An automatic clothes dryer may stop working mid-cycle without displaying any error codes due to various potential reasons. Some common explanations for this intermittent issue include:
Overheating: If the dryer's thermal fuse or thermostat malfunctions, the dryer may overheat and shut off as a safety measure. Once the dryer cools down, it may work normally again until it overheats once more.
Motor issues: The dryer's motor may be experiencing intermittent faults, such as overheating or internal electrical problems. When it overheats or encounters an issue, it will shut off, and after some time, it may work again until the problem reoccurs.
Ventilation problems: Poor ventilation can cause the dryer to overheat, triggering its safety mechanisms to shut down the unit. Proper ventilation is essential to keep the dryer running smoothly.
Drum obstruction: If there's an obstruction or resistance in the dryer drum's rotation, it can cause the motor to overwork and shut down. Once the obstruction is cleared or adjusted, the dryer may work again.
Power supply issues: Sometimes, electrical problems or fluctuations in the power supply can cause the dryer to stop working temporarily. When the power stabilizes, the dryer might work again until the next power issue.
Control board glitches: The electronic control board in the dryer might encounter intermittent malfunctions, causing it to shut down unexpectedly. Resetting the control board can sometimes temporarily resolve the issue.
Sensor malfunctions: Some dryers have sensors that detect moisture levels to adjust drying times. If these sensors are faulty or covered in lint, it could lead to mid-cycle shutdowns.
Door switch problems: The dryer's door switch might have intermittent issues, causing the dryer to stop when it falsely senses the door being opened.
Since the issue is intermittent, it can be challenging to diagnose without further troubleshooting. If the problem persists or worsens, it's best to contact a professional appliance repair technician to inspect and diagnose the specific cause of the mid-cycle shutdowns. They can accurately identify the problem and perform any necessary repairs to get your dryer working reliably again.
