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: most no-heat repairs run $100–$230. Check one thing first — the exhaust vent. A clogged vent is what blows the thermal fuse in the first place, 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 real repair cost ranges based on labor and parts 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: $5–$15 (OEM or aftermarket)
- Labor: $80–$150
- Total typical range: $100–$165
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.
- Part: $20–$60 depending on brand (Samsung, LG, and Whirlpool elements vary significantly)
- Labor: $100–$175
- Total typical range: $120–$230
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: $15–$40
- Labor: $100–$160
- Total typical range: $120–$200
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: $10–$30
- Labor: $80–$150
- Total typical range: $100–$175
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: $10–$25
- Labor: $80–$150
- Total typical range: $100–$165
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: $100–$300 (varies dramatically by brand and model)
- Labor: $100–$175
- Total typical range: $200–$475

Our technicians carry the most common thermal fuses, heating elements, and igniters on the truck — most repairs are completed same-day.
Schedule a TechnicianWhat You Can Check vs. What Needs a Technician
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 ($5–$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. A mid-range unit runs $800–$1,200. Using the 50% threshold:
- Repairs under $250–$400 are almost always worth doing on a mid-range machine
- Control board replacement ($200–$475 total) on a machine over 10 years old warrants replacement evaluation
- 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 ($120–$230 repair) should be repaired. A 12-year-old dryer with a failed control board ($400 repair) 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?
Most no-heat repairs run $100–$230: thermal fuse $100–$165, heating element $120–$230, gas igniter $120–$200, thermostats $100–$175. The outlier is a control board at $200–$475. In our own completed-job data the typical dryer repair runs around a $325 median.
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. The common causes — thermal fuse, heating element, igniter, cycling thermostat — cost $100–$230 to repair professionally, well under the 50% replacement threshold for any machine bought in the last 8 years. The exception is a control board failure on an older machine.
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. Professional vent cleaning typically runs $80–$180.
¿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. La mayoría de estas reparaciones cuestan entre $100 y $230.
