Steps:

1. Remove the lint filter from the door opening and clear away any visible lint.
2. Rinse the filter under warm running water to strip off the invisible dryer-sheet film.
3. Verify water flows straight through the mesh; if it pools keep rinsing until clear.
4. Pull the dryer forward so the rear is fully accessible.
5. Loosen the single quarter-inch hex screw on the small lower rear cover.
6. Swing the cover open to expose the power cord terminal block.
7. Examine the terminal block and cord lugs for burns, melted plastic, or loose wires.
8. Replace the damaged cord or terminal block before continuing any other tests.
9. Set the multimeter to AC volts and keep the dryer plugged in for this measurement.
10. Touch one probe to the center post and the other to the left post; expect about 120 V.
11. Repeat between center and right posts for roughly 120 V.
12. Measure left to right posts; the reading must be 208–240 V for proper heating.
13. If voltage is out of range, reset the breaker or consult an electrician for outlet defects.
14. Unplug the dryer to eliminate shock risk before resistance tests.
15. Switch the multimeter to continuity or ohms mode.
16. Place the probes on both fuse terminals at the bottom of the terminal block; 0 Ω or a beep means pass.
17. An OL reading identifies a blown fuse that must be replaced.
18. Remove the two quarter-inch screws securing each plastic console side.
19. Extract the four quarter-inch screws holding the metal console back cover.
20. Lift the cover up, remove the green ground screw, and set the panel aside.
21. Slide the console rearward, then tilt it up and off the cabinet top.
22. Keep the meter on continuity and identify timer terminals A and B using the wiring diagram.
23. Insert the probes firmly into the correct timer terminals.
24. Rotate the timer knob through heat settings; 0 Ω or a beep indicates the contacts close properly.
25. Constant OL means the timer, its shaft, or the knob is defective.
26. Remove the two Phillips screws at the rear corners securing the cabinet top.
27. Open the dryer door and remove the two Phillips screws located just inside the door frame.
28. Insert a flat screwdriver under the front edge of the top panel and pop the retaining clips.
29. Lift the top panel and rest it gently against the wall.
30. Disconnect the drum-light harness at the upper left if your model is equipped.
31. Remove the quarter-inch hex screw on each cabinet side below the top panel.
32. Support the door assembly and lift it upward to free it from the three lower support fingers.
33. Slide the door to the side, depress the latch on the short door-switch harness, and unplug it.
34. Move the door panel out of your workspace.
35. Reach behind the blower housing and pull the idler arm to the right to relieve belt tension.
36. Rest the idler arm on the small motor-mount tab to keep tension off the belt.
37. Slip the belt off the motor pulley and idler wheel.
38. Grasp the belt and lift the drum; slide the drum straight out of the front opening.
39. Inspect the heater pan, coils, and surrounding wiring for burns or broken parts.
40. Vacuum lint from the cabinet bottom, blower inlet, and vent passages.
41. Use a slim dryer-cleaning hose to remove debris around the motor and tight cavities.
42. Locate the silver-colored purple wire on the lower right of the heater pan.
43. If the insulation or connector is darkened, brittle, or melted, plan to replace the wire and possibly the heater pan.
44. Set the meter to ohms and pull one heater lead off the left-side terminal with needle-nose pliers.
45. Keep fingers clear of the heater pan’s razor-sharp edges.
46. Measure across the two heater terminals; about 43 Ω signifies a healthy element.
47. OL or a major deviation indicates the element has failed and requires replacement.
48. Disconnect the purple-wire spade on the right side of the heater pan.
49. Measure between that spade and each left-side heater terminal; target reading is roughly 21 Ω.
50. OL or readings far from 21 Ω mean the heater or connector is defective.
51. Pull one blue wire off the drum outlet thermostat on the heater pan.
52. Continuity across the large terminals should read 0 Ω or beep; OL equals a failed thermostat.
53. Measure resistance between the two orange-wire terminals on the thermostat; around 9 kΩ at room temperature is expected.
54. Values more than ±15 % from 9 kΩ require thermostat replacement.
55. Test the safety fuse, control inlet thermostat, and high-limit thermostat one at a time using the same continuity method.
56. Each sensor must read 0 Ω or beep; OL flags a bad part needing replacement.
57. Avoid touching or bending the exposed heater coils while working inside the pan.
58. Pre-position the idler arm on the motor-mount tab to free both hands for drum installation.
59. Slide the drum into the cabinet and seat the rear bearing in its socket.
60. Place the belt in the rear groove of the drum, textured side against the drum.
61. Route the belt around the motor pulley and idler wheel, then release the idler arm to tension the belt.
62. Rotate the drum by hand to confirm smooth movement and correct belt tracking.
63. Rest the door panel on the three lower support fingers of the chassis.
64. Reconnect the door-switch harness and reposition the plastic cover.
65. Pivot the door toward the cabinet, ensuring the drum bearing seats inside the front ring.
66. Align the side tabs and support fingers to keep the front panel square with the cabinet.
67. Drive the two short quarter-inch screws into the upper left and right corners of the front frame.
68. Close the top panel and push it forward until the retaining clips lock.
69. Install the two Phillips screws through the door opening to anchor the front panel to the top.
70. Replace the two Phillips screws at the rear of the cabinet top.
71. Plug the dryer in and run a high-heat cycle to verify that the drum turns and heat builds steadily.
72. If the dryer now heats normally, unplug it and finish reassembly; if not, recheck your tests.
73. Drive the two long Phillips screws downward through the front bulkhead brace into the chassis.
74. Replace the two identical Phillips screws at the rear corners of the top panel.
75. Engage the six console fingers in their slots and pivot the console forward until it clicks.
76. Reinstall the green ground screw through the rear panel and console frame.
77. Seat the rear metal panel, slide the locator tab into the console, and secure it with four quarter-inch screws.
78. Install the final two quarter-inch screws down through the console into the top panel.
79. Reconnect power and confirm the dryer now runs quietly and produces consistent heat throughout a full cycle.
80. If performance is normal, push the dryer back into place and reconnect the vent.
