Samsung Dryer: not operating
What is this symptom?
Is your Samsung dryer not operating? If your dryer won't start or run any cycle, you're likely facing issues with the power supply, door switch, or child lock. Understanding these common causes can help you troubleshoot effectively and get your appliance back in working order.
Important Tips for Samsung Models
- Child Lock feature can prevent start even when controls seem functional; disabling it via specific button combo or power reset may allow operation
