Finding quality replacement pieces can be tricky but Simpson dryer parts NZ is a sure bet to stock what you’re looking for. Let’s dive into the crucial elements that keep your dryer functioning efficiently and discover how a little know-how can prolong its lifespan.

The Drum

The drum is the heart of your dryer, playing a crucial role in the drying process. It’s the significant, cylindrical component where you place your wet clothes. During the drying cycle, the drum rotates, tumbling the clothes to ensure even exposure to heat and air. This tumbling action helps to separate the garments, allowing hot air to circulate and dry them more efficiently. Without a functioning drum, your dryer couldn’t dry clothes uniformly, leading to damp spots and longer drying times.

Common Issues:

  1. Unusual Noises: If your dryer makes strange noises, it could be due to a misaligned drum or worn-out drum rollers. A thumping or squealing sound is a standard indicator that something is amiss.
  2. Clothes Not Drying Evenly: This could be a sign of a damaged drum or worn-out rollers and axles, which prevent the drum from rotating smoothly.
  3. Drum Not Spinning: This issue might be caused by a broken belt or motor essential for the drum’s movement.

Maintenance Tips:

  1. Regular Inspections: Periodically check the inside of the drum for foreign objects, such as coins or buttons, that might get stuck and cause damage. Ensure the drum rotates smoothly and doesn’t wobble.
  2. Clean the Drum: Wipe down the interior of the drum with a damp cloth to remove any lint or residue that can accumulate over time. This helps maintain optimal airflow and prevent potential clogs.
  3. Check and Replace Rollers: If the drum isn’t rotating smoothly, inspect the rollers and axles for wear and tear. Replacing these parts can prevent further damage to the drum and ensure smooth operation.
  4. Lubricate Bearings: Lubricate the drum bearings occasionally to reduce friction and noise. Use a high-temperature lubricant designed for dryer components.

The Heating Element

The heating element is critical to your dryer, as it generates the heat necessary to dry your clothes. Without it, your dryer would simply tumble your clothes without any drying effect. The heating element converts electrical energy into heat, which is then distributed throughout the drum by the dryer’s blower. This heat evaporates the moisture in your clothes, speeding up the drying process and ensuring your laundry comes out dry and warm.

Signs of a Faulty Heating Element:

  1. No Heat Production: If your dryer is running but not producing any heat, it’s a clear sign that the heating element may be faulty.
  2. Inconsistent Drying: Clothes that take longer than usual to dry or come out damp could indicate that the heating element isn’t functioning properly.
  3. Burning Smell: A burnt odor from your dryer can signify that the heating element is overheating or damaged.

How to Replace a Faulty Heating Element:

  1. Safety First: Always unplug your dryer and turn off the gas (if applicable) before attempting any repairs.
  2. Access the Element: Depending on your dryer model, you can locate the heating element by removing the back panel or accessing it through the front.
  3. Disconnect the Wires: Carefully disconnect the wires attached to the heating element. Make sure to note their positions for reassembly.
  4. Remove and Replace: Unscrew the mounting screws or clips holding the heating element in place and remove the faulty element. Replace it with a new one, securing it with the screws or clips.
  5. Reconnect and Test: Reattach the wires to the new heating element, reassemble the dryer, and plug it back in. Run a test cycle to ensure the dryer is heating properly.

Regularly checking and maintaining the heating element can prevent these issues, ensuring your dryer operates efficiently and your clothes dry quickly. Proper care of this essential part improves drying performance and extends your appliance’s lifespan.

The Thermostat

The thermostat in your dryer plays a vital role in regulating the appliance’s internal temperature, ensuring that your clothes dry at an optimal and safe heat level. It monitors the temperature inside the drum and cycles the heating element on and off to maintain a consistent temperature range. Without a properly functioning thermostat, your dryer could overheat, risking damage to your clothes, or underheat, resulting in damp laundry.

Diagnosing and Fixing Thermostat Problems:

  1. Inconsistent Drying: If your clothes consistently come out too hot or still damp, the thermostat might fail to regulate the temperature properly.
  2. Overheating: A dryer that gets excessively hot clearly indicates a malfunctioning thermostat, as it cannot shut off the heating element when the desired temperature is reached.
  3. No Heat: If the dryer isn’t producing heat, the thermostat might be stuck in the “off” position.

Fixing Thermostat Issues:

  1. Safety Measures: Always unplug the dryer before starting any repair work.
  2. Locate the Thermostat: Depending on your dryer model, the thermostat is typically found near the heating element or blower housing. Refer to your dryer’s manual for precise location.
  3. Test the Thermostat: Use a multimeter to check the thermostat’s continuity. A functional thermostat should show a reading of zero or near-zero resistance. If it shows no continuity, it’s defective.
  4. Replace the Thermostat: If the thermostat is faulty, disconnect the wires and remove any mounting screws. Install the new thermostat by securing it with screws and reconnecting the cables.
  5. Reassemble and Test: Put the dryer back together and run a test cycle to ensure the new thermostat regulates the temperature correctly.

Regularly checking the thermostat and ensuring it functions correctly can prevent many drying issues, maintain energy efficiency, and extend the life of your dryer.

The Motor

The motor is a crucial component in your dryer, responsible for driving both the drum and the blower. This dual functionality ensures that your clothes tumble and receive consistent airflow for efficient drying. The motor’s operation is essential for the dryer to perform its basic functions; without it, the drum wouldn’t spin, and air wouldn’t circulate, leaving your clothes wet and unprocessed.

Maintaining and Troubleshooting Motor Issues:

  1. Regular Cleaning: Keep the motor area free of lint and debris, as accumulated dust can cause overheating and reduce the motor’s efficiency.
  2. Listen for Noises: A humming, buzzing, or grinding sound can indicate motor problems. If you hear these noises, it might be time to inspect the motor.
  3. Check for Overheating: If the dryer frequently shuts off mid-cycle or the motor feels excessively hot, it might be overheating due to lint buildup or a failing motor.
  4. Inspect Motor Bearings: Over time, motor bearings can wear out, causing increased friction and noise. Regular lubrication and timely replacement can prevent motor failure.
  5. Test with a Multimeter: If the motor isn’t running, use a multimeter to check for continuity. A lack of continuity might indicate a broken motor that needs replacing.
  6. Replacement: When replacing the motor, ensure the dryer is unplugged. Disconnect the wires and remove any mounting screws. Install the new motor by reversing the removal process and securing it properly.


Understanding the essential parts of your dryer and how to maintain them is key to ensuring your appliance runs efficiently and lasts longer. From the drum’s critical role in tumbling clothes to the heating element that generates necessary warmth, each component plays a vital part in the drying process. The thermostat regulates temperature, and the motor powers the drum and blower, all working together to deliver perfectly dried laundry. Regular maintenance, such as cleaning lint filters, inspecting and replacing worn parts, and keeping the motor free of debris, can prevent common issues and costly repairs. By taking these proactive steps, you can extend the life of your dryer, save on energy bills, and ensure your clothes come out dry and fresh every time.
