Dryer tumbles but won’t heat? Check the cycle, lint screen, and breaker

A no-heat dryer can still tumble when an Air Only setting is selected, airflow is restricted, or part of an electric dryer’s 240-volt supply is interrupted.

Short answer: Stop immediately for smoke, a burning smell, unusual heat, sparking, a hot or damaged cord or outlet, or any gas odor. Otherwise, confirm the dryer is actually tumbling, identify whether it is electric, gas, or heat-pump from the exterior label, and select a normal heated or Timed Dry cycle rather than Air Only, Air Fluff, or another no-heat setting. Clean the lint screen and check only the safely accessible exterior exhaust hood on a vented model. For an electric dryer, a partially tripped two-pole breaker can let the drum run without powering the heater; reset the correctly labeled dryer breaker once only if the panel is dry, intact, and safely accessible. If heat does not return, the breaker trips again, airflow is weak, or the dryer is gas or heat-pump and still will not heat, stop and call a qualified technician. Never open the cabinet, test voltage, replace a heating component, or operate gas controls.

Why it matters

The drum motor and heating system do not always lose power together. Whirlpool and GE explain that an electric dryer may tumble on partial power but needs its full 208/240-volt supply to heat. Samsung also lists the selected cycle, electrical supply, gas installation, and exhaust system among the reasons clothes may not dry. Airflow still matters even when the complaint is “no heat”: restricted exhaust can cause overheating or safety shutdowns rather than simply longer cycles. The U.S. Fire Administration advises plugging washers and dryers directly into wall outlets, cleaning the lint filter every use, and cleaning dryer vent ductwork regularly to reduce fire risk.

Safe checks, step by step

1
Check for a hazard before testing. Stop using the dryer for smoke, sparks, scorching, a burning or electrical odor, unusual cabinet heat, a hot or damaged plug, cord, outlet, or breaker, melted vent material, or any gas odor. For a suspected gas leak, do not touch switches, plugs, appliances, or phones inside; get everyone outside and call 911 or the gas utility from a safe location.
2
Confirm the exact symptom and dryer type without removing a cover. Note whether the drum turns, whether an error code appears, and whether the exterior label or manual identifies the unit as electric, gas, heat-pump, or ventless. A heat-pump dryer normally uses lower temperatures and needs model-specific filter and heat-exchanger care, so compare its behavior with the manual rather than judging by how hot the drum feels.
3
Review the cycle before one brief test. If the owner’s manual permits it, use an empty dryer on a heated Timed Dry setting for about five minutes—not Air Only, Air Fluff, Refresh, or another unheated option. Cancel the test if there is an odor, unusual sound, error code, weak airflow, or abnormal heat. Do not run repeated cycles to prove the problem.
4
After the dryer stops and cools, remove and clean the owner-accessible lint screen exactly as the manual directs. Look for lint or fabric-softener residue that blocks the mesh. Wash the screen only if the manufacturer permits it, let it dry fully, and reinstall it correctly. Never reach past the screen opening, remove a grille, or use the dryer without the screen.
5
For a vented dryer only, inspect the visible transition duct and exterior exhaust hood without moving the appliance, climbing, opening walls, or entering an attic or crawlspace. During the single test, observe from outside whether the flap opens and airflow is noticeable. Stop if the duct is crushed, detached, made of unsafe material, or inaccessible; professional vent service is safer than moving a gas dryer or opening concealed ductwork.
6
For an electric dryer only, check the home panel if it is dry, undamaged, clearly labeled, and safely accessible. Reset the correctly labeled two-pole dryer breaker once by moving it fully off and then on. Never remove the panel cover, replace a fuse, test the receptacle, touch wiring, or repeat the reset if it trips again. If the dryer still tumbles without heat, record its model, fuel type, cycle, error code, airflow observation, and breaker result for the technician.

Stop and call a professional if

You smell gas—leave immediately without operating switches, plugs, appliances, or phones inside, then call 911 or the gas utility from outside
There is smoke, sparking, scorching, a burning-electrical odor, unusual cabinet heat, or a hot, loose, buzzing, melted, or damaged plug, cord, outlet, breaker, or vent
The dryer breaker trips again, a fuse is blown, the panel is wet or damaged, or checking the supply would require a meter, receptacle testing, wiring access, or panel-cover removal
Outdoor airflow is weak, the exterior flap does not open, an airflow or temperature error returns, or the vent is crushed, detached, concealed, or requires moving the dryer to reach
A gas or heat-pump dryer tumbles but does not heat after the correct cycle, owner-accessible filters, and normal exterior conditions are checked
Diagnosis would require opening the cabinet, bypassing a switch or thermal device, replacing a fuse, element, igniter, valve, sensor, thermostat, control, or power cord, repairing gas controls, or working on energized circuits
