LG Dryer Not Heating Up

8 Reasons Why LG Dryer Not Heating Up – Let’s Fix It

When you put a load of laundry into your LG dryer, you expect it to produce heat and dry your clothes efficiently. However, there might be times when your LG dryer needs to be heating up properly, leaving you with damp clothes and frustration. This guide will explore eight possible reasons for this issue and provide insights on how to fix them.

Clogged Vents and Lint Filter

A common reason for an LG dryer not heating is clogged vents and a dirty lint filter. The dryer vent and lint filter work together to maintain proper airflow, which is essential for drying. If the vents are clogged, or the lint filter is full, the moist air from your wet clothes cannot escape, and the dryer cannot generate heat efficiently.

To fix this issue, follow these steps:

  • Clean the lint filter with warm water and a soft brush, ensuring it’s free of lint and debris.
  • Remove any buildup from the exhaust vent using a hose attachment or a long brush, paying close attention to any bends in the vent.
  • Check the exterior vent cover to ensure it’s not blocked or damaged, and replace it if necessary.

Schedule regular vent cleaning and maintenance to prevent future issues and ensure proper airflow.

LG Dryer is Overloaded

Overloading your LG dryer can cause it to stop heating. A dryer drum filled with too many clothes might not be able to generate enough heat to dry them effectively, resulting in longer drying times and potential overheating issues.

To fix this problem, consider these tips:

  • Reduce the load size, ensuring enough space for the clothes to tumble freely.
  • Separate heavy items like towels and jeans from lighter fabrics to create more balanced loads.
  • Avoid overstuffing the dryer with large items such as comforters and blankets, which can block airflow and reduce heating efficiency.
  • Consider investing in a larger capacity dryer if you consistently have large laundry loads.

Blown Thermal Fuse

The thermal fuse is a safety device that prevents your LG dryer from overheating. If it has blown, the dryer will not produce heat. This can occur if the dryer has been subjected to high temperatures or if the airflow to the heater unit is restricted.

To check if the thermal fuse is the problem, follow these steps:

  • Disconnect the dryer from the power source and remove the power cord from the back panel.
  • Locate the thermal fuse, which is usually found on the blower housing or near the LG dryer heating element.
  • Use a multimeter to test the thermal fuse for continuity.

If it shows no continuity, replace the fuse to restore heat to your dryer and investigate the cause of the overheating to prevent future issues

LG Electric Dryer Not Heating: Burnt Heating Element

The heating element is responsible for generating heat in electric dryers. The heating element might be burnt or damaged if your LG electric dryer is not heating. This can happen due to wear and tear, power surges, or overheating.

To determine if the heating element is the issue or heating problem, follow these steps:

  • Disconnect the dryer from the power source and remove the back panel.
  • Locate the heating element, which is typically found inside a metal casing near the bottom of the dryer.
  • Use a multimeter to test the heating element for continuity.
  • If it doesn’t have continuity, replace the heating element assembly to fix the issue and restore heat to your dryer.

Faulty Cycling Thermostat

The cycling thermostat controls the hot air temperature inside the dryer. The dryer might not heat properly if faulty, leading to damp clothes and extended drying times.

To check if the cycling thermostat is the issue, perform these steps:

  • Disconnect the dryer from the power source and remove the back panel.
  • Locate the cycling thermostat, which is usually found on the blower housing or near the heating element.
  • Use a multimeter to test the cycling thermostat for continuity.
  • If it shows no continuity, replace the thermostat to ensure your dryer heats efficiently.
  • Regularly check and clean the lint filter and vents to prevent overheating and prolong the life of the thermostat.

LG Gas Dryer Not Heating: Faulty Igniter

In gas dryers, the igniter ignites the gas to produce heat. If the igniter is faulty, the gas valve will not open, and the dryer will not heat. Igniters can fail due to wear and tear or damage from power surges.

To test the igniter, follow these instructions:

  • Disconnect the gas dryer from the power source and gas supply, and remove the front control panel.
  • Locate the igniter, which is typically found near the burner assembly.
  • Disconnect the igniter from the wiring harness of the burner assembly and check for continuity using a multimeter.
  • If it shows no continuity, replace the igniter to resolve the issue and restore heat to your dryer.
  • Ensure that the gas line supply is functioning correctly and that there are no leaks or blockages.

Flame Sensor is Not Working

The flame sensor is a critical component in LG gas dryers, as it detects the presence of a flame and allows the gas valve LG dryers to remain open. If the flame sensor is not working correctly, the gas valve will close, and the dryer will not heat.

To test and fix the flame sensor, follow these steps:

  • Disconnect the gas dryer from the power source and gas supply, and remove the front panel.
  • Locate the flame sensor, which is typically found near the burner assembly.
  • Use a multimeter to test the flame sensor for continuity.
  • If it still shows no heat continuity, replace the flame sensor to fix the problem and restore heat to your dryer.
  • Regularly inspect the flame sensor and other components for signs of wear and damage to prevent future issues.

The gas Valve Solenoid is Not Working.

The gas valve solenoid is responsible for opening and closing the gas valve in your LG gas dryer. If it’s faulty, the dryer will not produce heat. Gas valve solenoids can fail due to wear and tear or electrical issues.

To test and replace the solenoid, follow these instructions:

  • Disconnect the dryer from the power source and gas supply, and remove the front panel.
  • Locate the gas valve solenoid, which is typically found near the burner assembly.
  • Test the gas valve coils for resistance using a multimeter.
  • If the readings are out of range, replace the gas valve solenoids to restore heat to your dryer.
  • Ensure that the gas supply is functioning correctly and that there are no leaks or blockages.

Conclusion

In conclusion, understanding why an LG dryer not heating up can help you diagnose and fix the issue efficiently. Regular maintenance and inspection of your dryer’s heat source can prolong its life and ensure optimal performance. If you cannot resolve the issue yourself, it’s always a good idea to consult a professional repair technician to address the problem safely and effectively.
