If your Hotpoint dryer starts then stops, running briefly then stopping or the dryer stopping after a few seconds, begin by checking the door switch and the touchpad or start button since intermittent signals will halt the cycle. The most likely causes listed here, in order, are a malfunctioning moisture sensor that inaccurately reports dry clothes and stops the drum, a defective motor relay that cuts power to the motor, and failing control boards including the control board and main control board that can interrupt cycles or show signs of burning. A faulty user control and display board is likely if the start or cancel button works only intermittently, and a bad timer can also stop the dryer midcycle. Before replacing parts, test relays and the timer with a multimeter and consult your wiring diagram, and visually inspect circuit boards for burned or shorted components. When you identify the failed component, enter your model number on RepairClinic.com to find the exact replacement part for your dryer.
01 - Hotpoint 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.)
05 - Hotpoint 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.
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.
