Understanding the Problem

The timer (also called the timer control or selector) coordinates the dryer’s cycles — starting the motor, engaging heat, and advancing through timed steps. When a timer fails the dryer may not start, may stop mid-cycle, may not advance through cycles, or may run continuously without heating control. Because the timer is an electromechanical device with a small motor and internal contacts, wear or burned contacts are common causes of failure. Replacing the timer is usually straightforward for someone comfortable with basic appliance repair: disconnect power, access the control console, remove the old timer and swap in the replacement. However, it’s important to confirm the timer is actually the problem before ordering parts — symptoms overlap with thermostats, thermal fuses, door switches, motor issues and wiring faults. Use a visual inspection and simple electrical checks (continuity on the timer motor and contacts, proper voltage to the timer during operation) to verify the timer is at fault.

Common Symptoms

Dryer won’t start or won’t advance cycles, stops mid-cycle, runs but won’t heat or won’t complete timed cycles, or the timer knob feels loose or spins without engaging.

Common Causes

  • Worn or burned internal contacts in the timer from years of switching current
  • Failed timer motor that no longer advances the cam or selector
  • Broken or loose timer shaft/knob or damaged wiring/harness to the timer

Helpful Repair Tip

Before buying a replacement, manually advance the timer with the dryer powered (or use a multimeter to check the timer motor for continuity) — if the dryer runs only when the timer is advanced, the timer motor or internal contacts are likely bad.

Frequently Asked Questions

How do I confirm the timer is bad?

Start with a visual check: burned contacts, melted plastic, or a loose spinning knob are signs. Use a multimeter: with power disconnected, check the timer motor for continuity. With the dryer powered (and taking safety precautions), observe whether the timer advances when the dryer is running or if the motor gets voltage. If advancing the timer manually makes the drum run or heat correctly, the timer assembly is likely defective.

Can I replace the Amana dryer timer myself and what safety steps should I take?

Yes, many DIYers can replace the timer. Important safety steps: unplug the dryer or flip the breaker, take a photo of the wiring for reference, discharge any capacitors if present, and handle parts carefully. Typical steps: remove the control console or back panel, detach wiring from the old timer one connector at a time, remove mounting screws, install the new timer, reconnect wiring exactly, reassemble and test. If you’re not comfortable working with live voltage or tracing wiring, hire a technician.
