Lack of heat: If your dryer isn't producing enough heat or is not heating at all, it could be due to a faulty heating element, a malfunctioning thermostat, a blown thermal fuse, or a problem with the gas or electric power supply.

Drum not spinning: If the drum of your dryer isn't spinning, it may be due to a broken belt, a malfunctioning motor, or a defective roller or idler pulley.

Failure to start: When a dryer doesn't start when you press the start button, it may be caused by a broken door switch, a faulty start switch, a blown thermal fuse, or issues with the power supply.

Error codes: Some modern dryers display error codes to indicate specific problems. These codes can vary depending on the dryer's make and model. Consulting the owner's manual or contacting the manufacturer can help decipher the meaning of these error codes.

Noisy operation: Dryers can become noisy over time due to worn-out drum bearings, damaged belts, defective rollers, or a faulty motor. These components may need to be replaced to restore normal operation.

Excessive drying time: If your clothes take longer than usual to dry, it could be a sign of a clogged vent or exhaust system. Insufficient airflow reduces the dryer's efficiency and prolongs drying times.
