Quick answer: A dryer that takes three hours on a damp load isn’t usually broken — it’s choked. Cause order, free fixes first: glazed lint filter (fabric-softener residue seals the mesh), blocked or kinked exhaust vent, failed heating element (drum tumbles barely warm), stuck cycling thermostat (cuts heat off too early), stretched drive belt (drum barely turns). Heat-pump dryers add one more — the second lint filter behind the condenser. Clear the airflow before you spend a dollar on parts.

Free fixes first — don’t call a tech yet
Most “takes forever to dry” dryers don’t need a part. They need ten minutes of airflow housekeeping.
1. Pull the lint filter and hold it up to the light. If you can’t see daylight through the mesh, that’s your fault. Fabric softener sheets and synthetic-fibre residue glaze over the mesh — looks clean, even feels clean, but air can’t pass. Wash it under hot water with a stiff brush. Two minutes. Free.
2. Pull the vent hose off the back and shake it out. Disconnect both ends, shake it over a bin — you’ll likely get a brick of compacted lint. Check it isn’t kinked behind the cabinet or stretched twice as long as it needs to be. Every extra metre cuts airflow.
3. Check the external vent louvres outside. Birds nest in them. Spiders web them shut. Lint cakes the flapper closed. Get a torch on it and clear what you find.
Try a load. If drying time is back to normal, you’ve just saved $200+ on a callout. If it’s still slow, work the list below.
Cause hierarchy (top to bottom)
| Likelihood | Fault | The tell |
|---|---|---|
| Most common | Clogged lint filter / vent | Damp loads need 2-3 cycles |
| Common | Heating element partial fail | Drum tumbles, barely warm |
| Common | Cycling thermostat drifted | Drum briefly warm then cold mid-cycle |
| Less common | Drive belt slipping | Slow tumble, clothes bunched not spread |
| Heat-pump only | Condenser filter blocked | Hot cabinet, damp clothes |
Heating element — partial failure is the sneaky one
A dead element = no heat at all (see dryer not heating but spinning). But elements can also fail partially — one coil burns through, the drum gets warm but never properly hot, the cycle runs its full time and clothes are still damp.
Test: ohms across the element terminals, dryer unplugged at the wall. Healthy = roughly 10-50 Ω depending on model. Reading much higher than the model spec = partial fail.
Examples we stock for the brands we see most:
- Stirling / Tempo dryer heating element (GYJ45-68, GYJ40-88)
- Fisher & Paykel condenser dryer heater (DC8060P3, DE8060P1, DE8060P2)
- Baumatic heat-pump dryer heater (BCD70, BCD71)
For Westinghouse, Simpson and Electrolux EDV-series elements, or any of the parts above, run your model through the Part Finder — model in, exact-fit element out. Or browse dryer parts directly.
Cycling thermostat — the heat-cutting-off-early fault
If lint and vent are clear and the element ohms out fine, suspect the cycling thermostat — a disc clipped to the heater duct that’s meant to open at ~60-70°C, then close again as the air cools. When the bimetal disc drifts, it opens too early — drum briefly warm, thermostat kills the element, drum cools, clothes never dry.
The tell: hand on the drum glass through the cycle. Briefly warm, then cold, then briefly warm again = cycling thermostat opening too early. Test in ohms mode — full procedure in our dryer not heating but spinning walk-through.
Belt slipping = less tumble = slow drying
A stretched drive belt means the drum turns more slowly, clothes bunch instead of tumbling evenly, less wet fabric meets hot air. Drying time doubles even though the heat circuit is fine.
Symptoms: drum sounds laboured, clothes come out in a clump, sometimes a slap or squeak from underneath.
Common belts we stock:
- Electrolux dryer belt 1930mm (P/N 0198-300-010-0819) — EDV505/605 series.
- Simpson Maxidry dryer fan belt — Maxidry small range.
- Beko condenser dryer belt (P/N 491500303) — Beko condenser.
For F&P, Haier and Bosch dryer belts, or any of the above, run your model through the Part Finder — or browse dryer parts.
Heat-pump dryers — check the second lint filter
Heat-pump dryers (F&P/Haier DH8060 series, Beko BDPB904HW, Bosch heat-pump range, Esatto EHPD) have a second lint filter behind a service flap at the bottom of the cabinet — the condenser filter. Most owners never know it exists. Clogged condenser filter = no heat exchange = cabinet stays hot but air doesn’t dry the clothes.
Pull it. Rinse it under the tap. Refit. That single fix sorts most “heat-pump takes forever” calls. If it’s clean and still slow, the F&P/Haier exhaust sensor may be reading wrong and ending cycles prematurely — browse dryer parts or run your model through the Part Finder. Sealed-circuit compressor faults are tech territory.
FAQs
My dryer used to dry a load in 45 minutes, now it takes 2-3 hours — what changed?
The lint filter has almost certainly glazed over with fabric-softener residue, or the vent hose has built up lint. It’s gradual — you don’t notice until cycle times double. Wash the filter in hot water with a brush, shake out the hose, clear the external vent. Fixes it most of the time.
I’ve cleaned the filter and vent and it’s still slow — what next?
Test the heating element in ohms mode (warm but never hot = partial element fail), then the cycling thermostat (warm then cold mid-cycle = cutting heat too early), then the drive belt (slow tumble, squeak underneath). Work in that order.
How hot should a healthy dryer get?
A vented dryer on high heat should be uncomfortable to touch the drum glass for more than a couple of seconds within a minute of starting. A heat-pump dryer runs cooler by design — pleasantly warm, not hot — and takes longer per cycle even when working perfectly. Don’t compare heat-pump cycle times to vented ones.
My condenser dryer feels really hot but clothes come out damp — bad sign?
Classic blocked condenser. Heat’s being made but not exchanged out. Pull the condenser filter behind the flap at the bottom front of the cabinet, rinse it under the tap, refit. Fixes most “hot cabinet, damp clothes” cases.
Will running two cycles back-to-back hurt the dryer?
It tells you something — if two cycles only just dry a load that used to dry in one, the dryer’s lost roughly half its drying capacity. Long-term running with restricted airflow also fatigues the thermal fuse and shortens the element’s life. Diagnose it, don’t work around it.
