Understanding the Problem
The drive (drum) belt on Electrolux dryers wraps around the drum and connects to the motor (through an idler) to rotate the drum during a cycle. When the belt breaks, stretches, or slips, the drum won’t turn even though the motor may run, or you’ll hear squealing, thumping, or burning smells. Follow these diagnostic and repair steps to confirm and replace the belt: 1) Confirm the symptom: try to spin the drum by hand with the dryer off. If the drum spins freely with no resistance or stops abruptly, the belt may be broken or severely worn. If the motor hums or runs but the drum doesn’t turn, that’s another strong sign. 2) Unplug the dryer and turn off gas (if gas dryer). Safety first: disconnect power before opening any panels. 3) Access the belt: for most Electrolux models remove the lint screen and unscrew/tilt the front panel or remove the rear access panel, depending on model. Consult your model’s service manual for panel removal steps. 4) Visually inspect the belt: look for breaks, fraying, glazing (shiny surface), or oil/heat damage. Also check belt alignment in the drum groove and pulleys. 5) Check related parts: inspect the idler/tensioner pulley for free spin and no roughness; check drum rollers/gliders for wear; and check motor pulley for damage. A locked or noisy idler or seized roller can wear out or break a belt quickly. 6) Remove the old belt: release idler tension and slip the belt off the motor pulley and drum. Note the routing (take a photo) so you can install the new belt correctly. 7) Install the new belt: route the new belt in the drum groove, loop it around the idler/tensioner and motor pulley as per routing. Pull the idler to apply tension and ensure the belt seats correctly in all grooves. 8) Manually rotate the drum 2–3 turns to confirm smooth movement and correct tracking. If it binds or slips, re-check routing and idler/motor pulleys. 9) Reassemble panels, reconnect power, and run a short cycle to verify normal operation—listen for unusual noises and confirm drum rotation under load. 10) If the new belt fails again quickly, replace or repair the idler pulley, drum rollers, or motor as needed; misalignment or seized components are usually the cause of repeat belt failures. Safety note: always disconnect electrical power before servicing. If you’re not comfortable working around gas connections, or if the dryer requires complicated disassembly, call a qualified technician.

Helpful Repair Tip
To confirm the belt is the problem without full disassembly: unplug the dryer and try to rotate the drum by hand. If the drum won’t turn and you hear the motor running when a cycle starts, the belt is likely broken or slipped off the drum.
Frequently Asked Questions
How much does replacing an Electrolux dryer belt cost?
The belt itself typically costs $15–$40 depending on OEM vs aftermarket and model. If you hire a technician, labor can add $80–$150 depending on local rates and access difficulty. Replacing the belt yourself can save labor costs if you’re comfortable with basic tools.
Can I run the dryer with a broken belt?
No. Running the dryer with a broken or slipping belt can damage the motor from overwork and create a burning smell or smoke. Don’t use the dryer until the belt is replaced and related components (idler, rollers) are checked.
