Dryer won’t start? Check the door, controls, and power

A blocked door latch, locked control, incomplete Start command, wrong cycle, or tripped breaker can stop a dryer without proving the motor or control has failed.

Short answer: Make sure no clothing is caught in the door, close it until it latches, disable Control or Child Lock using the exact model manual, select a normal timed or sensor cycle, and press or hold Start as instructed. Confirm the plug is fully seated and reset the correct dryer breaker once. If the breaker trips again, the cord or outlet is hot or damaged, the drum only hums, an error returns, or diagnosis requires opening the cabinet, leave the dryer off and call a qualified technician or electrician.

Why it matters

A dryer must detect a closed door, accept the selected control state, and receive the correct power before the motor can run. Whirlpool lists the Start command, touch controls, breaker, door latch, cycle, and Control Lock as first checks. Samsung likewise recommends checking the displayed error, Child Lock, door, and whether a timed cycle actually begins counting down. If those checks do not restore operation, the fault may involve a door or belt switch, thermal protection, motor, control, or power supply that needs qualified diagnosis.

Safe checks, step by step

1
Stop the dryer and remove or redistribute the load. Make sure no clothing is caught between the door and cabinet, then close the door firmly enough to engage the latch. Do not slam the door, force a damaged latch, tape the door shut, or bypass the door switch.
2
Read the display and note any error code or illuminated lock symbol. With dry hands and a dry control panel, disable Control Lock or Child Lock only by following the instructions for your exact model. Do not guess at hidden service-button combinations.
3
Select a normal Timed Dry or sensor cycle rather than a wrinkle-control, delay, pause, or air-only option. Press and hold Start for the time stated in the owner’s manual. Watch whether the timer begins counting down, the drum moves, or an error appears.
4
Listen once for a click or hum and record what happens. If the motor hums without turning the drum, stop the attempt instead of repeatedly pressing Start. Note the model number, error code, sounds, and whether the interior light responds to the door for the technician.
5
With the dryer off and your hands dry, inspect only the visible plug, cord, and outlet. Confirm the plug is fully seated if it is safely accessible. Stop for looseness, discoloration, melting, scorching, unusual heat, or damage; do not move a gas dryer, remove a terminal cover, or open the cabinet.
6
If the owner’s manual allows it and the electrical panel is safely accessible, reset the correctly labeled dryer breaker once by moving it fully off and then on. Electric dryers commonly use a double-pole breaker. Never remove the panel cover or touch wiring, and leave the dryer off if the breaker trips again.

Stop and call a professional if

You smell burning or gas, see smoke or sparks, or find a hot, loose, scorched, melted, or damaged plug, cord, or outlet
The dryer breaker trips again, will not remain set, or another electrical problem affects the outlet or panel
The dryer hums or clicks but the drum does not turn, a door or belt error returns, or the door will not latch securely
The dryer starts only while you push on the door, the controls flicker or reset, or the drum can run with the door open
The appliance is gas-fired and access would require moving it, disconnecting gas, or investigating any fuel or ignition component
Diagnosis would require opening the cabinet or terminal block, testing energized parts, replacing internal wiring, or bypassing a door, belt, thermal, or other safety device
