If your Amana dryer starts then stops, or runs briefly then stops, the most likely causes are a faulty user control and display board (especially if the start/cancel button is intermittent) and a defective timer. After those, check the moisture sensor, then the motor relay, and finally the control board or main control board, since those are less common. Before buying parts, verify the door switch and touchpad/start button work, watch for error codes, and test the timer or relay with a multimeter if you are comfortable doing so; only replace the moisture sensor after ruling out the more common control and switch failures. This symptom can show up as the dryer stopping after a few seconds or shutting down midcycle, so follow basic diagnostics first. RepairClinic carries the exact user control boards, timers, moisture sensors, motor relays and control boards you may need and provides step-by-step guides and videos to walk you through the repair.

01 - Amana Dryer Moisture Sensor
The moisture sensor monitors the clothing’s moisture level and sends a signal to the control board when the clothes are dry. If the moisture sensor is malfunctioning, it could inaccurately report that the clothing have sufficient dried, causing the drum to stop spinning. However, this is rarely the case. Before replacing the moisture sensor check all the more commonly defective parts. If you have determined that all of the other components are working properly, replace the moisture sensor.

If both the door switch and dryer touchpad are working appropriately, it's possible the motor relay is defective. However, this is not that common of a problem. Before replacing the motor relay, check all the more commonly defective parts. If you determine that all of the other components are working properly, you can test the motor relay by using a multimeter and consulting the wiring diagram to help determine if it is malfunctioning.
If both the door switch and dryer touchpad are working appropriately, it's possible the control board is defective. However, this is not that common of a problem. Before replacing the board, check all of the more commonly defective parts. If you have determined that all of the other components are working properly, replace the control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)
If both the door switch and dryer touchpad are working appropriately, it's possible the main control board is defective. However, this is not that common of a problem. Before replacing the board, check all of the more commonly defective parts. If you have determined that all of the other components are working properly, replace the main control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)
If the dryer's start/cancel button is only working intermittently, it's likely the user control and display board is malfunctioning and causing the dryer to stop running. A new board will need to be installed to resolve the problem.
If both the door switch and dryer touchpad are working appropriately, it's possible the timer is defective. However, this is not that common of a problem. Before replacing the timer, check all the more commonly defective parts. If you determine that all of the other components are working properly, test the timer by using a multimeter and consulting the wiring diagram. If the timer is defective, replace it.
