Jenn Air Dryer starts then stops

If your Jenn Air dryer starts then stops — it usually points to an electronic control problem rather than the drum or motor. The most likely culprits are the user control and display board or the timer, both of which can cause the dryer to run briefly and then cut out. Less common causes include a faulty motor relay or a failed control board or main control board, and the moisture sensor is rarely the reason the drum stops. Before replacing parts, confirm the door switch and start/cancel button work, inspect boards for burned components, and test the timer or relay with a multimeter if you can. If the start button is intermittent, the user control/display board often needs replacement; if the unit stops after a few seconds and power cycling does nothing, check the timer next. Enter your model number on RepairClinic.com to see the exact replacement part that fits your dryer, then order the correct user control, timer, relay, or control board to get it running reliably again.

01 - Jenn Air 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.

02 - Jenn Air Dryer Motor Relay

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.

03 - Jenn Air Dryer Control Board

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.)

04 - Jenn Air Dryer Main Control Board

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.)

05 - Jenn Air Dryer User Control and Display Board

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.

06 - Jenn Air Dryer Timer

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.
