Samsung Dryer: not starting
What is this symptom?
Is your Samsung dryer not starting? This common issue may manifest as no power or as the dryer powering on without spinning the drum. Several factors could be causing this problem, including power supply issues, control settings, or mechanical failures. Identifying the root cause can help you address the problem effectively.
