1. Unplug the dryer from the electrical outlet to ensure complete power disconnection.
2. Close the gas supply valve (if applicable for gas dryers) to prevent gas discharge during disassembly.
3. Empty the dryer of any clothes or items inside.
4. Remove the lint filter from the lint trap and set it aside.
5. Take multiple photos of the control panel, timer location, and all wire connections before disassembly. Document the timer position, wire colors, terminal positions, and any visible components from multiple angles. This is critical for proper reassembly.
6. Remove the control panel by locating and removing the fasteners (typically 2-4 screws along the top or sides of the panel). The control panel may hinge forward or lift off completely depending on the model.
7. Support the control panel as you remove it to prevent damage to wires or components.
8. Locate the timer on the back of the control panel. It's typically a round or rectangular component with multiple wire terminals and a rotating shaft that connects to the timer dial.
9. Take detailed photos of all wire connections to the timer terminals before disconnecting. Each wire is color-coded and connects to a specific terminal. Document the wire color and terminal position for each connection.
10. Label each wire with masking tape indicating its color and terminal position (e.g., "orange wire - terminal A," "red wire - terminal B"). This is critical for proper reassembly.
11. Disconnect all wire connectors from the timer terminals. Pull each connector straight off the terminal—do not twist or bend the terminals.
12. Count the total number of wires connected to the timer and verify your photos show all connections clearly.
13. Remove the timer knob from the front of the control panel by pulling it straight off the timer shaft. Some knobs may have a set screw that must be loosened first.
14. Remove the timer mounting hardware from the back of the control panel. The timer is typically secured with a mounting nut, clips, or screws.
15. For nut-mounted timers: Use a wrench or socket to remove the mounting nut from the timer shaft on the front of the control panel.
16. For clip-mounted timers: Carefully release the mounting clips by pressing or prying them with a flathead screwdriver.
17. For screw-mounted timers: Remove the mounting screws from the back of the control panel.
18. Carefully remove the old timer from the control panel. Pull it straight back through the mounting hole.
19. Place the old timer on a clean work surface with adequate space for inspection.
20. Inspect the old timer for visible damage such as burnt terminals, melted plastic, corroded contacts, or broken components. This confirms the diagnosis.
21. Inspect the timer mounting hole on the control panel for damage or corrosion. Clean if necessary.
22. Inspect all wire terminals for corrosion, melted insulation, or damage. Clean corroded terminals with a wire brush or replace damaged wires.
23. Unpack the new WW02F00724 dryer timer from its packaging. Handle carefully to avoid damaging the timer or terminals.
24. Compare the new timer to the old one to verify the shaft length, terminal configuration, mounting style, and overall appearance match. Ensure you have the correct replacement part.
25. Verify the terminal labels on the new timer match the old timer (typically labeled A, B, C, D, etc.). The terminal positions must match for proper operation.
26. Inspect the new timer for any damage or defects before installation.
27. Position the new timer in the control panel mounting hole, inserting the timer shaft through the front of the panel.
28. Verify the timer is properly oriented by comparing it to your photos. The terminal positions must match the old timer orientation.
29. Secure the timer with the mounting hardware (nut, clips, or screws). Tighten firmly but not over-tightening (which can crack the timer housing or strip threads).
30. Verify the timer is properly seated and does not wobble or shift when gently pushed.
31. Reconnect all wire connectors to the timer terminals, matching the labels and photos you created earlier. Each wire must connect to the exact same terminal position as the old timer.
32. Verify wire color and terminal position for each connection against your photos. This is critical—incorrect wire connections will cause dryer malfunction or damage.
33. Double-check all wire connections before proceeding. Verify each wire is fully seated on its terminal and matches your documentation.
34. Verify all wires are accounted for and no terminals are left empty (unless they were empty on the old timer).
35. Reinstall the timer knob on the timer shaft by pushing it straight onto the shaft. Secure with a set screw if applicable.
36. Verify the timer knob rotates smoothly and clicks into position at each cycle setting.
37. Reinstall the control panel by aligning it with the dryer and securing all fasteners.
38. Reinstall the lint filter into the lint trap.
39. Restore the gas supply (if applicable) by opening the gas supply valve.
40. Plug the dryer back in and restore power.
41. Run a test cycle on a short timed dry setting (10-15 minutes) without clothes to verify proper timer operation.
42. Verify the dryer starts when the timer is turned to a cycle setting and the start button is pressed (if applicable).
43. Verify the dryer motor runs and the drum rotates during the test cycle.
44. Verify the heating element turns on (for electric dryers) or the gas burner ignites (for gas dryers) during the test cycle. You should feel warm air coming from the dryer vent within 2-3 minutes.
45. Verify the timer advances through the cycle. The timer dial should slowly rotate as the cycle progresses.
46. Monitor the timer advancement speed. The timer should advance at a consistent rate—approximately 1 minute of timer movement per 1 minute of actual time for timed dry cycles.
47. Verify the dryer stops automatically when the timer reaches the "off" position.
48. Verify the buzzer sounds at the end of the cycle (if applicable).
49. If the dryer does not start, verify all wire connections are correct and secure. Check the door switch is functioning properly.
50. If the dryer runs but doesn't heat, verify the heating element or gas burner wire connections are correct.
51. If the timer doesn't advance, verify the timer motor wire connections are correct and the timer motor is receiving power.
52. If the timer advances too quickly or too slowly, the timer may be defective or the wrong timer for your model. Verify the model compatibility.
53. Test all cycle settings (timed dry, automatic dry, air fluff, etc.) to verify proper timer operation across all cycles.
54. Run a full drying cycle with a typical load of clothes to confirm the repair is complete and the dryer operates normally.
55. Monitor the dryer for 24-48 hours of normal use to ensure it operates properly without unusual noises, smells, or performance issues.

Safety Notes: Always unplug the dryer before working on it. Close the gas supply valve (if applicable) to prevent accidental gas discharge. The timer controls high-voltage electrical circuits—ensure all wire connections are correct and secure before operating the dryer. Incorrect wire connections can cause dryer malfunction, component damage, electrical fires, or electrical shock. This repair requires significant electrical knowledge and proper wire identification—if you're uncomfortable with the process, consult a professional technician. Take detailed photos and label all wires before disconnecting—this is critical for proper reassembly.

Always take detailed photos and label all wires before disconnecting the old timer. Timer wire connections are complex and model-specific. Each wire must connect to the exact same terminal position on the new timer. Incorrect wire connections will cause dryer malfunction or damage. Label each wire with its color and terminal position before disconnecting.

Verify the timer model number matches your dryer model. Timers are highly model-specific and different timers may have different terminal configurations even if they look similar. Always verify your dryer model number matches one of the compatible models before ordering. Using an incorrect timer can result in non-fit or improper operation.

Test the door switch and start switch before replacing the timer. A faulty door switch or start switch can prevent the dryer from starting even if the timer is good. Before replacing the timer, verify the door switch closes properly and the start switch clicks when pressed. If either switch is faulty, replace it first.

This is a complete replacement timer assembly. The WW02F00724 includes the timer motor, internal cams, switches, and all mechanical components pre-assembled and ready for installation. You cannot replace individual components—the entire timer must be replaced if any part fails.

Timer replacement requires electrical knowledge. This repair involves electrical wire connections and can cause dryer malfunction or damage if connections are incorrect. If you're uncomfortable working with electrical systems, consult a professional technician.

Monitor the first few drying cycles after installation. After installing the new timer, run several drying cycles and monitor for proper cycle advancement, correct cycle duration, proper heating, and proper performance. Address any issues immediately before they affect drying performance.

Timer failure can have multiple causes. If the new timer doesn't solve the problem, the issue may be with the door switch, start switch, heating element, control board, or another component. Further diagnosis may be required to identify the root cause.Verify the timer motor is receiving power. If the timer doesn't advance, the timer motor may not be receiving power. Test the timer motor wire connections with a multimeter to verify proper voltage. If voltage is present but the motor doesn't turn, the motor may be faulty and the timer may need replacement.

This repair restores full dryer cycle control. A properly functioning timer is essential for reliable dryer operation. Replacing a faulty timer restores automatic cycle control and prevents the need for manual dryer monitoring.

Check the thermal fuse for proper operation. The thermal fuse is a safety device that blows if the dryer overheats. If the thermal fuse is blown, the dryer won't start even with a new timer. Test the thermal fuse and replace if blown before operating the dryer.

Verify all wire connections are correct before operating the dryer. Incorrect wire connections can cause dryer malfunction, component damage, electrical fires, or electrical shock. Double-check all connections against your photos before operating the dryer.

The timer motor is powered by a small AC motor. The timer motor runs continuously during the drying cycle to advance the internal cams and switches. If the timer motor fails, the timer won't advance and the dryer won't cycle properly.

This repair prevents dryer shutdown and restores automation. A properly functioning timer ensures automatic cycle control and prevents the dryer from running continuously or shutting down mid-cycle.

Keep the control panel clean. Lint and moisture can accumulate on the control panel and cause timer corrosion or malfunction. Clean the control panel regularly and wipe up spills promptly to extend timer life.

Never operate the dryer with the control panel removed. The control panel houses the timer and other critical controls. Operating the dryer without the panel can cause electrical hazards or component damage.

Test the timer advancement speed after installation. The timer should advance at a consistent rate—approximately 1 minute of timer movement per 1 minute of actual time for timed dry cycles. If the timer advances too quickly or too slowly, the timer may be defective or the wrong timer for your model.

Verify the timer knob rotates smoothly. The timer knob should rotate smoothly and click into position at each cycle setting. If the knob is difficult to turn or stuck, the timer shaft may be bent or the timer may be defective.This repair is cost-effective compared to dryer replacement. The cost of timer replacement ($80-150) is far less than the cost of a new dryer ($600-1,500+). Replace the timer promptly when failure is detected to prevent the need for expensive dryer replacement.

Monitor for intermittent timer operation. If the timer works intermittently (sometimes advances, sometimes doesn't), the timer motor may be failing. Replace the timer promptly to prevent complete failure and dryer shutdown.
