If your dryer has stopped spinning but still makes noise and heats up, there could be a few potential reasons for this issue:
Broken Drive Belt: One common reason for a dryer to stop spinning is a broken or worn-out drive belt. The drive belt connects the motor to the drum, allowing it to spin. When the belt breaks or becomes loose, the motor can still run, making noise, and the heating element can still function, but the drum won't spin.
Faulty Motor: The dryer motor may have malfunctioned or burned out, preventing the drum from spinning. In this case, the motor may still produce noise, and the heating element can still work, but the drum won't move.
Defective Idler Pulley: The idler pulley is responsible for keeping tension on the drive belt. If the idler pulley is faulty or misaligned, it can cause the belt to slip off or become loose, resulting in the drum not spinning even though the motor is running.
Jammed Drum: Something might be obstructing the drum's movement, preventing it from spinning freely. This could be caused by a foreign object stuck between the drum and the dryer's walls or a malfunctioning roller or support wheel.
Worn Drum Rollers or Glides: The drum rollers or glides support the drum's movement. If they become worn or damaged, they can impede the spinning motion.
Broken Start Switch: The start switch is responsible for initiating the dryer's motor when the dryer door is closed. If the start switch is faulty, the dryer may produce noise and heat up, but the drum won't spin.
It's important to address the issue promptly to avoid further damage and to ensure your dryer operates safely and efficiently. If you're not familiar with dryer repairs, it's recommended to contact a qualified appliance technician to diagnose and fix the problem for you. They can accurately identify the issue and perform any necessary repairs or replacements to get your dryer working properly again.
