Dryer Not Working? Here Are the 5 Most Common Problems and Fixes

1. Dryer Won’t Start

• Faulty Power Supply – A tripped breaker, faulty outlet, or loose power cord can prevent the washer from turning on.
• Defective Lid Switch (Top-Load Models) – If the lid switch isn’t engaging properly, the washer won’t start.
• Broken Door Lock (Front-Load Models) – A malfunctioning door lock can prevent the cycle from starting.
• Malfunctioning Control Board or Timer – If the control board or timer fails, the washer won’t receive the necessary signals to start.

• Most dryers won’t start if the door switch is faulty. Test it by pressing the switch manually—if you don’t hear a clicking sound, it might need replacement.
• Use a multimeter to check for continuity. If there’s no continuity, replace the switch.

• The thermal fuse prevents overheating, but if it blows, the dryer won’t start.
• Locate the fuse (usually on the blower housing), test it with a multimeter, and replace it if necessary.

• If the start switch fails, the dryer won’t respond when you press the start button.
• Use a multimeter to test the start switch and timer; replace any defective components.

2. Dryer Won’t Heat Up

• If the heating element fails, the dryer will tumble but won’t produce heat.
• Use a multimeter to test for continuity. If there’s none, replace the heating element.

• A blown thermal fuse can stop the heating function.
• Check the fuse with a multimeter and replace it if necessary.

• If you have a gas dryer, a faulty igniter or gas valve solenoid may prevent heat production.
• Inspect the igniter for visible damage and test it with a multimeter.
• If the igniter glows but doesn’t ignite the gas, the solenoid coils may need replacement.

• A restricted airflow due to a clogged vent or dirty lint filter can cause heating problems.
• Clean the lint trap before each load and inspect the vent hose for obstructions.

3. Dryer Takes Too Long to Dry Clothes

• A clogged vent restricts airflow, causing inefficient drying.
• Disconnect the vent hose and clean it with a vacuum or brush. Ensure the outside vent is free of obstructions.

• Excess lint buildup reduces airflow and extends drying time.
• Clean the lint filter after each cycle to maintain efficiency.

• Stuffing too many clothes in the dryer prevents even airflow.
• Reduce the load size and dry clothes in smaller batches.

• A malfunctioning cycling thermostat may prevent the dryer from reaching the correct temperature.
• Test the thermostat and heating element with a multimeter and replace them if necessary.

4. Dryer is Making Loud Noises

• Rollers help support the drum, and when they wear out, they can cause a loud rumbling sound.
• Inspect and replace damaged rollers to resolve the noise.

• A frayed or broken drive belt can create a thumping sound as the drum rotates.
• Check the belt for signs of wear and replace it if necessary.

• If you hear a grinding or screeching noise, the motor bearings may be worn out.
• If the motor is failing, it may require professional repair or replacement.

• Objects like lint buildup or small clothing items can get caught in the blower wheel.
• Inspect the blower wheel for obstructions and remove any debris.

5. Dryer Shuts Off Too Soon

• A blocked vent can cause the dryer to overheat and shut off as a safety measure.
• Clean the vent and exhaust duct to improve airflow.

• Some dryers have moisture sensors that detect dryness levels. If the sensor malfunctions, it may shut the dryer off too early.
• Clean the sensor with a damp cloth to remove any buildup. If the issue persists, replace the sensor.

• If the high-limit thermostat fails, it may incorrectly sense overheating and shut the dryer off.
• Use a multimeter to test the thermostat and replace it if needed.

• If all other components check out, the issue may be with the main control board.
• Inspect the control board for visible damage and replace it if necessary.
