Quick answer: A dryer that still tumbles but blows cold is almost never scrap. The heat has been cut by a tripped safety cut-out (usually a blocked lint path — free to fix), a failed thermostat or overload, or a burnt-out element. A repairer is $100–165 just to show up and $180–380 all up; a new dryer is $700–1,500. The parts here are $18–70. Clear the lint first, then swap the cut-out, element or capacitor in an afternoon and keep most of the cash.

Cold air isn’t a dead dryer
Here’s the mistake that costs people a grand: the drum turns, the timer ticks, but the clothes come out cold and damp — so they decide the dryer’s had it and go shopping. In reality a dryer that still tumbles has a healthy motor and belt. Only the heating side has stopped — and that’s a handful of cheap, separate parts. One has failed, or a safety device has switched the heat off on purpose.
The good news for your wallet: the usual suspects are a $18–30 cut-out or thermostat, a $40–70 element, or a $18–30 run capacitor — and the first thing to check costs nothing at all. Compare that to a repairer’s bill. Most set a one-hour minimum, so even a ten-minute part swap gets billed as a full hour on top of the $100–165 they charge just to attend and diagnose. Here’s how the faults, the parts and the two ways to pay stack up.
| What it’s doing | Usual culprit | DIY part band | Call a repairer | Verdict |
|---|---|---|---|---|
 Tumbles, but the air is stone cold | Tripped safety cut-out / thermal overload (after a blocked lint path) | Clear the lint = $0; a new cut-out and overload is $18–30 | $180–380 (plus the $100–165 call-out) | Fix it — clear lint first |
 Warms weakly, or takes three cycles to dry | Burnt-out heating element | Heating element $40–70 | $180–380 | Usually fix it (some are bigger jobs) |
 Hums or turns slowly, struggles to get going | Tired run capacitor | Run capacitor $18–30 | $180–380 | Fix it — quick swap |
 Damp clothes, endless cycles, lint everywhere | Blocked lint path / torn filter | Clean = $0; a new lint filter is $13–30 | — | Free first |
So even at the worst end — an element plus your afternoon — you spend a fraction of a $180–380 repair bill and a rounding error against a $700–1,500 new machine. You keep roughly 60–80% of the cost. Let’s go through it in order, cheapest and safest first.
Start with the free fix: clear the whole lint path
Before you buy a single part, do this — it’s free and it’s the most common root cause. A dryer needs air moving through it to carry heat and moisture away. When lint clogs the filter, the ducting or the vent hose, hot air gets trapped and the temperature climbs. To stop that becoming a fire risk, a safety cut-out (a thermal overload) switches the heat off. The drum keeps spinning, but the air goes cold — the exact symptom that sends people shopping.
So clear the lot: pull the lint filter and wash it, check behind it, and make sure any vent hose runs clear to the outside and isn’t kinked or packed with fluff. On a vented dryer, run it a minute and feel for strong warm airflow at the outlet. Nine times out of ten this restores the heat on its own. If your filter is torn, warped or missing, that’s a genuine part too — a dryer lint filter is only $13–30, versus a repairer charging a call-out to tell you the same. For step-by-step by brand, the Omega / Euromaid not-heating guide walks the airflow-then-part sequence.
Still cold? The safety cut-out and thermostat
If the airflow is strong and the clothes are still cold, the safety cut-out itself may have blown, or the cycling thermostat has failed. These are small, cheap sensing parts — typically $18–30 — that sit in the heating circuit. A tell-tale sign is a one-shot overload that tripped for good after an earlier blockage and never reset. Some kits pair the parts up, like the Fisher & Paykel capacitor and thermostat-overload set in the table above — two common failure points in one go.
Safety first, honestly: a dryer thermostat and element sit in the mains circuit, so this is not a live-poking job. Isolate the power — switch off at the wall and unplug — before you open anything, and in some cases (a hard-wired or built-in dryer) it may legally need a licensed person. If yours plugs into a standard socket and you’re handy with a screwdriver and a photo of where each wire went, a plug-in vented dryer is an afternoon job. Not sure which part tripped? Match your model number off the sticker, or read the which-element-fits guide first.
Weak heat or no heat: the element
The element actually makes the heat, and it’s the number-one “won’t heat” culprit after the lint path. When it burns through you get no heat at all, or weak heat that drags a load out over two or three cycles. On many vented dryers it sits behind a back or bottom panel and comes out with a few screws and spade connectors — a $40–70 part and a satisfying swap. The Solt / InAlto vented dryer element is a typical straightforward, plug-in example.
Be honest about the machine, though. On a heat-pump dryer the “element” is a sealed heater assembly — a bigger, pricier job, and the one case where the sums get closer. If you’ve got a condenser or heat-pump model, check the Fisher & Paykel condenser not-heating guide or the Omega heat-pump heater guide before you commit. The same safety line applies: an element is mains-voltage — isolate the power, and if it’s hard-wired or you’re not confident, get a licensed person in. Even then, having them fit your part beats a full diagnostic call-out plus markup on the same element.
Humming or turning slowly? Check the run capacitor
This one gets misread as a dead motor. If the drum hums, turns slowly or won’t quite get going — especially if it improves when you nudge it by hand — the culprit is often a tired run capacitor. It gives the motor the kick it needs to start and run; as it weakens the motor labours, runs hot, and loops you right back into cut-outs and cold air. A replacement is a cheap $18–30 part, like this Haier dryer run capacitor.
One safety note that matters here: capacitors store an electrical charge even after the dryer is unplugged. Isolate the power, and if you’re not confident discharging one safely, leave it to a licensed person — it’s still a cheap part for them to fit. Match the microfarad (µF) rating on the old capacitor to the new one; send us the number off it or off your model sticker if you’re unsure.
Fix it or bin it? Run the numbers
A repairer’s call-out and diagnostic fee is $100–165 before a single part or minute of labour, and most bill a one-hour minimum on top. A full not-heating repair lands at $180–380. A new dryer is $700–1,500 once you’ve paid for delivery and disposal. Against that, the parts on this page are $18–70 and the fix is an afternoon at the bench.
- Fix it when the drum still turns and the fault is a lint path, cut-out, thermostat, element or capacitor — the vast majority of “won’t heat” complaints. You keep roughly 60–80% of the cost.
- Weigh it up if it’s a heat-pump heater assembly on an older or budget machine, or if the motor and bearings are also failing. When the parts approach half the price of a new dryer and the machine is well used, replacing can be smarter.
Not sure which part you need? Browse the dryer parts store, or if you want the running-cost side of the decision, the winter dryer running-cost guide compares vented, condenser and heat-pump. Either way, match your model number on the sticker first — use the part finder and you’ll land on the exact part for your machine.
Frequently asked questions
Q: My dryer spins but blows cold air — does that mean it’s dead?
A: No. A turning drum means the motor and belt are fine, so it’s the heating side that’s stopped. That’s usually a tripped safety cut-out from a blocked lint path (free to fix), a failed thermostat or a burnt-out element — parts in the $18–70 range, not a new machine.
Q: Why does my dryer heat for a while, then go cold?
A: That’s the classic overheating pattern from restricted airflow. Lint in the filter, ducting or vent hose traps heat, the safety cut-out switches the element off to protect the machine, then it cools and tries again. Clear the whole lint path first; if it keeps happening, the cut-out or thermostat has likely worn out.
Q: Is replacing a dryer element something I can do myself?
A: On many vented dryers, yes — it’s a few screws and spade connectors behind a panel. But an element is a mains-voltage part: switch off and unplug at the wall first, and if the dryer is hard-wired or you’re not confident, it may legally need a licensed person. Heat-pump heater assemblies are a bigger job.
Q: How do I know if it’s the element or the thermostat?
A: No heat at all often points to a blown overload or a broken element; weak heat that drags a load out points to a failing element. The safest route is to clear the lint path, then match the parts to your model. Send us the number off your model sticker and we’ll help you check which one fits.
Q: Is it really cheaper to fix it than call someone?
A: Almost always. A repairer charges $100–165 just to attend and diagnose, then $180–380 all up with a one-hour minimum. The DIY parts here are $18–70. Even having a licensed person fit a part you supply beats paying a full diagnostic call-out plus their markup on the same part.
