No-heat diagnostic
The dryer runs, but clothes come out wet. The cause is almost always one of six components.
A dryer that tumbles normally but produces no heat is the single most common dryer service call we make. The drum motor is fine, the controls work, the timer counts down. But the load comes out cold and damp. The cause is almost always one of six components, and the diagnostic order matters because replacing the wrong component first costs you parts money and gets you the same callback in two weeks.
Our techs service no-heat dryers across LA, Orange, Ventura, San Bernardino, and Riverside. Both gas and electric, all major brands: Whirlpool, GE, Samsung, LG, Maytag, Electrolux, Bosch, Frigidaire, KitchenAid, Miele, Thermador, Speed Queen, and others. The diagnostic sequence is the same across brands: vent first, thermal fuse second, heating components third. Most no-heat calls resolve at the thermal fuse plus vent step.
$89 residential diagnostic, waived with repair. BHGS #A49573. EPA 608 Universal #1346255700410. BBB A+. Phones answered 24/7. Vent inspection is included on every no-heat call, not a separate trip charge.
Architecture
Gas dryer vs electric dryer: different components, same diagnostic logic.
The dryer architecture matters because the failed component is different. The diagnostic order is the same, but the parts and prices differ.
Electric dryer no-heat
Most LA homes built before 2010 have electric dryers. The heating system is a coiled nichrome heating element wrapped around the back of the drum, plus a thermal fuse, a high-limit thermostat, and a cycling thermostat. Failure modes by frequency: thermal fuse blown (year 4 to 10, almost always vent-related), heating element burned out (year 8 to 12), high-limit thermostat tripped (rare on its own, usually paired with vent restriction). Replacement parts: thermal fuse $35 to $65, heating element $145 to $245, high-limit thermostat $45 to $85.
Gas dryer no-heat
Newer LA construction (especially condos and townhomes built post-2015) increasingly has gas dryers because they're cheaper to operate. Gas dryer adds three components: gas valve coils (electromagnetic solenoids that open the gas valve, year 5 to 9 typical wear), an igniter (hot-surface igniter on most modern dryers, year 5 to 9), and a flame sensor (rare failure but happens). Failure modes by frequency: igniter failed (most common gas no-heat call), gas valve coils degraded (often paired with igniter failure), thermal fuse blown (same root cause as electric, vent restriction).
The vent is the unstated cause
About 70% of no-heat repairs we make trace back to a restricted dryer vent at root cause. The vent restriction overheats the dryer cabinet, which trips the thermal fuse or stresses the heating element. Replacing the failed part without clearing the vent guarantees the same failure within weeks. We inspect and clear the vent on every no-heat call. This is included in the repair labor, not a separate charge.
Diagnostic order
How we diagnose no-heat in 20 to 30 minutes.
- Vent airflow check (first, before any electrical testing). We measure airflow at the exterior vent cap with an anemometer. Below 1,500 feet per minute means the vent is restricted. Most LA homes have vent runs of 8 to 25 feet through interior walls and they accumulate lint at predictable rates.
- Thermal fuse continuity test. Multimeter on the fuse leads. Open circuit means blown. About 60% of no-heat calls have a blown thermal fuse, almost always paired with a vent issue from step 1.
- Heating element ohm test (electric dryers). Resistance should read 8 to 15 ohms depending on model. Open circuit means burned out. About 25% of no-heat electric dryer calls.
- Igniter ohm test (gas dryers). Hot-surface igniter resistance 50 to 400 ohms depending on model. Open circuit means burned out. The dominant failure mode on gas no-heat.
- Gas valve coil ohm test (gas dryers). Two coils, primary and secondary. Both must test in spec for the gas valve to open.
- High-limit thermostat continuity test. Closed at room temperature. Open means tripped, almost always vent-related.
Once the failed component is identified, we clear the vent, replace the failed part, and run a heat-cycle test to confirm the dryer reaches operating temperature within 5 minutes. The whole repair typically runs 60 to 90 minutes including the vent clearance.

Brand notes
No-heat patterns by brand.
- Whirlpool, Maytag, KitchenAid (Whirlpool family). Thermal fuse plus vent issues dominant. F01 control board failure rare on no-heat calls (more common as a different symptom). Common parts on the van.
- GE. Heating element burnout at year 8 to 12 typical. Hot-surface igniter on gas models is the year 5 to 9 wear item.
- Samsung. DV series thermal fuse failures common, almost always vent-related. Heating element at year 8 to 12.
- LG. DLE and DLG series solid reliability on heating systems. When no-heat happens it's usually thermal fuse plus vent.
- Electrolux, Frigidaire (Electrolux family). Anderson SC parts cross-fit between brands. Heating element pattern similar to GE.
- Bosch (USA dryer line plus 800 Series condenser). European architecture is different. Condenser dryers have a separate failure tree we cover separately.
- Miele, Thermador. Premium tier. Heating components last longer (year 12+) but parts cost more.
- Speed Queen, Frigidaire commercial-grade. Built tougher than mid-tier residential. Heating elements last 12 to 15 years typical.
FAQ
Dryer no-heat questions.
My dryer runs but no heat. What's the most common cause?
On an electric dryer, the two most common causes are a blown thermal fuse (year 4 to 10 typical, almost always triggered by a restricted vent rather than a true equipment failure) and a burned-out heating element (year 8 to 12). On a gas dryer, the most common cause is a failed igniter (year 5 to 9), followed by gas valve coils, then a blown thermal fuse. We test all of these in sequence before quoting parts.
Why does the thermal fuse keep blowing?
The thermal fuse is a safety device that cuts power to the heating circuit when the dryer overheats. Repeated thermal fuse failures almost always mean restricted airflow through the vent, which causes the dryer cabinet to overheat. Replacing the fuse without clearing the vent guarantees another blown fuse within weeks. We inspect and clear the vent on every no-heat call as part of the repair, not as a separate trip charge.
Do you service gas dryers? What's different about them?
Yes. Gas dryers add three components that electric dryers don't have: gas valve coils (electromagnetic solenoids that open the gas valve), an igniter (hot-surface or spark depending on age), and a flame sensor. When a gas dryer won't heat, we test those components in addition to the standard thermal fuse and high-limit thermostat. Gas dryer no-heat repairs typically run $145 to $285 for the ignition system, $185 to $285 for gas valve coils.
How do I know if it's the heating element or the thermal fuse?
Both produce the same symptom (dryer runs, no heat), but they fail differently. Thermal fuse failure is sudden: the dryer was working last load, no heat this load. Heating element failure is more often gradual on coil-type elements: clothes take longer than usual, then very long, then no heat at all. Both require a multimeter ohm test for confirmation, which we do at the diagnostic visit. Don't replace either part on guess.
What's the typical cost of a no-heat repair?
On electric dryers: thermal fuse plus vent inspection $145 to $245. Heating element replacement $285 to $425. Both at year 10+ if both have failed: $385 to $525. On gas dryers: igniter replacement $145 to $245. Gas valve coils $185 to $285. Thermal fuse plus vent on a gas dryer same as electric. The $89 diagnostic is waived when you approve the repair.
Should I replace my dryer instead of repairing the heating element?
Mid-tier dryer (under $700 retail) at year 10+ with major heating element failure: replacement is often the right call, especially if the matching washer is also aging. Premium tier (Miele, Bosch, LG WashTower, Samsung Bespoke) almost always favors repair through year 12 because replacement runs $1,500 to $3,000+ and the chassis outlasts the heating element. We do the math with you on-site.
