Dryer not heating cycle runs — cycle runs

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Remove the load and check the control panel for an Air Only, Air Fluff, or other no-heat setting. If there is no gas odor, smoke, sparking, or damaged power connection, select a manual-approved heated timed cycle and observe from outside for a short period; do not open the cabinet or feel near a hot exhaust opening.

   Expected result: The selected cycle is air-only, the heated cycle produces warm exhaust, the drum tumbles but exhaust remains cold, or the dryer stops with an error or unusual odor.

   Next step: Choose the model-approved heated cycle only when safe and continue with filter, vent, load, and supply checks if the exhaust stays cold. Stop and arrange qualified appliance service for an error, unusual odor, smoke, sparking, or any unsafe power condition.

   Stop if: Do not keep running a heated cycle to force warmth, open the access panel, bypass a safety device, or place hands near hot air or energized components.

   Why this matters

   Why: An air-only selection explains no heat without a component failure, and warm exhaust means the heating system may be working while the load or airflow causes slow drying. Cold exhaust during a proper heated cycle confirms a heating or supply problem. A stop, error, odor, smoke, or spark raises the safety urgency.

2. Check 2

   Turn the dryer off and clean the lint screen according to the owner's manual. Inspect the accessible exhaust hose and outside hood for a visible kink, crushing, or lint obstruction; do not disconnect a difficult or hot vent connection. Check whether airflow at the outlet is weak compared with normal operation.

   Expected result: The screen is coated, the hose is kinked or crushed, the outside hood is blocked, airflow is weak, or the accessible exhaust path is clean and strong.

   Next step: Clean only the user-accessible screen and vent opening, restore a smooth vent route when it can be done without moving the appliance, and retest one normal load. Use qualified vent or appliance service for a hidden blockage, damaged vent, persistent weak airflow, or cold exhaust after cleaning.

   Stop if: Do not run the dryer with a missing lint screen, insert tools into the vent, remove the rear panel, or continue using it when lint buildup or overheating is suspected.

   Why this matters

   Why: Lint or restricted exhaust reduces airflow and can lengthen drying or cause heating protection to intervene. Normal accessible airflow makes a cycle, load, power or gas supply, heating element, burner, fuse, sensor, or control issue more likely.

3. Check 3

   Compare the symptom with the load and cycle: remove some items from a tightly packed drum, untangle bulky fabrics, and note whether clothes entered the dryer soaking wet. Confirm that the selected cycle is intended to heat and that the load has room to tumble; do not exceed the model's load guidance.

   Expected result: A smaller or drier load warms, only a large or tightly packed load stays cold or damp, or every load remains cold even with a proper heated cycle and normal airflow.

   Next step: Run one appropriately sized load only if the dryer produces heat and has no safety warning. If normal loads remain cold, keep the dryer off and continue to the supply check or arrange qualified service rather than repeatedly cycling wet laundry.

   Stop if: Do not use a dryer to compensate for soaking-wet loads, pack the drum tightly, or continue operation when the heating system appears completely inactive.

   Why this matters

   Why: A load that improves when reduced or spun drier can create a misleading slow-dry symptom by restricting circulation or adding excess moisture. Cold exhaust across normal loads points away from load size and toward power, gas, heating, safety, or control components.

4. Check 4

   Identify whether the dryer is electric or gas. From a dry, safe position, check that the plug and outlet show no burn marks or looseness and that the relevant breaker is not visibly tripped; for a gas dryer, verify only the accessible supply condition described in the owner's manual and do not adjust a gas fitting. Do not open the terminal box or remove a gas connection.

   Expected result: The electric dryer has a tripped or uncertain supply, the cord or outlet is hot or damaged, the gas supply appears unavailable, the breaker trips again, or the visible supply conditions are normal.

   Next step: Leave the dryer off and use a qualified electrician or appliance technician for a damaged cord, outlet, uncertain supply, repeated trip, or any internal electrical or gas diagnosis. If the visible supply is normal, the heating element, burner, fuse, sensor, or control needs qualified service.

   Stop if: Do not test voltage, reset a repeatedly tripping breaker, move wiring, open the terminal area, loosen gas fittings, or attempt this check if gas odor is present.

   Why this matters

   Why: An incomplete electric supply can leave the dryer running while the heater cannot operate, and a gas dryer can tumble without producing heat when its fuel supply is unavailable. Damage, repeated trips, or uncertainty indicate an electrical or gas-service boundary rather than a user adjustment.
