Understanding the Problem
What the timer switch does: The timer switch (mechanical timer assembly) tells the dryer when to apply power to the motor, heating circuit, and other functions during a selected cycle. If the timer is faulty the dryer may not start, won't advance through cycles, won't heat on timed cycles, or shows erratic behavior. Step-by-step diagnostic and repair instructions: 1) Safety first: Unplug the dryer from the wall outlet (or switch off the breaker). Confirm power is off before you touch any components. 2) Access the control/timer area: For WED1485EW1 the timer is behind the control console. Remove the timer knob (pull straight off). Remove the screws securing the console or control panel (usually two or more screws under the console front lip or behind the knob). Tilt or lift the console to access the timer assembly. 3) Visual inspection: Look for burned or melted plastic, loose or corroded spade connectors, or broken gear teeth on the timer shaft. If you see obvious damage, the timer likely needs replacement. 4) Identify wiring and take a photo: Before disconnecting anything, take a clear photo of the timer wiring so you can reconnect correctly. 5) Mechanical check: With the panel still open and power still OFF, manually rotate the timer shaft (if it turns) to see if the internal cam advances and if any contacts make or break internally. If the shaft is loose or spins without engaging, the timer is bad. 6) Electrical continuity test: Use a multimeter set to continuity or ohms. Test the timer motor terminals (if present) and the selected contact pairs according to the timer diagram printed on the timer housing or service sheet. In a simple test, you should see continuity in certain switch positions and open in others — if you see no continuity where there should be continuity, replace the timer. If you’re not comfortable with electrical testing, skip to replacement. 7) Confirm other components: Before buying a new timer, rule out a bad door switch, thermal fuse, start switch, or motor. The timer only routes power — if downstream parts (thermal fuse, heater, motor) are open, the dryer may appear to have a timer problem. Test thermal fuse for continuity, and make sure the motor will run when supplied power. 8) Remove the old timer: With power still OFF, disconnect the spade connectors (use your photo as a guide). Remove the mounting screws and pull the timer assembly out. 9) Install replacement timer: Position the new timer, secure mounting screws, reconnect each wire to its matching terminal (match picture or labeling), reinstall the control console and knob. 10) Test the dryer: Restore power and run a short test cycle. Observe that the timer advances and the dryer starts and heats as expected. If it still doesn’t work, recheck wiring and fuses. How to fix (practical): If the timer fails tests or visibly damaged, replace the complete timer assembly with the model-specific OEM or equivalent replacement. Ensure connectors are tight and no other protective devices (thermal fuse, thermostat) are open. Safety note: Always disconnect power before testing or replacing the timer. When testing with power applied (only if you know what you’re doing), use insulated tools and keep hands clear of moving parts. If unsure, contact a qualified appliance technician.
Common Symptoms
Dryer won't start or won't advance through cycle, timer won't click or turn, dryer runs continuously or stops mid-cycle, certain cycles don't heat.
Common Causes
- Worn or broken internal timer gears/cams
- Burned or corroded electrical contacts inside the timer
- Faulty timer motor or worn shaft that doesn't engage
- Related component failure (thermal fuse, start switch, motor) causing similar symptoms

Helpful Repair Tip
Confirm a bad timer by checking for continuity on the timer motor and switch contacts in multiple timer positions and by observing whether the shaft turns and advances the internal cams. If the shaft spins freely with no cam engagement, replace the timer.
Frequently Asked Questions
Can I run the dryer if the timer is bad?
Not safely. A bad timer may leave the dryer without proper sequencing or safety interlocks. It can cause the dryer to run continuously or not heat at the right times. Replace a faulty timer before continued use to avoid safety risks and further damage.
How long does it take to replace the timer on a WED1485EW1?
Typical replacement takes 30–60 minutes for a competent DIYer: unplug, remove knobs and console screws, swap the timer assembly (using a photo of wiring for reference), and reassemble. Allow more time if you need to diagnose other parts first.
