Dryer Running But Not Heating?
Here’s What’s Wrong

In most cases, yes. A dryer that runs but won’t heat almost always has a failed thermal fuse or heating element — both are relatively inexpensive repairs, typically $75–$350 total. The motor, drum, belt, and controls are all working, which means the machine itself is in good shape. You’re paying to restore the one system that’s failed, not to prop up a dying appliance.

The exception is if the dryer is over 10 years old, has had multiple repairs recently, or the diagnosis reveals a failed control board (which can push repair costs to $400–$500). In those cases, we’ll have an honest conversation about whether repair still makes financial sense.

Most no-heat repairs are completed in a single visit lasting 45 minutes to 2 hours. Thermal fuse and thermostat replacements are on the faster end. Heating element replacement varies depending on how accessible the element is on your specific model — some require removing the front or rear panel, which takes extra time.

We stock common thermal fuses, heating elements, and thermostats for Samsung, LG, Whirlpool, Maytag, GE, and Kenmore dryers. If your model requires a less common part, we may need to order it, but most popular parts are available same-day or next-day from California distributors.

A thermal fuse that blows repeatedly is a symptom, not the actual problem. The fuse is doing its job — protecting the dryer from overheating — but something is causing the dryer to overheat in the first place. The most common culprit is a clogged dryer vent line that restricts airflow and traps heat inside the drum.

Other causes include a dryer installed in a space without adequate ventilation, an unusually long or kinked vent duct run, or a damaged heating element that cycles too hot. If you’ve replaced a thermal fuse more than once, the vent system needs to be inspected and cleared from the dryer connection all the way to the exterior wall termination before installing another fuse.

Technically yes — the thermal fuse replacement itself is not complicated. It’s typically two screws and two wire connectors. However, there are a few things to keep in mind: First, you need to correctly identify the fuse’s location on your specific model (it varies significantly between brands). Second, and more importantly, you need to clear whatever caused the fuse to blow — almost always a clogged vent — or the new fuse will blow again quickly.

If you’re comfortable with basic appliance disassembly and already know your vent is clean, a DIY thermal fuse replacement is reasonable. If you’re unsure about the root cause, calling a technician often saves money in the long run — they’ll address both the fuse and the underlying cause in a single visit.

If the breaker appears set but the dryer still won’t heat, try flipping the breaker completely off and then firmly back on — sometimes a breaker that looks set is actually in a half-tripped position that doesn’t reset until fully cycled. If it trips again immediately when the dryer runs, the heating element may have a short that’s drawing excess current.

If the breaker holds and the dryer still won’t heat, the next most likely causes are the thermal fuse and the heating element itself. A technician can test both components in about 20 minutes with a multimeter and give you a definitive answer rather than having you guess-replace parts.

First, confirm which type of dryer you have. Look behind the machine: a gas dryer will have a flexible metal gas supply line connecting to a shutoff valve on the wall, in addition to a standard 120V outlet. Electric dryers plug into a dedicated 240V outlet (large 3- or 4-prong receptacle) with no gas line.

Gas dryers sometimes make a clicking or ignition attempt sound at the start of a heat cycle. If you hear clicking but no ignition, or briefly smell gas then nothing, the igniter or gas valve solenoid is the likely culprit. Electric dryers with heating problems are quieter — the drum just runs with no warmth.

Intermittent heat is a different problem from no heat at all. When a dryer heats briefly then cuts out, the most common causes are a cycling thermostat that’s failing (cutting heat too early), a partially blocked vent that causes the safety cutoff to trip after the dryer warms up, or a heating element with a partial break that only opens up when it expands from heat.

Intermittent problems are actually harder to diagnose than total no-heat because the components may test fine when cold. A technician experienced with this symptom knows to check the cycling thermostat, inspect the vent while the dryer is running, and look for element breaks under heat load rather than at room temperature.

Yes — not directly, but through the thermal fuse. When a vent is clogged, airflow is restricted, temperatures inside the drum and exhaust path climb higher than normal, and the thermal fuse trips as a protection mechanism. Once the thermal fuse blows, it stays blown permanently until replaced. The dryer keeps running with no heat.

This is the most important thing to understand about no-heat dryer repair: clearing the vent is not optional maintenance — it’s part of the repair. Replacing the thermal fuse without clearing the vent is a temporary fix that will fail again, sometimes within a few weeks. A properly done thermal fuse repair always includes vent inspection and cleaning.

In California, the total cost for a dryer not heating repair typically falls between $75 and $350, depending on what part has failed. A thermal fuse replacement runs $75–$150 all in. A heating element replacement is usually $150–$350. Thermostat and thermistor repairs fall in the middle of that range.

Labor rates in California tend to run higher than the national average — expect $90–$140/hour in most metro areas. Diagnostic fees range from $75–$130 and are usually credited toward the repair if you proceed. Gas dryer repairs for igniter or solenoid issues typically run $120–$320. Control board failures are the most expensive at $250–$500 and are sometimes not worth repairing depending on the dryer’s age and value.
