What the dryer drum belt does — and how to spot a failed one
The drum belt is a long, thin rubber band that wraps around the entire dryer drum and loops down to a small pulley on the motor shaft, kept tight by a spring-loaded idler pulley. When the motor spins, the belt drags the drum around so your clothes tumble. It is the single most common failure point in tumble dryers because it carries the full load weight on a thin strip of rubber that hardens with age and heat.
Classic symptoms of a failed belt: the motor hums or runs but the drum sits still; a loud squeal or thumping as a worn belt slips; or a hot rubber / burning smell from belt material being shredded. If you can spin the drum freely by hand with the door open and it offers no resistance, the belt has snapped. These signs apply across vented, condenser and heat-pump dryers alike.
Vented vs condenser vs heat-pump — does belt replacement differ?
The drum belt principle is identical across all three dryer types — but access, belt length and cost vary. Use the table below to set expectations before you order.
| Dryer type | How it works | Belt access | Typical AU brands | Belt cost (AUD) |
|---|---|---|---|---|
| Vented | Blows hot moist air out a duct/wall | Rear or top panel; easiest | Simpson, Westinghouse, older Electrolux | $25–$45 |
| Condenser | Condenses moisture into a tank | Front/top panel; moderate | Electrolux, Bosch, Fisher & Paykel | $35–$60 |
| Heat-pump | Recycles heat, no venting needed | Tighter layout; more dismantling | Hisense, Bosch, Electrolux, Haier | $45–$70 |
A heat-pump dryer is a dryer that reuses its own warm air through a refrigerant circuit, so it is energy-efficient but packed tightly inside — expect more panels to remove. A condenser dryer collects water in a tank you empty. Belt routing is the same loop in every case: drum → idler → motor pulley. Always match the belt to your exact model number, because belt circumference differs between platforms even within one brand.
Why you should replace the idler pulley at the same time
The idler pulley (also called the tensioner) is a small spring-loaded wheel that keeps the drum belt tight. When a belt fails, the idler is almost always worn too — its bearing dries out and seizes, which is often what shreds the new belt within weeks. Many savvy DIYers and technicians replace both together as a kit.
That is why several Oz Appliance Spares listings bundle the idler pulley 0197300040 with the drum belt 0198300011 for Simpson, Eziloader, Eziset and Westinghouse dryers — fitting both in one go saves a second teardown. Signs of a bad idler: a rumbling or grinding noise during the cycle, a glazed or grooved pulley wheel, or a wheel that won’t spin smoothly when flicked by hand. Replacing a $15 pulley while you’re inside is cheap insurance against repeating the whole job. If the new belt squeals immediately after fitting, a worn idler is the usual culprit.
Step-by-step: replacing a dryer drum belt
Safety first: This is 240V mains work. Unplug the dryer at the wall before removing any panel. If you are unsure, use a licensed technician (AS/NZS electrical safety standards apply).
- Unplug and position — pull the dryer out and unplug it. For wall-mounted dryers, take it off the bracket and lay it on a soft surface.
- Open the cabinet — remove the screws holding the rear or top/front panel (varies by type — see table above). Photograph the old belt routing before anything moves.
- Release tension — push the idler pulley arm to slacken the old belt, then slip the belt off the motor pulley and remove it.
- Inspect the idler — spin the pulley; if it grinds or sticks, replace it now.
- Fit the new belt — loop it around the drum (grooved side against the drum on poly-V belts like the 7PH1975/7PH1992), then around the idler and motor pulley following your photo.
- Reassemble and test — refit panels, plug in, and run a short cycle listening for smooth, quiet rotation.
Is it the belt — or the motor / capacitor?
Before you order, confirm the belt is actually the fault. A snapped belt and a dead motor produce different symptoms. Use this quick diagnostic table.
| Symptom | Likely cause | Action |
|---|---|---|
| Motor hums, drum free-spins by hand, no resistance | Snapped or stretched belt | Replace belt (+ idler) |
| Loud squeal, drum still turns slowly | Worn belt slipping / glazed idler | Replace belt + idler pulley |
| Motor totally silent, no hum at all | Failed motor or start capacitor | Test capacitor; replace motor if dead |
| Drum turns but stops mid-cycle, clicks | Thermal overload / motor overheating | Check airflow, motor windings |
| Burning smell, drum won’t move | Belt shredded around seized idler | Replace both immediately |
The key test: with the dryer unplugged, open the door and spin the drum by hand. Free and weightless means the belt is off. Firm resistance means the belt is intact and you should investigate the motor, capacitor or a jammed drum bearing instead. A start capacitor that has lost capacitance will let the motor hum without starting — a different fix entirely.

Frequently Asked Questions
How do I know if my dryer belt is broken or just slipping?
Unplug the dryer and spin the drum by hand. If it turns freely with no resistance, the belt has snapped. If it offers firm resistance but squeals or slips during a cycle, the belt is stretched or the idler pulley is glazed — replace both.
Should I replace the idler pulley with the belt?
Yes, in most cases. A worn idler bearing is often what destroyed the original belt, and a seized pulley will shred a new belt quickly. Kits like the Simpson/Westinghouse 0197300040 idler with belt 0198300011 are designed to be fitted together.
How much does a dryer drum belt cost in Australia?
Genuine belts run roughly $25–$70 AUD depending on type — vented dryers at the low end, heat-pump dryers at the higher end. Combined belt-and-idler kits sit around $35–$55. That is far cheaper than the $150+ a technician callout typically costs.
Is replacing a dryer belt safe to DIY?
The mechanical part is straightforward, but it is 240V mains equipment. Always unplug at the wall first. There is no live electrical work in a belt swap, but if you are uncomfortable opening the cabinet, use a licensed technician under AS/NZS standards.
Why does my new dryer belt keep breaking or squealing?
The most common cause is a worn or seized idler pulley that wasn’t replaced, putting uneven tension on the belt. Incorrect routing or fitting a belt of the wrong circumference for your model will also cause early failure.
Can I use any belt or does it have to match my model?
It must match your model. Belt length and profile (for example poly-V 7PH1975 vs 7PH1992) vary between platforms even within one brand. Always check your model number against the fitment list or use the Part Finder.
My dryer hums but won’t turn — is it always the belt?
Usually, but not always. A humming motor that won’t start the drum can also be a failed start capacitor. Do the hand-spin test first: a free-spinning drum confirms a broken belt; a firm drum points to the motor or capacitor.
Frequently asked questions
How do I know if my dryer belt is broken or just slipping?
Unplug the dryer and spin the drum by hand. A drum that turns freely with no resistance means the belt has snapped. Firm resistance with a squeal or slipping during the cycle points to a stretched belt or a glazed idler pulley — replace both together.
How much does a dryer drum belt cost in Australia?
Genuine dryer drum belts run roughly $25–$70 AUD — vented dryers at the low end and heat-pump dryers at the higher end. Combined belt-and-idler kits sit around $35–$55, far cheaper than the $150-plus a technician callout typically costs.
How long does it take to replace a dryer drum belt?
Replacing a clothes dryer drum belt is a 45–90 minute DIY job. Vented dryers with rear or top panel access are the quickest, while heat-pump dryers are packed more tightly inside, so expect to remove more panels to reach the belt.
Should I replace the idler pulley when I replace the dryer belt?
Yes, in most cases. A worn idler pulley bearing is often what destroyed the original belt, and a seized pulley will shred a new belt within weeks. Kits pairing the 0197300040 idler pulley with the 0198300011 drum belt for Simpson and Westinghouse dryers are designed to be fitted together.
My dryer hums but the drum won’t turn — is it always the belt?
Usually, but not always. A humming motor that never starts the drum can also be a failed start capacitor. Do the hand-spin test first: a free-spinning drum confirms a broken belt, while firm resistance points to the motor, capacitor or a jammed drum bearing.
Is dryer belt replacement the same on vented, condenser and heat-pump dryers?
The belt routing is the same loop on all three dryer types — drum, idler, then motor pulley — but access differs. Vented dryers open at the rear or top, condenser dryers at the front or top, and heat-pump dryers need more dismantling. Always match the belt to your exact model number.
