Is your Amana dryer making a loud squeal? Our guide helps you diagnose & fix that screeching noise. Get your dryer running quietly again!
The Amana dryer utilizes a motor to rotate the drum via a belt and pulley system. Drum support rollers support the drum's weight. The MCU (Main Control Unit) controls the motor based on user settings and sensor inputs. Voltage is supplied to the motor through a 240V AC circuit. The motor then turns the drum and blower fan.
The homeowner reports a loud squealing or screeching noise coming from the Amana dryer during operation. The noise may be intermittent or constant, and may worsen as the dryer runs.
Disconnect power to the dryer at the breaker panel before performing any repairs. Dryer circuits operate at 240V AC, which can cause serious injury or death. Use proper lockout/tagout (LOTO) procedures.
Regularly clean the lint filter after each drying cycle. Clean the dryer vent duct at least once a year to prevent lint buildup and ensure proper airflow. Inspect and lubricate moving parts (rollers, idler pulley) annually with a high-temperature lubricant.
A common cause of squealing is a glazed drum belt. If the belt appears okay but still squeals, try lightly sanding the surface of the belt with fine-grit sandpaper to remove the glaze. Also, check the motor for any unusual smells. A burning smell indicates the motor is overheating and likely needs replacing. Service mode is accessed by pressing and holding the start button while pressing the temperature up button 3 times, then releasing the start button. This allows for diagnostic tests.
Follow-up Questions:
• What type of lubricant is recommended for the drum rollers?
Detailed answer: A high-temperature, non-staining lubricant specifically designed for appliance applications is recommended. Silicone-based lubricants are often a good choice.
• How do I properly tension the drum belt after replacement?
Detailed answer: Ensure the belt is properly routed around the drum and motor pulley. The idler pulley will automatically apply the correct tension. Check the dryer's service manual for specific belt routing diagrams.
• What is the typical lifespan of a dryer motor?
Detailed answer: A dryer motor typically lasts 8-12 years with regular use. However, factors like usage frequency, lint buildup, and overloading can shorten its lifespan.
