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.

XPARTCO W10837240 Dryer Idler Pulley
The XPARTCO W10837240 is an aftermarket replacement idler pulley assembly compatible with select Whirlpool, Maytag, Amana, Kenmore, KitchenAid, Crosley, Admiral, Inglis, and Roper dryers. The idler pulley maintains correct tension on the drive belt, allowing the belt to spin the dryer drum smoothly and consistently. When the idler pulley wears out, the belt loses tension — causing squeaking, grinding noises, or a drum that stops spinning entirely.
This complete assembly includes the idler arm, pulley, and bracket — everything needed for a direct drop-in installation. The pulley is 2-1/8 inches in diameter and the overall assembly measures 6-1/4" L x 1-1/4" W x 3-7/16" H. It directly replaces OEM part numbers W10837240, W10547287, and W10547290, and fits Whirlpool-family dryers with the lint screen located inside the door. Installs in 15–30 minutes with basic hand tools.
Quick Answer
The XPARTCO W10837240 Dryer Idler Pulley fixes dryers that are squeaking, grinding, or have a drum that won't spin due to lost belt tension. Includes idler arm, pulley, and bracket. Pulley diameter 2-1/8". Compatible with select Whirlpool, Maytag, Amana, Kenmore, KitchenAid, Crosley, Admiral, Inglis, and Roper dryers. Fits models with lint screen inside the door.
Common Problems This Part Fixes
Loud squeaking or squealing noise during dryer operation

Installation Notes
⚠️ Safety First — Unplug Dryer Before Starting Unplug the dryer from the power source (and shut off the gas supply for gas dryers) before beginning any repair. Remove the lint screen and unscrew the Phillips screws inside the lint screen housing. Use a putty knife to release the top panel clips and lift the top panel. Remove the front panel to access the drum and drive components. Release the drive belt tension by pushing the idler arm, then slide the belt off the idler pulley. Remove the mounting screw securing the old idler arm assembly and lift it out. Install the new W10837240 idler assembly, secure with the mounting screw, then re-route the drive belt around the new pulley and motor pulley. Reassemble the front panel, top panel, and restore power before running a test cycle. Tip: While the dryer is open, inspect the drum belt (WPW10112954) and drum support rollers for wear and replace if needed. Tools needed: Phillips screwdriver, putty knife or flat pry tool.
Frequently Asked Questions
What does the idler pulley do?
The idler pulley is a spring-tensioned wheel mounted on an arm and bracket inside the dryer. It presses against the drive belt to maintain the correct tension needed to keep the belt gripping the drum and motor pulley. Without proper tension, the belt slips, loses contact, or causes the drum to stop spinning. A worn or seized idler pulley is one of the most common causes of dryer squeaking and drum spin failure.
Does W10837240 replace W10547287 and W10547290?
Yes. The W10837240 is the updated part number that directly supersedes both the W10547287 and W10547290 idler pulley assemblies. If your dryer originally used either of those older part numbers, the W10837240 is the correct current replacement.
How do I know if my lint screen is inside the door?
Open the dryer door and look for a slot or housing just inside the door opening — typically at the top or bottom of the door opening — where you pull out the lint filter. If the filter pulls out from inside the door frame, the W10837240 is designed for your dryer style. If the lint screen pulls out from the top of the dryer cabinet, contact our support team with your model number to identify the correct idler pulley for your machine.
Should I replace the drive belt at the same time?
Yes — since the dryer is already disassembled to replace the idler pulley, it is highly recommended to also inspect and replace the drum belt (WPW10112954) at the same time. The belt and idler pulley wear together, and a worn belt on a new pulley — or vice versa — significantly shortens the life of the new part.
Is this an OEM or aftermarket part?

12638000004021 Genuine OEM Midea Dryer Drum Roller
The 12638000004021 is a genuine Midea OEM dryer drum support roller, sold under the Frigidaire/Midea manufacturing relationship for Midea-built dryers and select Frigidaire, Insignia, and Kenmore dryers using this same platform. This roller sits underneath the drum, along its rear 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. It directly replaces 5304511415, AP7990985.

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 12638000004021 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.
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.
