Dryer drum won't turn

Issue description:

The reasons listed below when the dryer drum does not turn are listed from most likely to least likely. Check or test each cause, starting with the most probable cause.

Drive Belt

Drum Support Roller

Drum Roller Axle

Drum Bearing

Drum Support Roller and Axle

Drum Guiding Support

Chain pulley

Carrier support (plate) or drum panel

Drive motor

Dryer drum won't turn

Solution:

The drive belt is a very long, thin belt wrapped around the tumble dryer, idler, and then around the drive motor pulley. Over time, the belt can wear out from normal use. If the belt is damaged, the dryer will not rotate. To quickly determine if a belt is damaged, go to the dryer and turn the drum by hand. If the drum turns very easily, the belt is likely damaged. Then check the belt to make sure it is damaged, in which case replace it.

One or more drum support rollers may be worn out. Most dryers have two drum support rollers on the back of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must rotate freely for proper operation. If the rollers do not rotate freely, the motor will be overloaded and the dryer will stop. If the drum rollers are worn out, they will stop rotating freely. To determine if the idler rollers are worn, remove the belt from the dryer and try manually turning the drum. If the drum turns hard, check the support rollers for wear. If one or more of the rollers rotate slowly, we recommend replacing all rollers at the same time for preventive maintenance (The roller shaft can often be reused if it is in good condition. Clean the shaft thoroughly before installing new rollers.)

One or more of the drum roller axles may be worn out. Most dryers have two drum support rollers on the back of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must rotate freely for proper operation. If the roller shafts are worn out, the rollers can turn hard, overloading the motor and stopping the dryer. To determine if the drum roller axles are worn, remove the belt from the dryer and try manually turning the drum. If the drum does not rotate freely, check the support rollers for wear. If the rollers rotate freely without wobbling, then the axles are in order. If the roller loosens and / or does not rotate properly, we recommend replacing all pins and rollers as a preventive measure.

The drum bearing supports the rear of the tumble dryer. Over time, this bearing will wear out and this can overload the motor, causing the dryer to stop mid-cycle. To determine if the drum bearing is vibrating, remove the dryer belt and try turning the drum by hand. If the drum rotates freely, it is unlikely that the drum bearing is worn. If the drum makes a squeak or rattling sound when turning and / or is difficult to turn, check the drum bearing and replace it if necessary.

One or more axles of the drum support roller may be worn out. Most dryers have two drum support rollers on the back of the drum, and some dryers have two more rollers supporting the front of the drum. The rollers must rotate freely for proper operation. If the axles of the support drum are worn out, the rollers will not be able to rotate freely, which will overload the motor and stop the dryer. To determine if the drum roller axles are worn, remove the belt from the dryer and try manually turning the drum. If the drum turns hard, check the axles for wear. If the rollers rotate freely and do not dangle from side to side, then the axles do not need to be replaced. If the roller loosens and / or does not rotate properly, we recommend replacing all axles and rollers as a preventive measure.

The guiding drum support supports the front of the tumble dryer. Over time, this support will wear out and this can overload the motor, causing the dryer to stop mid-cycle. To determine if the drum support is damaged, remove the dryer belt and try turning the drum by hand. If the drum rotates freely, it is unlikely that the drum guide support is worn. If the drum makes a squeak or squeak when turning and / or is difficult to turn, check the drum guide support and replace if necessary.

Inspect the chain pulley for the dryer drum belt and make sure it rotates freely on the shaft. If the chain pulley is stuck, worn or damaged, we recommend replacing the drum drive belt in addition to replacing the chain pulley.

If the dryer stops rotating during the cycle, then one or more of the drum supports (plates) may be worn out. The drum carrier guides are small plastic parts that support the front of the tumble dryer. As the drum rotates, it slides over these plastic parts. Over time, the drum bearing bearings wear out and it can begin to cling to the housing and carry additional load on the engine. If this happens, the motor will shut off, preventing the dryer from rotating. To determine if the drum bearings are worn, inspect them for wear and if so replace them all as a set.

The drive motor (motor) turns the drum and impeller to release air. First, check the engine to determine if it hums. If the engine is still humming, remove the belt from the engine and check the fan impeller to make sure it is not clogged. Then, with the belt removed, try rotating the drum by hand. If the drum does not spin well, determine what is preventing it. If the drum rotates freely and the impeller is unobstructed, the drive motor may be defective. If you suspect the engine is defective, replace it. If you need help with high end dryer repair, call us right now!
