If your clothes dryer is stopping and then starting again without any apparent repairs being made to it, there could be a few potential causes:
Overheating: Many modern clothes dryers are equipped with thermal sensors that detect when the dryer is getting too hot. If it overheats, the sensor will automatically shut off the dryer as a safety precaution. Once the dryer cools down, it may start working again. Overheating can be caused by various factors such as a clogged vent, lint buildup, or a faulty thermostat.
Power fluctuations: Fluctuations in the electrical supply can sometimes cause the dryer to temporarily stop and start again. This can be due to issues with your home's electrical system or external factors affecting the power grid.
Load imbalance: If the clothes inside the dryer are not evenly distributed or the load is too heavy, it can cause the drum to become unbalanced. In such cases, the dryer's safety features may stop the cycle until the load is redistributed or adjusted.
Door switch issues: The door switch is a safety feature that prevents the dryer from running if the door is open. If the switch is faulty or not properly engaged, it can cause the dryer to stop and start intermittently.
Control board problems: A malfunctioning control board can lead to erratic behavior in the dryer. It may cause the dryer to stop unexpectedly or experience other irregularities in its operation.
Aging or worn components: As dryers age, some of their internal components may wear out, leading to irregular operation. This could include issues with the motor, belts, or other mechanical parts.
Environmental factors: Dust, debris, or pests getting inside the dryer and interfering with its components could also cause it to stop and start.
To troubleshoot the issue, it's best to start by checking simple things like ensuring the dryer is adequately ventilated and the load is balanced. You may also want to check the door switch and clean any lint or debris from the dryer's interior. If the problem persists, it's advisable to have a professional technician inspect and diagnose the dryer for more complex issues with its internal components.
