How much does it cost to fix a dryer that won't heat?

The short answer

If your dryer tumbles but blows cold air, the fix usually costs $20 to $100 doing it yourself or $150 to $550 with a pro.

The exact number depends on which part died and whether you've got gas or electric.

Most no-heat problems come down to a handful of cheap parts: a thermal fuse, a heating element, or (on gas) an igniter. None of those are expensive on their own.

The bigger cost driver is diagnosis and labor if you call someone out. A service call alone runs $80 to $150 in most US markets in 2026 before any parts.

What it costs in 2026

Here's the honest breakdown by part, DIY versus calling someone.

Thermal fuse: $10 to $20 in parts DIY, or $130 to $220 with a pro after the service call and labor.

Heating element (electric): $30 to $90 DIY, or $200 to $400 installed. Elements are bulky and shipping can add a few bucks.

Igniter (gas): $20 to $50 DIY, or $180 to $350 installed.

Gas valve coils: $15 to $40 DIY, or $180 to $350 installed.

Thermostat or thermistor: $10 to $30 DIY, or $150 to $280 with a pro.

Control board: $150 to $300 in parts, and honestly not a great DIY gamble because it's easy to misdiagnose. Figure $350 to $550 installed.

Add a professional vent cleaning if your fuse blew from a clog: $100 to $200 on its own, less if bundled with the repair.

• Service call fee alone: $80 to $150
• Cheapest common fix (thermal fuse DIY): about $15
• Most expensive common fix (control board, pro): up to $550
• Vent cleaning add-on: $100 to $200

How we put this together

These cost ranges come from real 2026 US repair pricing: parts pricing from major appliance parts suppliers and labor from independent and regional service rates.

The diagnostic order reflects how field techs actually work a no-heat call, cheapest and most likely first.

Prices vary by region, brand, and how hard your dryer is to access. A stacked unit in a hall closet costs more to service than a standalone in a basement.

Use these numbers as a planning range, not a quote. Your local tech's service fee and parts markup set the final bill.

What's actually wrong

On electric dryers, the thermal fuse is the usual suspect. It's a one-time safety device that blows when the dryer overheats, and once it's gone the heat is done.

The heating element is the next most common. It's a coil that either cracks with age or burns through, leaving you with air but no warmth.

Gas dryers play by different rules. They rely on an igniter that glows red-hot to light the gas, plus valve coils that release the fuel. Either failing means no flame.

Don't overlook the breaker. Electric dryers need both 120V legs of a 240V circuit, and losing one keeps the motor running while the element gets nothing.

Thermostats and thermistors round out the list. They regulate temperature, and when one fails open the heat circuit never closes.

• Blown thermal fuse: most common, usually caused by a clogged vent
• Bad heating element (electric): second most common
• Failed igniter or gas valve coils (gas)
• Lost breaker leg (electric)
• Faulty thermostat or thermistor

How to track it down

Start with the free checks. Confirm the drum spins, then reset the breaker and inspect the vent. You'd be surprised how often one of those solves it.

If the vent's clear and the breaker holds, it's time to open the machine. Unplug it first, every time.

Grab a multimeter. Continuity testing is how you tell a good part from a dead one, and it takes the guessing out of the job.

Test the thermal fuse first since it's the most likely and the cheapest. Open circuit means replace it.

For electric dryers, test the element next. It should read around 10 to 15 ohms. An open reading confirms a burnout.

Gas owners: run the dryer with the panel off and watch the burner. If the igniter glows but no flame follows, the valve coils are the problem. If it never glows, the igniter's open.

Whatever you replace, run a full test cycle on high and feel the exhaust after five minutes. Warm air is your confirmation.

Should you do it yourself

A thermal fuse or heating element swap is genuinely DIY-friendly. If you can unplug the machine, remove a back panel, and use a multimeter, you can handle it.

The parts are cheap and the repair is mechanical, not delicate. Most people finish in under an hour once they have the part.

Gas dryers raise the stakes. You can diagnose an igniter or coil yourself, but if the gas valve connection is involved and you're not confident, pay a pro. The service fee is cheaper than a mistake.

Control boards are the one part I'd almost never buy on a guess. They're expensive, non-returnable once installed, and frequently blamed for problems a $15 thermostat actually caused.

How long can you put it off

A no-heat dryer isn't an emergency in the way a leaking water heater is. You won't wake up to a flooded room.

But don't sit on it for weeks. If the cause is a clogged vent (and it often is), that lint is a fire hazard the whole time it's building up.

Gas models deserve a little more urgency. A failing valve or igniter should get looked at soon rather than run repeatedly.

Practically speaking, the biggest cost of waiting is piles of damp laundry and the temptation to run cold cycles that accomplish nothing.

Safety ground rules

Power and gas both demand respect here. Treat every internal check like the machine could hurt you, because it can.

For electric: unplug first, and if you're testing the breaker, use the full double-pole switch.

For gas: shut the supply valve before opening anything, and never hunt for a leak with a match or lighter. Use soapy water on connections instead.

Let hot parts cool. The element and burner area hold heat long after the cycle ends.

The bottom line

A dryer that won't heat is one of the more fixable appliance problems out there.

Odds are good it's a cheap part and a clogged vent, both of which a careful homeowner can handle in an afternoon.

Test before you buy, clean that vent while you're in there, and only reach for a pro when gas work or a control board enters the picture.

Do it right once and you'll likely get years more out of the machine.
