Understanding the Problem
What this covers: Dryers use a drive belt to turn the drum and small support wheels or drum rollers (and a rear glide bearing) to keep the drum aligned and spinning smoothly. Worn rollers/wheels or a frayed/broken belt cause squeaks, thumping, scraping sounds, rubbing, slow spin, or a drum that won't turn. Diagnostic & repair steps: 1) Safety first: Unplug the dryer and shut off gas if it is a gas dryer. Move the dryer away from the wall so you can access the back and sides. Wear gloves and eye protection. 2) Confirm symptoms: Open the door and try to rotate the drum by hand. Note any rough spots, grinding, or resistance. Listen for squeaks or scraping while you manually spin the drum. 3) Inspect the belt: Remove the top and front panel (or access panel) depending on your model so you can see the drum and belt. If the belt is broken, frayed, glazed (shiny), or slipped off the drum/engine, it needs replacement. A broken belt is an immediate cause of a non-turning drum. 4) Inspect rollers/wheels and glide bearing: - Locate the drum rollers (usually 2–4 small wheels on shafts) and spin each by hand. They should turn freely and quietly. If they wobble, are seized, have flat spots, or the rubber is glazed/chewed, replace them. - Check the rear glide bearing or felt bearing pad at the back of the drum. If the drum drags on the pad, or you see worn material, replace the glide bearing or pad. 5) Inspect the idler pulley and motor pulley: The idler pulley maintains belt tension. If the idler is sticking, noisy, or the spring is weak, it allows slipping and should be replaced. Also check motor pulley for damage. 6) Remove the drum: If rollers are inaccessible, remove the drum by taking out the front panel, unhooking the belt from the motor and idler, and lifting the drum out. Keep track of the belt routing or take a photo. 7) Replace failed parts: Install new rollers/wheels (or full roller kit), new glide bearing/pad, and a new drive belt as needed. Replace the idler if noisy or worn. Most technicians replace the rollers and belt together because wear on one often accompanies wear on the other. 8) Reassemble and test: Reinstall the drum, route the belt around the drum, loop it over the motor pulley and idler, and ensure proper tension. Reattach the front/top panels and reconnect power. Run a short, empty cycle to verify smooth, quiet operation and that the drum turns normally. Practical how-to highlights: - Take pictures of belt routing and roller locations before disassembly. - When installing the belt, make sure the ribs of the belt ride on the motor pulley and idler the correct direction (ribs into the pulley grooves). - If replacing rollers, grease is not normally required—use OEM rollers. Do not lubricate plastic rollers with common grease. Safety note: Always disconnect power (and gas for gas dryers) before working on the dryer. If you aren’t comfortable with electrical or mechanical repairs, hire a qualified appliance technician.

Helpful Repair Tip
To quickly confirm a bad roller, spin each roller by hand with the drum in place—if a roller is rough, sticky, wobbly, or doesn't spin freely it needs replacement. A snapped or visibly frayed belt is an immediate replace.
Frequently Asked Questions
How difficult is it to replace the belt and rollers myself?
Difficulty: moderate. Basic hand tools (screwdrivers, nut drivers) are required and the job typically takes 45–90 minutes. If you can remove panels, keep track of screws, and follow photos for belt routing, you can do it. If you’re unsure about electrical disconnects or panel removal, call a technician.
Should I replace the belt and rollers at the same time?
Yes—it's good practice to replace the belt and rollers together. When rollers wear, they add extra drag on the belt. Installing new rollers with an old belt risks early belt failure; replacing both is a small additional cost and reduces repeat service.
