Steps:

  1. Remove and inspect the filter inside the dryer for any clogs or debris.
  2. Rinse the filter under warm water to clear invisible residue left by dryer sheets.
  3. Dry and reinstall the filter, then confirm that airflow is unrestricted in the filter housing.
  4. Move the dryer to access the rear panel where the power cord enters.
  5. Remove the lower panel screw with a quarter inch hex head driver and open the panel.
  6. Look for any signs of damage or burnt wiring on the terminal block or cord.
  7. Use a multimeter set to AC voltage to confirm 120 volts on each leg to neutral and about 208 to 240 volts across both hot legs.
  8. Reset the breaker by turning it off, then cycling on, if voltage is incorrect, or replace the cord or consult an electrician if the outlet is faulty.
  9. Set the multimeter to continuity or ohms resistance. Ensure the dryer is UNPLUGGED for this and future tests that involve continuity or ohms.
  10. Place one meter lead on each side of the fuse near the bottom of the rear housing.
  11. Replace the fuse if the meter stays open line and does not show 0.00 ohms.
  12. Remove the two screws on each side of the plastic console with a quarter inch hex or Phillips bit.
  13. Remove the four screws holding the metal panel behind the console and lift the panel off.
  14. Refer to the schematic stored here for terminal labels and timer contact points.
  15. Use the multimeter on continuity or ohms to test the correct timer contacts while rotating the knob to a heat setting.
  16. If no continuity is found on the proper contacts at any setting, replace the timer.
  17. Inspect the dial and shaft for damage if the knob fails to rotate the timer internally.
  18. Remove two rear chassis screws on each side, then remove the two front screws inside the door opening.
  19. Use a pry tool or screwdriver to lift the top panel of the dryer slightly. The top could be gently tilted rearward to rest on the wall for easier belt - top access.
  20. Remove two hex head screws on each inside corner, then release the door harness connector carefully.
  21. Lift the whole front door assembly off the lower hinge fingers, but note the short door lock harness.
  22. Move the door aside or support it while disconnecting the door switch harness from the plastic cover.
  23. Reach behind the blower housing on the right side to release tension on the idler pulley.
  24. Detach the belt from the motor pulley and guide the belt free so the drum can lift out.
  25. Pull the drum forward, following the shape of the dryer cabinet to avoid snagging.
  26. Vacuum any lint or debris inside the cabinet and motor area to improve airflow.
  27. Check the purple wire on the lower right corner of the heater pan for burning or charring.
  28. Replace the wire if it appears damaged using a suitable wire kit specified by the device.
  29. Examine the spade terminal on the heater pan for burn marks that may require replacing the entire heater assembly.
  30. Disconnect one wire from the element carefully to avoid sharp edges.
  31. Use the multimeter on ohms or continuity and expect about 43 ohms for a healthy heating element.
  32. Move one lead to the purple wire side and measure about 21 ohms to each half of the element coils.
  33. Replace the heating element if readings show open line or are significantly off from expected values.
  34. Set the multimeter to ohms or continuity when testing each thermostat or safety fuse.
  35. Remove at least one wire from each thermostat or fuse to prevent false readings.
  36. Verify each large terminal shows near 0.00 ohms or a beep of continuity if in working condition.
  37. Check small terminals for around 9000 ohms on sensor style thermostats, replacing them if values are off.
  38. Replace any component that reads open line (OL) or has abnormal readings.
  39. Hook the idler pulley on the motor mount before sliding the drum into the cabinet using the belt.
  40. Align the rear drum bearing into its socket and confirm no obstructions by rotating the drum.
  41. Attach the belt onto the motor pulley and release the idler pulley to restore tension.
  42. Hang the front door panel on the lower chassis fingers and reconnect any door harness wiring.
  43. Tighten all front and rear chassis screws to secure the door and top panel in place.
  44. Reconnect the console by aligning its tabs and reinstall any screws that hold it together.
  45. Plug in the dryer and run it briefly to verify proper drum rotation and heating performance.
