wearing thin enough that the drum sits unevenly. A worn roller produces a distinctive symptom: a rumbling, squeaking, or thumping noise that rises and falls with drum rotation, often getting louder as a load tumbles or as the roller continues to wear.

Installation Notes
⚠️ Unplug Dryer Before Starting Disconnect power at the outlet or shut off the circuit breaker before beginning. On a gas model, also close the gas shutoff valve before moving the cabinet. Wear work gloves — sheet metal edges inside the cabinet are sharp. Access is typically through the rear panel: remove the screws securing the panel, then release the drum belt from the idler pulley to relieve tension so the drum can be supported and moved slightly for access to the rollers underneath. Photograph the roller and axle positions before removing anything. Remove the retaining clip or fastener holding the worn roller's axle in place, then slide the old roller off. Install the new 12638000000786 roller onto the axle in the same orientation, and secure it with the retaining clip or fastener. While you're in there, check the other rollers by spinning each one by hand — if any feel stiff, gritty, or worn, replace them at the same time, since they're typically the same age and wear on a similar schedule. Re-tension the belt around the idler pulley, reassemble the rear panel, restore power, and run a short empty cycle to confirm the noise has resolved. Tools needed: Phillips screwdriver, nut driver, pliers, work gloves.
Frequently Asked Questions
My dryer makes a rumbling noise that gets louder over time. Is this the part I need?
Yes, this is the classic symptom of a worn drum roller. As the wheel and bearing wear down, the noise typically starts subtle and gradually worsens, often becoming most noticeable with a full load as the extra weight puts more load on the worn wheel. If the noise rises and falls in rhythm with the drum turning, a roller is the most likely cause.
Is this the same roller as your 12638000004021 listing?
No. These are two distinct Midea part numbers, and they do not cross-reference or replace each other. If you're not sure which roller your dryer uses, check the number stamped on your existing roller or contact our support team with your model number, and we'll confirm which one is correct before you order.
Should I replace just one roller, or all of them?
It's worth checking all of them while you have access. Dryers typically use more than one roller supporting the drum, and since they're the same age and under the same stress, if one has worn out the others are often not far behind. Spin each roller by hand — if any feel stiff, gritty, or rough, replace them together to avoid repeating this repair again soon.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by Midea to factory specifications — guaranteed fit, materials, and performance. It matches the original wheel design, bearing, and axle fitment of the drum roller originally installed in your dryer.
