45. Verify smooth, quiet operation during the test cycle. The drum should rotate smoothly with minimal noise.
46. Listen for any unusual noises during the test cycle. There should be no squealing, thumping, or grinding noises.
47. Verify the drum rotates continuously without stopping or slowing down.
48. If the dryer operates smoothly and quietly with proper drum rotation, the repair is complete.

Safety Notes: Always unplug the dryer and turn off the gas supply (for gas dryers) before working on drum components. Get assistance when lifting the drum—it's heavy. Verify all components are properly installed and the belt is correctly routed before testing. Ensure the belt ribs face the drum and the smooth side contacts the pulleys. Replace all components in the kit together for optimal performance. Test operation through a complete drying cycle to verify smooth, quiet operation. This repair typically takes 90-150 minutes depending on dryer model and experience level. If uncomfortable working with dryer drum assembly or unfamiliar with belt routing procedures, hire a professional appliance technician.

1. The Samsung Dryer Repair Kit includes all components that commonly wear out together—all components should be replaced together for balanced performance and to prevent repeated repairs. The support rollers, idler pulley, and drive belt work as an integrated system. If only the belt is replaced but the rollers and idler are worn, the new belt will slip on the worn pulleys and wear out quickly. If only the rollers are replaced but the belt is worn, the new rollers will be damaged by the worn belt. Replacing all components together ensures balanced performance, optimal belt tension, smooth drum rotation, and long service life. Many professional technicians recommend replacing all components as a kit rather than individual components to prevent repeated repairs and customer callbacks.
2. The drive belt must be routed correctly around the drum, motor pulley, and idler pulley—improper belt routing causes belt slippage, squealing, and premature wear. The belt wraps around the drum with the ribbed side (grooves) facing the drum, under the idler pulley with the ribbed side facing up, and around the motor pulley with the ribbed side facing the motor. The ribs must engage with the grooves on the drum and motor pulley for proper grip. If the belt is installed backwards or routed incorrectly, the smooth side contacts the grooves, causing slippage and squealing. Always verify the belt routing matches your detailed photos before testing. Proper belt routing is critical for reliable operation and long belt life.
3. The support rollers support the rear of the dryer drum and allow smooth rotation—worn roller bearings cause squealing noises and thumping during operation. The rollers are mounted on the rear bulkhead and support the full weight of the rotating drum. Over time, the roller bearings wear out, causing squealing noises when the drum rotates. As the bearings wear further, the rollers develop flat spots, causing thumping noises as the drum rotates. Eventually, the rollers seize completely, preventing drum rotation. When support rollers fail, they must be replaced immediately—continuing to operate with failed rollers can damage the drum and dryer cabinet. The 6931EL3001E kit includes (4) high-quality replacement rollers with precision ball bearings for quiet, smooth operation.
4. The idler pulley maintains proper belt tension and prevents belt slippage—a worn idler bearing or weak spring causes belt slippage and squealing. The idler pulley is a spring-loaded component that presses against the belt, maintaining tension. The tension spring pulls the idler toward the belt, creating pressure. If the idler bearing wears out, the pulley doesn't rotate smoothly, causing friction and belt slippage. If the tension spring weakens or breaks, the idler can't maintain proper tension, causing belt slippage. Either condition causes squealing noises and belt wear. The new idler pulley assembly includes a precision ball bearing and new tension spring for reliable, consistent belt tension.
5. The drive belt is the critical link between the motor and drum—a worn or broken belt prevents drum rotation and stops the dryer from operating. The belt transmits power from the motor to the drum, rotating it during the drying cycle. Over time, the belt wears from friction, heat, and age. The rubber compound hardens, the ribs wear down, and cracks develop. Eventually, the belt breaks or slips so much that the drum doesn't rotate. A broken belt is one of the most common dryer failures. The new 6602-001655 belt is 93.5 inches long with a 5-rib design and high-strength rubber compound for reliable, long-lasting operation.
6. Lint accumulation on the support rollers, motor pulley, and idler pulley reduces efficiency and accelerates wear—regular cleaning prevents premature component failure. Lint from the dryer can accumulate on the rollers and pulleys, creating friction and reducing efficiency. This causes the motor to work harder, accelerating wear on all components. To prevent premature failure, clean the lint from the rollers and pulleys periodically. When replacing the repair kit components, clean the motor pulley and drum support surfaces thoroughly to remove all lint buildup. This ensures optimal performance and long component life.
7. The drum must be properly supported on the rear support rollers—improper positioning causes the drum to wobble or contact the cabinet, damaging the drum and dryer. When reinstalling the drum after component replacement, ensure it's properly seated on both rear support rollers. The drum should be centered and level with no wobbling or excessive play. If the drum isn't properly positioned, it can contact the dryer cabinet, causing damage. Always verify the drum is properly supported before reinstalling the front panel and testing the dryer.
8. Belt tension must be correct—too much tension causes excessive wear on the belt and pulleys, while too little tension causes belt slippage and squealing. The idler pulley maintains proper belt tension through the tension spring. If the spring is too weak, the belt slips. If the spring is too strong, excessive tension wears the belt and pulleys. The new idler pulley assembly is pre-calibrated for correct tension. After installation, verify the belt has moderate tension with no excessive slack. The belt should have slight give when pressed by hand but should not slip on the pulleys.
9. The motor pulley must be clean and undamaged for proper belt grip—a worn or damaged motor pulley causes belt slippage and premature belt wear. The motor pulley has grooves that match the belt ribs for proper grip. If the pulley is worn, damaged, or covered with lint, the belt can't grip properly, causing slippage and squealing. When replacing the repair kit components, inspect the motor pulley carefully. If it's worn or damaged, it should be replaced. Clean the pulley thoroughly to remove all lint and debris.
10. After replacing the repair kit components, manually rotate the drum several times to verify smooth operation before testing the dryer. This manual rotation test verifies that all components are properly installed and the belt is correctly routed. The drum should rotate smoothly with no binding, squealing, or unusual noises. If the drum doesn't rotate smoothly or makes unusual noises, stop and investigate before testing the dryer. This simple test prevents damage to the new components and identifies installation problems before they cause further damage.
11. The support rollers have a typical lifespan of 5-8 years with average use, but can be shortened by overloading the dryer or operating with a broken belt. Factors that shorten roller life include: overloading the dryer causing excessive stress on the rollers (mechanical damage), operating with a broken belt causing the motor to work harder (motor overload), lint accumulation on the rollers increasing friction (efficiency loss), manufacturing defects, or low-quality replacement rollers (premature failure). To extend roller life and prevent premature failure, don't overload the dryer, clean the lint filter before every load, clean the rollers periodically to remove lint, use genuine OEM rollers, and replace all kit components together when any component fails. Regular maintenance and prompt replacement of worn components ensure reliable dryer operation and prevent repeated failures.
12. The drive belt has a typical lifespan of 5-8 years with average use, but can be shortened by excessive heat, chemical exposure, or improper belt routing. Factors that shorten belt life include: excessive heat from overheating dryer (thermal damage), chemical exposure from detergents or fabric softeners (chemical damage), improper belt routing causing slippage and friction (mechanical damage), worn pulleys causing belt slippage (indirect damage), manufacturing defects, or low-quality replacement belts (premature failure). To extend belt life and prevent premature failure, maintain proper belt tension, keep the motor pulley and drum clean, don't overload the dryer, use genuine OEM belts, and replace all kit components together when any component fails. Regular maintenance and prompt replacement of worn components ensure reliable dryer operation and long belt life.
