Safety first: Unplug the dryer before accessing the control panel or door switch.

Check user settings:
- Ensure the child lock is not active (refer to user manual for unlocking procedure).
- Confirm a valid program is selected and the time is not set to zero.
Door closure: Close the door firmly until it clicks; check for obstructions around the seal.
Door switch test: Press the door switch manually with the door open; if the display does not react, the switch may be faulty.
Start button: If other buttons respond but Start does not, the button or UI board may be defective and require replacement.

Note: Some models require pressing and holding Start for a second or two; check the user manual.

Dryer powers on but will not start when Start button is pressed; display may show normal time.
