If your dryer won't start, first separate "no power" from "has power but will not run." Check the breaker, plug, outlet, door latch, control lock, cycle setting, start button, and whether the display shows an error code. Stop troubleshooting if you smell burning, see cord or outlet damage, the breaker trips again, or the drum will not turn after basic checks. Common repair causes include a failed door switch, thermal fuse, belt switch, start switch, motor, control board, or wiring problem.
Dryer has no lights and no display Likely cause: Tripped breaker, dead outlet, loose plug, power cord issue, or internal electrical failure. Homeowner action: Check the breaker once and confirm the plug is fully seated if safe.
Dryer powers on but will not start Likely cause: Door not latched, control lock, wrong cycle, start button issue, door switch, belt switch, or control problem. Homeowner action: Check lock settings, close the door firmly, and try a timed dry cycle.
Dryer clicks but drum does not turn Likely cause: Motor, relay, belt, roller, idler, or drum obstruction issue. Homeowner action: Stop repeated attempts and schedule diagnosis.
Dryer starts then shuts off quickly Likely cause: Motor overheating, blocked vent, sensor issue, small load sensing, or power interruption. Homeowner action: Let it cool, clean the lint filter, and check whether the vent warning appears.
Breaker trips when dryer starts Likely cause: Electrical short, motor problem, heater circuit issue, outlet problem, or installation fault. Homeowner action: Do not keep resetting the breaker.
Burning smell with no-start symptom Likely cause: Electrical overheating, belt issue, motor strain, lint buildup, or damaged wiring. Homeowner action: Stop using the dryer and call for service.
DIY difficulty: Low for checking the control lock, cycle selection, door closure, lint filter, visible plug position, and breaker status. Moderate for moving laundry, checking for overloaded or tangled items, and confirming whether a gas dryer outlet works with another small device.
Estimated homeowner check time: 10 to 35 minutes.
Tools needed: Flashlight, owner manual, phone for error-code photos, and a dry hand for checking controls. Do not use electrical test tools unless you are trained.
Safety risk: Medium to high. A dryer no-start problem can involve 240-volt power on electric dryers, gas connections on gas dryers, overheated wiring, moving parts, and lint-fire risk.
When to call a professional: Call when the dryer has power but will not run, the breaker trips again, the outlet or cord looks damaged, the drum is stuck, the dryer clicks without starting, the unit shuts off repeatedly, there is a burning smell, or any panel removal would be needed.
