What is a common symptom indicating a malfunctioning dryer?

A common symptom indicating a malfunctioning dryer is that it may not heat or tumble as expected. This is a critical issue because the primary functions of a dryer are to heat the air to dry clothes and to tumble them for even drying. When a dryer is not heating, it can be due to various reasons, such as a faulty heating element, a broken thermostat, or an issue with the power supply. On the other hand, if it is not tumbling, it could indicate problems with the drive belt, motor, or drum support rollers.

Identifying the issue early is essential for effective troubleshooting and repair. When a dryer does not perform either of these functions, it may result in damp clothes or potentially cause further damage if left unaddressed. This symptom often requires immediate attention to analyze and fix the underlying cause, ensuring the dryer operates efficiently again.
