Dryer Not Heating: Causes and Repair Costs (2026)
Quick answer: If your dryer tumbles but produces no heat, the cause is almost always a single failed component — most often a blown thermal fuse, and after that the heating element on an electric dryer or the igniter on a gas dryer. It is a fixable repair, not a dead machine. Across 369 completed no-heat dryer repairs in our own records the ticket ran $320 to $438, median $375, and the part itself is $5 to $60 of that — the visit and the labor are what you are paying for. Check one thing first: the exhaust vent. A clogged vent is what blows the thermal fuse, and a new fuse will blow again if the vent is not cleared.
A dryer that tumbles but produces no heat is one of the most common appliance complaints in U.S. households. The load comes out damp, you run it again, still damp — and by the third cycle you’re wondering whether the machine is broken or just broken-expensive. This guide explains the actual causes, in order of frequency, with repair costs taken from our own completed jobs across Atlanta, Tampa, Jacksonville, Miami, and Charlotte.
A dryer that runs but doesn’t heat is almost always a fixable, single-component failure — not a sign the machine is dying. The failure is usually mechanical or electrical, isolated to one part, while the motor circuit keeps the drum turning.

The Most Common Causes of a Dryer Not Heating
1. Blown Thermal Fuse
The thermal fuse is a one-time-use safety device located on the exhaust duct inside the dryer cabinet. Its job is to interrupt the heating circuit if the dryer overheats — which it does permanently. Once it blows, it doesn’t reset. The dryer continues to tumble normally, which is why this failure is so often misdiagnosed as a mystery.
Why it blows: Almost always a clogged or restricted exhaust vent. When airflow is blocked, heat builds up inside the drum. The fuse blows to prevent a fire. If the vent isn’t cleared before the new fuse is installed, the replacement will blow again — often within weeks.
How it’s diagnosed: A technician tests continuity with a multimeter — a good fuse shows continuity, a blown fuse reads open. The fuse is non-resettable, so it’s replaced regardless, and the vent is cleared at the same visit so it doesn’t happen again.
- Part alone: $5–$15
- Installed by a technician: $255–$435
- Cheap part, but the visit and the labor set the invoice
2. Heating Element Failure (Electric Dryers)
Electric dryers heat air by passing it over a coiled nichrome wire element — essentially a large resistor. Over time (typically 8–12 years of regular use), the coil develops a break, and the circuit opens. The dryer tumbles but produces no heat at all.
Technical note: A partial break in the coil can produce reduced heat rather than no heat — the dryer runs but takes much longer than normal. If your clothes are damp after a full cycle but the dryer does feel warm, that’s a different problem — see our guide on a dryer not drying fast for that diagnostic path.
How it’s diagnosed: Visual inspection for a visible break in the coil, plus a continuity test — a functioning element shows continuity, a broken element reads open.
The one repair on this page that is genuinely DIY-able. If your machine has rear panel access and you own a multimeter, this is a job most people can finish in 45 to 90 minutes with a $20 to $60 part. The full procedure, including how to meter the element before buying anything and why the vent has to be cleared at the same time, is in how to replace a dryer heating element. If the drum has to come out to reach it, that is the point where most DIY attempts stall.
- Part alone: $20–$60 depending on brand
- Installed by a technician: $305–$404 (109 completed jobs, median $346)
3. Gas Igniter Failure (Gas Dryers Only)
Gas dryers use a glow bar igniter to ignite the burner. The igniter heats to approximately 1,800°F to open the gas valve and initiate combustion. These igniters are fragile ceramic components that fail with age — they glow but don’t get hot enough to trip the valve, or they fail to glow at all.
How it’s diagnosed: A technician opens the burner compartment and runs a cycle. If the igniter glows orange-red but the burner never lights, the igniter is likely too weak to open the valve, or the radiant sensor has failed — a common but often overlooked failure mode. If it doesn’t glow at all, the igniter or its circuit is open. Gas components should always be handled by a professional.
- Part alone: $15–$40
- Installed: too few gas-igniter dryer jobs on record to publish a separate band honestly — it falls inside the general no-heat range of $320–$438
4. Cycling Thermostat
The cycling thermostat regulates temperature during normal operation. It opens and closes the heating circuit to maintain the selected temperature. When it fails open (stuck open), the heating element or burner never activates.
Important distinction: A failed cycling thermostat and a blown thermal fuse produce identical symptoms. Technicians test both simultaneously. The cycling thermostat, unlike the thermal fuse, is resettable in design — but when it fails mechanically it must be replaced, not reset.
- Part alone: $10–$30
- Installed by a technician: $300–$382 (31 completed jobs, median $350)
5. High-Limit Thermostat
The high-limit thermostat is a secondary safety device that trips at a higher temperature threshold than the cycling thermostat. It’s designed to cut the heating circuit before the thermal fuse would need to blow. On many machines, it’s mounted directly on the heating element housing.
Unlike the thermal fuse, some high-limit thermostats are resettable — but most modern dryers use non-resettable versions. Failure is less common than the components above but more common than control board failure.
- Part alone: $10–$25
- Installed by a technician: $300–$382 — same bucket as the cycling thermostat
6. Clogged Vent / Airflow Restriction
This is listed separately because it’s not a component failure — it’s a maintenance failure. A fully clogged vent can cause the dryer to overheat (the thermal fuse blows, stopping heat) or to produce heat that escapes inefficiently (clothes take two or three cycles to dry).
What to check:
- The lint trap (every load — always)
- The vent duct from the dryer to the exterior wall
- The exterior vent cap (birds nest in these, screens clog them)
- Duct material: flexible plastic duct is a fire hazard and should be replaced with rigid or semi-rigid metal
7. Control Board
Modern dryers with electronic controls have a main control board that governs heating cycles. Board failures that affect only heat output (with all other functions normal) are uncommon. In practice, a heating problem attributed to the control board without first ruling out every component above has probably been misdiagnosed.
That said, board failures do occur — typically on machines 7+ years old with electronic displays. If every heating component tests good and the wiring harness is intact, the board becomes the remaining suspect.
- Part alone: $100–$300 (varies dramatically by brand and model)
- Installed by a technician: $369–$612 (26 completed jobs, median $479) — the one repair on this list in a different price class
Repair Cost Summary by Cause
Part prices are retail. The right-hand column is not an estimate — it is the middle half of our own completed dryer jobs, covering the part, the labor and the visit.
| Cause | Part alone | Installed by a technician |
|---|---|---|
| Thermal fuse | $5–$15 | $255–$435 |
| Heating element | $20–$60 | $305–$404 |
| Cycling or high-limit thermostat | $10–$30 | $300–$382 |
| Gas igniter | $15–$40 | see no-heat band |
| Vent or duct work | — | $295–$450 |
| Control board | $100–$300 | $369–$612 |
| Any no-heat repair, all causes | — | $320–$438 |
| Diagnostic, nothing replaced | — | $99 |
Notice how narrow that right-hand column is. Whether the failed part costs $5 or $60 barely changes the invoice, because the visit and the labor dominate — which is exactly why confirming the diagnosis matters more than the price of the part. The control board is the only genuine outlier.

Safe to check yourself, no tools:
- Lint trap cleanliness
- Exterior vent cap for obstruction
- Circuit breaker (electric dryers use a double-pole breaker — one leg can trip while the other stays active, causing the motor to run but no heat)
- Gas supply valve position (gas dryers)
If those are all fine and the dryer still won’t heat, the problem is inside the heating circuit — and that’s where a technician earns the visit. Diagnosing which component failed takes a multimeter and partial disassembly, and several of the failures (thermal fuse, high-limit, and anything on a gas dryer) sit on the heat or gas circuit where a wrong move is a safety risk. The parts themselves are inexpensive at $5 to $60; the value is confirming the diagnosis so you replace the right part once. We carry thermal fuses, elements, igniters, and thermostats on the truck, so most no-heat calls are one visit.
Repair vs. Replace: When to Buy a New Dryer
The general appliance industry rule: if repair cost exceeds 50% of replacement cost, replacement becomes worth serious consideration.
A basic dryer costs $500–$800 new, and a mid-range unit $800–$1,200, before delivery, installation and haul-away of the old machine. Against that, using the 50% threshold:
- A no-heat repair at $320–$438 sits comfortably under half the cost of any mid-range replacement — worth doing
- A control board at $369–$612 on a machine over 10 years old is the case that warrants a replacement conversation
- Multiple simultaneous failures — heating element and drum bearing, for example — shift the math toward replacement
Age matters more than cost alone. A 4-year-old dryer with a blown heating element (a $305–$404 repair) should be repaired without hesitation. A 12-year-old dryer needing a control board that has already had one prior repair is a legitimate replacement candidate.
Dryer lifespan averages 10–13 years. Machines by Whirlpool, Speed Queen, and Maytag (under original ownership) have historically shown longer service lives in technician survey data. For a full breakdown, see how long dryers last.

Why does my dryer run but produce no heat?
The most likely cause is a blown thermal fuse, which interrupts the heating circuit permanently when the dryer overheats. The motor circuit is independent, so the drum keeps spinning normally. The next most common cause depends on dryer type: a failed heating element on electric dryers, or a failed igniter on gas dryers.
How much does it cost to fix a dryer that’s not heating?
Across 369 completed no-heat dryer repairs in our own records the ticket ran $320 to $438, median $375, with the part itself only $5 to $60 of that. By component: heating element $305–$404, thermostat $300–$382, thermal fuse $255–$435. The one outlier is a control board at $369–$612. If the fault is found and cleared without replacing anything, you pay the $99 diagnostic only.
Why is the labor so much more than the part?
Because the invoice is driven by the visit and the diagnosis, not the component. That is why a $5 thermal fuse and a $60 heating element land within about $100 of each other once installed. It is also the honest argument for doing the element yourself if your machine has rear panel access — the part is the cheap half of the job.
What’s the difference between a dryer that won’t heat and one that heats but won’t dry?
No heat at all points to the heating circuit — thermal fuse, heating element, or gas igniter. A dryer that gets warm but leaves clothes damp usually has a restricted vent or a partially failed element, which is a different diagnostic path. See our guide on a dryer not drying fast.
Can I reset a thermal fuse?
No. Thermal fuses are one-time devices — once blown, they must be replaced. Bypassing a thermal fuse is a fire hazard and voids manufacturer warranties. Before replacing one, the exhaust vent must be cleared, because a clogged vent is the root cause in most thermal fuse failures.
How long does a dryer heating element last?
Typically 8–12 years under normal use (5–7 loads per week). Overloading the dryer, running it with a restricted vent, or consistently using high-heat settings accelerates element degradation.
Is it worth repairing a dryer that doesn’t heat?
In most cases, yes. A no-heat repair runs $320 to $438 in our records, well under the 50% replacement threshold against a $500 to $1,200 new machine plus delivery and installation. The exception is a control board failure on a dryer already past ten years, especially one that has been repaired before.
How do I know if my dryer vent is clogged?
Drying time increases noticeably (a load that used to take 45 minutes now takes 75+), the dryer exterior feels hot to the touch, clothes come out hotter than normal, or the thermal fuse blows repeatedly after replacement. Any of these indicates restricted airflow. Vent and duct work in our records runs $295 to $450.
¿Por qué mi secadora no calienta?
Lo más común es un fusible térmico quemado, que corta el calor de forma permanente cuando la secadora se sobrecalienta — casi siempre por un ducto de ventilación obstruido. En secadoras eléctricas, la siguiente causa es la resistencia; en las de gas, el encendedor. Según nuestros propios registros, estas reparaciones cuestan entre $320 y $438 instaladas, con una mediana de $375. Atendemos secadoras el mismo día en Atlanta, Tampa, Jacksonville, Miami y Charlotte.
