How to Replace a Dryer Drum Support Roller
To replace a dryer drum support roller, unplug the dryer, open the cabinet, remove the drum, swap the worn roller on its shaft, and reassemble the dryer. This repair is a good fit when the dryer makes a rumbling, thumping, or grinding noise as the drum turns.
A bad dryer drum support roller usually shows up as noise during tumbling, not just at startup. The roller can wear flat, seize, or wobble on its shaft, which lets the drum ride rough and noisy. If the drum support area looks damaged beyond the roller itself, stop and reassess before putting the dryer back together.
Before you start: Match the roller diameter, shaft style, and dryer compatibility before ordering.
Safety first
- Unplug the dryer before opening the cabinet or handling internal parts.
- Wear gloves when reaching inside the cabinet because sheet metal edges are often sharp.
- Support the drum and front panel as you remove them so they do not drop or twist wiring loose.
- Do not force retaining clips or brackets. If parts do not fit cleanly, recheck the part match and hardware order.

Step-by-step fix
Step 1: Confirm the drum support roller is the likely problem
- Unplug the dryer before touching any panels or internal parts.
- Turn the drum by hand if you can reach it from the door opening. Listen for a rough, scraping, or thumping spot during rotation.
- Think about the noise pattern. A worn drum support roller usually causes rumbling, rhythmic thumping, or grinding while the drum is spinning.
- If the dryer recently started leaving black marks, dragging badly, or the drum feels loose, the support area needs a closer look once opened.
If it works: The symptoms point to a drum support problem and replacing the dryer drum support roller is a reasonable next step.
If it doesn’t: If the noise sounds more like a high-pitched squeal, a blower rattle, or a motor hum without drum movement, inspect those parts before ordering a roller.
Stop if:
- You smell burning insulation, see melted wiring, or find signs of overheating around the drum or motor area.
- The drum is badly misaligned, cracked, or rubbing the cabinet hard enough to suggest a larger support failure.
Step 2: Open the dryer and remove the drum
- Pull the dryer away from the wall enough to work comfortably.
- Remove the lint screen if it sits in the top panel, then take out any screws that secure the top or front panel.
- Open the cabinet carefully and support the front panel as you disconnect it or set it aside, depending on your dryer layout.
- Release belt tension from the idler pulley and slip the belt off the motor pulley.
- Use the belt as a handle and lift the drum out of the cabinet.
If it works: The drum is out and you can clearly see the support roller area.
If it doesn’t: If the cabinet does not open the way you expect, pause and look for hidden screws near the lint screen housing, rear edge, or lower front access area.
Stop if:
- You find damaged wiring, a broken belt path bracket, or a cracked drum support mount.
- The drum cannot be removed because a support shaft or bracket has come apart and is no longer secure.
Step 3: Inspect the roller, shaft, and support area
- Spin the old roller by hand on its shaft. It should turn smoothly without grinding, wobbling, or binding.
- Look for a flat spot, cracked wheel surface, melted bushing area, or heavy lint packed around the shaft.
- Check the shaft and bracket for grooves, heat discoloration, or looseness that could ruin a new roller quickly.
- Vacuum lint and debris from the support area so you can see the parts clearly.
If it works: You have confirmed the roller is worn or seized, and the mounting area is clean enough for replacement.
If it doesn’t: If the roller seems fine but the shaft is deeply worn or the bracket is loose, the repair may need more than just the roller.
Stop if:
- The support bracket is bent, cracked, or pulling away from the cabinet.
- The shaft is badly worn, damaged, or fused to the old roller in a way that prevents a normal replacement.
Step 4: Replace the dryer drum support roller
- Remove the retaining clip, washer, or fastener that holds the old roller on the shaft. Keep the hardware in order as it comes off.
- Slide the old roller off the shaft and wipe the shaft clean.
- Install the new dryer drum support roller in the same orientation as the old one, along with any washers or spacers that came off.
- Reinstall the retaining clip or fastener so the roller is secure but still spins freely.
- If your dryer uses more than one support roller in the same area, compare both sides and replace the worn mate if needed so the drum rides evenly.
If it works: The new roller is installed securely and spins smoothly on the shaft.
If it doesn’t: If the new roller does not sit squarely or bind on the shaft, remove it and recheck the washer order and part fit before forcing anything.
Stop if:
- The new roller does not match the shaft style or mounting hardware.
- The shaft or bracket will not hold the roller securely after reassembly.
Step 5: Reinstall the drum and reassemble the dryer
- Set the drum back into the cabinet and make sure it rests properly on the support rollers.
- Route the belt back around the drum, motor pulley, and idler pulley the same way it was before removal.
- Turn the drum by hand several full rotations to make sure the belt tracks correctly and the drum rolls smoothly.
- Reinstall the front or top panels and tighten the screws evenly.
- Return the lint screen and move the dryer back into place without crushing the vent.
If it works: The dryer is fully reassembled and the drum turns by hand without the old rough spot or heavy rumble.
If it doesn’t: If the drum binds or slips off the support area, reopen the cabinet and check drum seating, belt routing, and roller alignment.
Stop if:
- The drum will not rotate freely by hand after reassembly.
- A panel, bracket, or drum edge is rubbing hard enough to damage the cabinet or drum.
Step 6: Test the dryer under real use
- Plug the dryer back in.
- Run the dryer empty for a few minutes and listen as it starts, tumbles, and warms up.
- If it sounds normal, dry a small load of towels and listen again through a full tumbling cycle.
- Check that the drum turns smoothly, the noise is gone or greatly reduced, and the dryer finishes the cycle normally.
If it works: The dryer runs smoothly in real use and the roller replacement held.
If it doesn’t: If the dryer still makes noise, inspect the other support roller, idler pulley, belt, glides, blower wheel, and motor area for a second worn part.
Stop if:
- The dryer still grinds loudly, smells hot, or shows signs of the drum dragging after the new roller is installed.
- The drum stops turning, the belt jumps off, or the cabinet begins shaking more than before.

FAQ
What does a bad dryer drum support roller sound like?
It usually sounds like a rumble, rhythmic thump, or grinding noise while the drum is turning. A flat-spotted or seized roller often gets louder as the dryer runs.
Should I replace just one roller or both?
If your dryer uses a pair of support rollers in the same area, replacing both is often the better move when one is clearly worn. The second roller may be close behind, and matched wear helps the drum ride evenly.
Can I lubricate a noisy dryer drum support roller instead of replacing it?
If the roller is worn, wobbling, or seized, lubrication is usually only a short-term bandage. A damaged roller or worn shaft area should be replaced rather than masked.
Why is my dryer still noisy after replacing the roller?
Dryers often have more than one wear part in the drum support system. If the noise remains, check the other roller, idler pulley, belt, drum glides or slides, blower wheel, and motor area.
Do I need to clean lint out while I have the dryer open?
Yes. This is a good time to vacuum lint from the cabinet, roller area, and nearby airflow path. Built-up lint can trap heat and make future repairs harder.
