First identify whether the dryer is electric, gas or a different drying system, then distinguish no heat from warm-but-damp laundry. This hub routes those observations to the relevant checks. Exact model settings and diagnostic controls belong on the linked model pages.
Brand-level navigation and symptom classification. Exact-model pages own their documented controls and access procedures.
Stop for smoke, burning smells, abnormal heat or repeated breaker trips. Let the dryer cool before cleaning. Do not expose wiring, bypass interlocks or work on gas components. If gas is smelled, leave and call the utility or emergency services from a safe location.
Choose the observed outcome
A lost heating supply and a fault inside the appliance can both leave a turning drum cold. The useful discriminator for a homeowner is the pattern: no heat at any point versus warmth with poor drying. Neither a working display nor an audible motor clears the supply. Record that distinction before paying for a heater; the next professional test should establish where the failure actually sits.
Start with the relevant branch
No heat versus slow drying
A cold heated cycle, an early automatic ending and a warm damp load are different observations. Note selected cycle, fuel type, code and whether the drum turns. Do not treat a working motor as a complete supply test.
Electric and gas boundaries
Keep electrical measurements and gas-system diagnosis with qualified professionals. If you smell gas, leave without operating nearby switches and call the utility or emergency services from a safe location.
Resetting does not repair airflow or a heater
Preserve codes before any permitted power interruption. A reset cannot remove a physical restriction, and a returning warning requires diagnosis rather than another repeated reset.
Go to the exact problem
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
