Understanding the Problem
The timer on an Amana dryer controls cycle advancement and supplies power to the motor, heater and other components at the correct times. When the timer fails, the dryer may not start, may not advance through cycles, may run continuously, or may stop heating even though the motor runs. Timers can fail mechanically (worn gears/cams) or electrically (burnt or open contacts), and sometimes an intermittent failure will make diagnosis confusing. Replacing the timer is a straightforward repair on most Amana models but requires confirming the timer is actually the faulty component. Commonly a faulty timer is the direct cause when the dryer gets power but nothing advances, the timer knob does not turn during a cycle, or the timer doesn't click/step when a cycle is started. Always verify by checking continuity on the timer terminals and isolating other components (door switch, thermal fuse, drive motor) that can produce similar symptoms before replacing the timer assembly.
Common Symptoms
Dryer won't advance through cycles, timer knob doesn't move during operation, dryer runs but won't heat or stop, intermittent or no clicking when cycle is started.
Common Causes
- Worn mechanical gears or cams inside the timer assembly
- Burnt or open electrical contacts in the timer due to arcing or overload
- Mechanical binding or broken drive components (knob shaft, coupling) preventing timer advance

Helpful Repair Tip
Before ordering a timer, run the dryer on a timed cycle and watch whether the timer dial advances; also test timer continuity across its switch terminals with a multimeter. If the dial doesn't move but the motor runs, the timer is very likely bad.
Frequently Asked Questions
How can I be sure the timer is the problem and not the motor or a thermal fuse?
Start by observing cycle behavior: if the motor runs but the timer dial does not advance, the timer is likely bad. Use a multimeter to check continuity across the timer switch terminals for the selected cycle positions. Also check the thermal fuse (continuity) and the motor (runs when energized). If the dryer has power and motor runs but the timer contacts are open or the dial won't advance, replace the timer. If you're unsure, take clear photos of the timer wiring and compare voltages against the wiring diagram or consult a technician.
Can I replace the Amana dryer timer myself and how long will it take?
Yes—if you have basic tools and comfort working with electrical appliances. Typical steps: unplug dryer, remove the control panel or console (remove knobs and screws), label and photograph wiring connections, disconnect wires, remove old timer, install new timer, reconnect wires, reassemble and test. Most DIYers complete this in 30–90 minutes. Always disconnect power first, match the new timer to the exact model number, and consult the dryer wiring diagram. If you’re not comfortable working with mains electricity, hire a qualified appliance technician.
