Understanding the Problem
The dryer timer (mechanical or electronic timer/selector) controls cycle advance and timing functions. When a timer fails you may find the dryer won’t start, won’t advance through cycles, is stuck on one setting, or runs the wrong elements (for example runs heat when it should be cool). Timers fail for several reasons: internal motor burnout (on mechanical timers), worn or burned contacts from repeated arcing, broken selector shafts or knobs, or a failed electronic timer/control board. Before replacing the timer it’s important to confirm the timer itself is faulty and not another component (door switch, motor, thermal fuse, user interface board) causing the same symptoms.
Common Symptoms
Dryer won’t start or won’t advance through cycles, stuck on one cycle, timer knob won’t turn freely, cycles take too long or too short, or dryer runs continuously until manually turned off.
Common Causes
- Worn or burned internal contacts in the timer causing intermittent or no circuit switching
- Timer motor failure (mechanical timers) or electronic timer/control board failure
- Broken selector shaft, cracked timer housing, or damaged knob
- Faulty wiring or corrosion at the timer harness/connector

Helpful Repair Tip
Confirm a faulty timer by first checking for power into the timer with a multimeter and then checking continuity of the timer contacts or motor at different cycle positions. If power is present but the timer motor doesn’t run or contacts don’t change continuity as you advance the knob, the timer is the likely bad part.
Frequently Asked Questions
Can I replace the dryer timer myself?
Yes—if you’re comfortable with basic appliance repair and have a multimeter. Unplug the dryer, take a clear photo of the timer wiring or label wires before removal, remove the control panel/back access panel to access the timer, swap the old timer for the new one, reconnect wires exactly as they were, and test. If you’re not comfortable working with live voltage or complex wiring, hire a qualified technician.
How much does a timer replacement cost and how long does it take?
Parts typically range from about $40 for a simple knob/timer to $150–$250 for an OEM electronic timer assembly, depending on brand/model. Labor (if you hire a technician) is commonly $100–$200. A DIY replacement usually takes 30–90 minutes depending on access and model complexity.
