Dryer Repair — Common Problems & Solutions

Dryer Not Heating

A dryer that tumbles but does not produce heat is one of the most common issues. In electric dryers, failed heating elements, thermal fuses, thermostats or broken wiring can interrupt the heating circuit. In gas dryers, the igniter, gas valve coils or flame sensor may fail and prevent the burner from igniting. Vent restrictions can also trigger safety devices that cut power to the heater.

A technician will verify proper voltage supply, test the continuity of fuses, thermostats and heating elements, and on gas models observe ignition attempts. Once the faulty part is identified, it can be replaced and the venting system checked. Restoring correct heating shortens dry times and protects clothing from extended exposure to tumbling.

Dryer Takes Too Long to Dry

When a dryer technically heats but each load takes much longer than before, the most likely cause is restricted airflow. Lint build-up in the lint filter, internal ducts or the home’s vent line reduces the ability to move moist air out of the drum. Sensors that detect moisture may also fail, causing the dryer to misjudge when clothes are done.

A professional will inspect and clean internal ducts, check the outside vent hood and measure airflow. If moisture or temperature sensors are faulty, they can be tested and replaced. Fixing airflow issues not only improves performance but also reduces fire risk associated with lint accumulation.

Clothes Still Damp After Cycle

If a cycle ends and clothes are still damp or only partially dry, it can be related to overloading, sensor problems, poor airflow or weak heating. Modern dryers rely on moisture sensors and timed algorithms to decide when to stop the cycle. When those sensors are dirty or defective, the dryer might stop prematurely.

The technician will inspect sensor bars inside the drum, check settings, evaluate airflow and verify heater performance. Cleaning or replacing moisture sensors and correcting vent issues usually restores proper dry times, especially when paired with correct load sizes and cycle selection.

Drum Not Turning

A dryer that heats but does not spin, or makes a humming sound without turning the drum, often has a broken belt, worn idler pulley, seized drum rollers or a failing motor. Over time, support components wear out and create extra friction that the motor cannot overcome.

During diagnosis the technician will manually turn the drum, inspect the belt and pulleys and test the motor. Repairs may include replacing the belt, rollers, idler assembly or motor. Once these parts are restored, the dryer can tumble smoothly and quietly again.

Squeaking or Grinding Noise

High-pitched squeaks, chirps or grinding sounds while the dryer runs usually point to worn drum rollers, glides, bearings or idler pulleys. These parts support and guide the drum and move with every load. As they wear, they can create loud noises that get worse over time.

A technician will disassemble the front or rear of the dryer, inspect support components and replace any that show signs of wear. Replacing rollers and glides in sets often prevents repeat visits and keeps the dryer running quietly for years.

Burning Smell from Dryer

A burning or hot electrical smell from a dryer is a serious warning sign. It can indicate lint build-up close to the heater, overheated wiring or foreign objects such as plastic left in pockets. Continued operation in this condition increases the risk of fire.

The technician will unplug the dryer, inspect internal ducts, heater housing, wiring and the vent line. Lint and debris are removed, overheated components are replaced and the vent path is verified for proper airflow. Addressing the cause quickly helps keep the appliance and home safe.

Dryer Shutting Off or Not Completing Cycles

Some dryers start normally but shut off after a short time or never complete a full cycle. Overheating due to blocked vents, failing motors or faulty thermostats can trigger safety devices that interrupt power. Control board or timer issues can also lead to inconsistent run times.

A professional will check for restricted airflow, test thermostats and thermal fuses, and monitor current draw on the motor. If the control or timer is at fault, it can be replaced. Once the root cause is fixed, the dryer runs full cycles reliably without unexpected shutdowns.

Dryer Error Codes

Many newer dryers display fault codes when they detect problems with sensors, motors, heaters or communication between boards. These codes differ by brand and model and often require technical documentation to interpret correctly.

A technician will enter diagnostic mode, read stored codes and perform the recommended tests. Based on measurements and visual inspections, they can pinpoint whether the issue lies with a sensor, wiring or a control board. Correct diagnosis avoids guessing and unnecessary part replacement.
