The belt drives the drum through a pulley system attached to the motor shaft. The belt is held securely in place over an idler pulley and under a motor pulley by a spring-loaded arm or torsion bar that is part of the idler assembly. The idler assembly is attached to the rear motor support at the bottom left rear of the dryer. The configuration and parts of the idler assembly vary in different model dryers, as shown below. Note: The only times you need to check the belt and idler is if the motor runs but the drum does not rotate, or if the dryer is noisy and the noise has been traced to the idler. Causes for the drum not to rotate include broken belt, belt off the idler, loose motor pulley, or broken idler spring. Noise can be caused by the belt off of the idler, a broken belt, or worn idler bearings. CAUTION: Be careful when bending back idler arm or torsion bar; each is under high tension and could snap back on your hand. |  |

|
| Step 1: Be sure all dryer controls are turned OFF. Disconnect power supply at distribution panel and unplug dryer from receptacle.Watch for sharp edges on access panels and parts. |  |
| Step 2: Remove large, lower rear access panel by unscrewing 5/16'mounting screws with nut driver |  |
| Step 3: Determine which type of idler system is present in your dryer using the photos above. Steps 4-15 refer to the Type A system; Steps 16-22 to Type B; and Steps 23-29 to Type C. |  |
| Step 4: Inspecting Type A. Examine each component of the idler assembly for visible damage. Check belt to see if it is worn, broken, or off of idler. If belt is oft of idler, check spring for any breaks. |  |
| Step 5: If spring is broken, leave belt off of idler pulley and unhook spring. Hook one end of new spring onto idler arm and other end into hole on arm of motor bracket assembly. |  |
| Step 6: If belt is securely in place and drum does not rotate, check to see if pulley on motor shaft will turn freely. If the motor shaft does not turn, check both motor and blower. |  |
| Step 7: If belt needs replacing, make sure it is first off of idler pulley. Swing idler arm away from pulleys, and belt should pop off. CAUTION: Be careful that arm does not snap back on your hand. |  |
| Step 8: To replace belt, dryer top must be raised and dryer front removed. Open the dryer door and remove the screws along the top edge. then you can raise the top. Next loosen the two 5/16 screws at the bottom of the front panel. Next remove the two 5/16 screws on the inside of the cabinet towards the top that hold the front panel to the sides. Lean the dryer forward and lift it off. |  |
| Step 9: Slide loose belt to front of dryer and oft drum by tilting drum upward. Slip on new belt the same way and position it over marks on drum left by old belt. |  |
| Step 10: With belt loose from idler, check idler pulley and bearings for damage. Remove idler pulley from shaft by removing the E-clip retaining ring. |  |
| Step 1 1: There are two bearings on either side of the pulley that have a slice through the side and a key that aligns with a slot inside the pulley. Bearings should be present and fit tightly. To remove or replace bearing, rotate until it goes into or out of position. |  |
| Step 12: Lubricate pulley shaft lightly with automotive type grease before reattaching idler pulley. Slide pulley back on shaft and reattach washers and retaining ring. Adjust retaining clip so pulley spins freely. |  |
| Step 13: If the idler pulley is cracked or broken, replace both pulley and bearing. Once pulley is reattached to shaft, rethread and align belt. |  |
| Step 14: To reattach belt to idler, rethread belt over top of idler pulley and underneath motor pulley. Release idler arm slowly. Check alignment on idler pulley by turning drum in both directions. |  |
| Step 15: If belt is positioned near front or rear edge of idler pulley, bend idler arm to center belt on idler pulley. |  |
Step 16: Inspecting Type B.
Examine each component in the idler assembly for visible damage. Check belt to see if it is worn, broken, or off of idler. If belt is off of idler, check spring for any breaks. |  |
| Step 17: If spring is broken, leave belt off of idler pulley and remove spring from tab on dryer base and bottom of idler arm. Hook new spring back into tab and idler arm. |  |
| Step 18: If belt is securely in place and drum does not rotate, check to see if pulley on motor shaft will turn freely. If the motor shaft does not turn, check both motor and blower | |
Step 19: If belt needs replacing, make sure it is first off of idler pulley. Swing idler arm away from Pulleys, and belt should pop off.
CAUTION: Be careful arm does not snap back on your hand. Reinstall belt as described in Steps 8 and 9. |  |
Step 20: With belt loose from idler, check idler pulley and bearings as described in Steps
10-13. |  |
Step 21: To reattach belt to
idler, rethread belt over idler pulley and underneath motor pulley. Release idler arm slowly. Check alignment on idler pulley by turning drum in both directions. | |
| Step 22: If belt is positioned near front or rear edge of idler pulley, bend idler arm as shown to center belt on idler pulley. |  |
| Step 23: Inspecting Type C. Examine each component in the idler assembly for visible damage. Check belt to see if it is worn, broken, or oft of idler. |  |
| Step 24: If belt is securely in place and drum does not rotate, check to see if pulley on motor shaft will turn freely. If the motor shaft does not turn, check both the motor and blower | |
| Step 25: If belt needs replacing make sure it is off of idler pulley.Swing torsion bar down, and belt should pop off. CAUTION: Be careful arm does not snap back on your hand. Reinstall belt as described in Steps 8 and 9. |  |
| Step 26: With belt loose from idler ,check idler pulley and bearings for damage. To access pulley, remove torsion bar mounting screws from dryer base. Lift off torsion bar and pulley. |  |
| Step 27: Remove pulley retaining clip with screwdriver or needle-nose pliers, being careful not to damage clip. Check bearings as described in Step 11. |  |
Step 28: Lubricate torsion bar
shaft with automotive type grease at end that attaches to pulley. Reattach idler pulley. Slide pulley onto shaft and reattach retaining clip, adjusting so that pulley spins freely.
|  |
| Step 29: To reattach belt to idler, pull torsion bar down. Rethread belt underneath motor pulley and over top of idler pulley. Release torsion bar slowly. |  |
| Step 30: Reassemble dryer and reconnect power supply. | |
