Dryer Won't Start
A dryer that will not start can have a simple cause, such as an unlatched door, a control-lock setting, or a tripped breaker. It can also have a failed door switch, broken belt switch, thermal fuse, start switch, motor, or control board. Begin with the safe external checks. Do not open the cabinet, bypass a door switch, or repeatedly reset a breaker. Unplug the dryer before cleaning around the door opening or moving it, and call for service if there is a burning smell, heat, smoke, damaged cord, or a breaker that trips again.

Common Symptoms
- Dryer display lights up but the drum will not start
- Pressing Start produces a click, hum, or no response
- Dryer stops immediately after Start is pressed
- Door must be pushed hard before the dryer will run
- Dryer has no display or appears completely dead
Most Likely Causes
- 1
Door Not Latching or Failed Door Switch
The dryer will not run unless the door switch confirms the door is closed. A misaligned strike, lint-packed latch area, or worn switch can prevent the start circuit from closing.
- 2
Control Lock, Cycle Setting, or Start Sequence
Some models require holding Start for several seconds and will ignore input while Control Lock is on. A delayed-start setting or an incomplete cycle selection can also look like a failure.
- 3
Power Supply or Breaker Issue
An electric dryer can lose one leg of its 240-volt supply, while a gas dryer still needs a working 120-volt outlet. A tripped breaker, loose cord, or damaged receptacle needs safe evaluation.
- 4
Failed Internal Start Component
A thermal fuse, belt switch, start switch, motor, wiring connection, or electronic control can stop the dryer from starting. These require model-specific testing after power is disconnected.

Quick DIY Checks
ELECTRICAL WARNING: An electric dryer uses 240 volts. Do not remove panels, test live wiring, bypass the door switch, or touch a hot, damaged, or loose outlet. Leave a repeat-tripping breaker off.
FIRE WARNING: Stop using the dryer and disconnect power if you smell burning, see smoke, find scorched wiring, or hear loud electrical buzzing. Have the appliance and circuit inspected before reuse.
If a gas dryer will not start and you smell gas, do not operate switches or use flames. Leave the area and follow your gas utility's emergency instructions.
- 1Open and close the door firmly. Remove visible lint from the latch area with the dryer unplugged; do not insert tools into the door-switch opening or defeat the switch.
- 2Confirm a cycle is selected, Control Lock and Delay Start are off, and hold the Start button for the time shown in the owner's manual.
- 3Check whether the display or drum light works. Inspect the power cord and outlet from the outside only for heat damage, loose fit, scorching, or a burning odor. Stop immediately if any are present.

Repair vs Replace
Most no-start faults are repairable and are less expensive than replacing a recent dryer. Consider replacement only when an older unit needs a motor or control board alongside major drum, bearing, or cabinet damage.
Est. Repair Cost
$110–$420 for a door switch, thermal fuse, belt switch, start control, or motor diagnosis
Est. Replacement Cost
$600–$1,400 for a comparable dryer

Frequently Asked Questions
- Why does my dryer click but not start?
- A click can come from the control or relay, but the dryer may still have an open door switch, belt switch, thermal fuse, motor, or power-supply problem. Do not keep pressing Start repeatedly.
- Can a dryer breaker be half tripped?
- Yes. A double-pole breaker can appear on while one side is tripped. Reset it fully off and then on once only if there is no damage or burning smell. A repeat trip needs professional diagnosis.
