Diagnosing the Problem

If your dryer is turning, but your clothes remain wet, the culprit might be a lack of heat. Begin by checking the thermal fuse and the heating element. A malfunctioning thermal fuse could interrupt the heating process, while a faulty heating element may need replacement. For accurate diagnostics, use a multimeter to measure continuity.

Strange sounds emanating from your dryer can be alarming. Investigate by examining the drum rollers, idler pulley, and the blower wheel. Over time, these components can wear out or accumulate debris, causing unwanted noise during operation. Lubricate where necessary or replace parts that show signs of damage.

If your dryer refuses to start, check the door switch and the thermal fuse. A defective door switch might not engage the dryer when the door is closed, while a blown thermal fuse could prevent the appliance from powering on. Replacing these components is relatively straightforward and can breathe new life into your dryer.
