If you replaced a snapped belt on a dryer and it now barely spins or stops when there are more than a few clothes, there could be several possible causes:
Belt Tension: Check the tension of the newly installed belt. It's possible that the belt is not properly tensioned, causing it to slip or not provide enough power to rotate the drum effectively. Ensure that the belt is properly aligned and tightened according to the manufacturer's instructions.
Motor Issues: The motor of the dryer might be malfunctioning or not generating enough power to rotate the drum. This could be due to a faulty motor capacitor, worn-out motor bearings, or other motor-related issues. A defective motor may need to be repaired or replaced by a professional.
Drum Alignment: Verify that the drum is properly aligned within the dryer. If the drum is not aligned correctly, it can cause excessive friction, making it difficult for the motor to rotate it smoothly. Adjust the drum if necessary to ensure it rotates freely.
Obstruction or Excessive Load: Check for any obstructions in the drum, such as foreign objects or lint buildup, which can impede rotation. Additionally, overloading the dryer with too many clothes can put strain on the motor and cause it to struggle or stop. Ensure the drum is clear of obstructions and avoid overloading the dryer.
Idler Pulley or Drum Roller Issues: The idler pulley or drum rollers could be worn out or damaged, resulting in reduced rotation or difficulty in turning the drum. Inspect these components for signs of wear or damage and replace them if necessary.
If troubleshooting these common causes does not resolve the issue, it's advisable to consult a professional appliance repair technician. They have the expertise to diagnose and address more complex problems with your dryer.
