If your dryer is not heating, spinning, or appears to be broken, it's important to diagnose the issue before attempting any repairs. Start by checking the power supply to ensure the dryer is plugged in and the circuit breaker hasn't tripped. If the power is fine, inspect the door latch; a malfunctioning latch can prevent the dryer from operating. Additionally, examine the lint filter and vent for clogs, as poor airflow can cause heating issues. If these steps don't resolve the problem, it may be necessary to test the heating element or thermostat for faults. For more complex repairs, consulting a professional technician might be the best course of action to ensure your dryer is safe and functional again. Regular maintenance can also help prevent future issues and extend the life of your appliance.
