What to Do When a Dryer is Not Turning
Many people expect a dryer to work without a question and when a problem arises, they may feel clueless when troubleshooting it. A dryer drum not turning is among the most common problems and can be caused by a variety of broken components.
Check that the dryer is plugged in properly and has power. Check the socket with an appliance that is working, such as a fan. If there is no electricity coming from the socket, check your house's fuse box and flip it to on if it has been tripped to off.
Check the dryer door switch to make sure it it working properly. A malfunctioning door switch is a common cause of a dryer drum not rotating. To check the door switch, you will most likely have to remove two screws from under the lint trap and pull it up to remove a portion of the dryer. Remove the wires from the door switch with the dryer unplugged. Using an ohmmeter, check to make sure you have continuity between the two wires. If there isn't, you will need to replace the door switch.
Check the thermal fuse if the drum of your dryer is not turning. The thermal fuse will automatically shut off the dryer if the heat inside is too high, but when it malfunctions, it causes the dryer to stop working completely. Before checking the thermal fuse, check to ensure that the vent of the dryer is not clogged, which could cause the dryer to overheat and keep the drum from moving.To gain access to the thermal fuse on most dryer models, you will need to remove the back panel of your dryer. Look at your dryer's manual to find the location of the thermal fuse and replace it with a new one.
Motor and Belt
Check the belt of your dryer if the motor is running but the drum does not move. The belt controls the movement of the drum from the power of the motor. The belt will either be located under the drum of the dryer, or in the back depending on the model. Find the location of the belt and, if it is broken, replace it with a new belt.
If the dryer drum is rotating then stops after about 30 seconds the motor is probably faulty and needs to be replaced. Before replacing the motor, check the fan blade of the dryer to make sure it is not blocked. This can cause the motor to cut out.
