A dryer that runs and stays cold is one of the few faults where the cheapest test in the house, clearing the vent run, is also the fix most often needed. The job here starts with a path rather than a part: you are tempted to bypass or hard-wire around a thermal fuse - never do this [S1]. That is why the drum turns but the load comes out cold belongs in the high-risk column before it belongs to any repair, and why unplugged before anything is opened sits at the front of it. clogged vent run (lint restriction) is the first suspect — no part needed [S1], about 45 minutes — and the cheapest item on the list is clogged vent run (lint restriction) [S1]. Owners describe it as dryer runs but stays cold, clothes come out damp and cold, drum turns but there is no heat or takes three cycles to dry a load.
drum turns but there is no heat takes three cycles to dry a load
S1 puts the element at $40-100 in parts and $150-300 installed; S2 at $60-150 in parts and $220-360 installed. A visibly broken or sagging coil is the giveaway; otherwise the coil is tested for continuity. Time basis: no published duration, book estimate.
dryer runs but stays cold clothes come out damp and cold
A technician meters each thermostat and replaces the open one, usually in the same visit as the fuse, because the same overheating event takes both. Time basis: no published duration, book estimate.
drum turns but there is no heat dryer runs but stays cold
The drum turns but the burner never lights. S2 puts the valve coils at $30-60 in parts and an igniter job at $190-300; S1 puts gas igniter or valve repair at $150-350. Time basis: no published duration, book estimate for reaching the burner assembly.
Past ten years, a repair above roughly $400 is hard to justify. Under six years old, nearly every repair on the list is worth doing - and a heat repair on a twelve-year-old machine is close to a coin flip. [S2]
S1 puts dryer life at 10-13 years and S2 sets its replacement threshold at ten years; the decision below uses the ten-year line

dryer runs but stays cold takes three cycles to dry a load
This is the root cause behind most no-heat calls, not just a maintenance chore: when the exhaust cannot escape, the cabinet overheats and the safety fuse cuts the heat. The source calls lint restriction the leading cause of dryer fires, so it has to be cleared end to end before any part is replaced. Time basis: no published duration, book estimate for the full vent run.
dryer runs but stays cold drum turns but there is no heat
A one-time fuse: it blows because of the vent restriction, so replacing it without clearing the vent blows the new one again. S2 prices the parts at $15-45 and the thermostat-and-fuse job at $130-240. Time basis: no published duration, book estimate.
drum turns but there is no heat dryer runs but stays cold
On an electric dryer the drum spins on 120 volts while the heat needs the full 240, so a partially tripped double-pole breaker looks like a dead element. Reset both poles firmly. Free, and worth checking before buying any part.
| Cause | Cost | Time | DIY? |
|---|---|---|---|
| clogged vent run (lint restriction) | no part needed | 45 min | easy |
| only one leg of the 240-volt circuit live | no part needed | 15 min | easy |
| failed cycling or high-limit thermostat | $15–$45 part | 60 min | advanced |
| blown thermal fuse | $10–$30 part | 45 min | easy |
| weak igniter or failed gas valve coils (gas dryers) | $30–$60 part | 90 min | advanced |
| burned-out heating element (electric dryers) | $60–$150 part | 75 min | advanced |
A technician visit starts with a diagnostic fee of $80–$130 [S2]. Completed repairs run $130–$400 [S2].
