If you reach into your LG dryer model DLG2602R and discover your clothes are still soaking wet after the dry cycle has finished, your appliance is likely suffering from a lack of heat. Unfortunately, this is a common issue that is caused by a multitude of possible malfunctions. Once you’ve ruled out a problem with the high limit thermostat, the flame sensor, the thermistor, and the ignitor, you should consider examining the gas burner valve assembly. The gas burner valve assembly supplies gas to the dryer burner. A malfunctioning valve assembly won’t administer gas, which means your dryer won’t heat up. If you determine a faulty gas burner valve is causing your dryer’s no heat issue, keep reading to learn how to replace the valve assembly.

Before you start repairing your dryer, unplug it from the wall and turn off the gas supply valve. You should never attempt a repair without wearing the proper safety gear, such as, work gloves and goggles. If you’re not confident in your ability to successfully replace the gas burner valve assembly, or you do not feel comfortable working with the dryer’s gas system, please contact a dryer repair specialist to complete the replacement process.

How to Replace the Gas Burner Valve Assembly in Your LG Dryer

  1. Pull your dryer forward and away from your laundry room wall. On the back of your appliance, unthread the screws that secure the top panel to the dryer. Once the screws are out, pull the panel towards you, and then lift it up and off your dryer.
  2. At this point, you’ll need to disassemble the control panel. Before you disconnect any wires, we suggest taking a picture of all the wire connections, to ensure you can easily reconnect them during reassembly. After you’ve snapped a photo of the control board, start detaching the wire harnesses from the back of the board. Once all the wires are disconnected, take out the screws that hold the control board console to the dryer, and then pull the console off the front of your appliance.
  3. With the control board removed, you can disconnect the door switch, which you’ll find near the top, center of the door frame. Next, open your dryer door and unthread the screws that hold the front panel to the lint screen housing. Once the screws are out, close the door and unthread the screws at the top of the front panel. Then, carefully tilt the front panel backwards and pull it up and off your dryer.
  4. Now it’s time to take the control panel bracket off the dryer. First, locate the dryer light bulb and disconnect the wire harness running to it. Next, on the back of the bracket, you’ll find two wire retaining clips. Take out the wires being held in the retaining clips. Then, remove the screws holding the control panel bracket to the front of the dryer, and pull the bracket off your appliance.
  5. Near the bottom of your dryer, disconnect the wire harness that belongs to the moisture sensor. Once you’ve separated the wires, unthread the screws that secure the bulkhead to the dryer. Then, carefully lift the bulkhead off your appliance.
  6. Reach in-between the dryer floor and dryer drum to take the drive belt off the idler pulley and the drive motor pulley.
  7. Grab the drive belt on top of the dryer drum, and use it to help you guide the drum out of the dryer cabinet.
  8. With the drum removed, you can locate the gas burner valve assembly. Once you’ve spotted the component in the cabinet’s lower right hand corner, disconnect the wire harnesses running to the valve assembly terminals. Then, using a Phillips screwdriver, unthread the screws which secure the gas line to the burner valve. Once the screws are loose, carefully pull the gas line off the burner valve. Next, take out the screws holding the valve assembly to the mounting bracket, and then take the gas burner valve off the mounting bracket and out of the dryer cabinet.
  9. Before you can install the new valve, you’ll need to take the orifice off the old gas burner valve and place it on the new component. Once the orifice is securely attached to the new gas burner valve assembly, you can proceed with the installation process.
  10. Place the gas burner valve assembly on the mounting bracket. Make sure you line up the screw holes on the bracket with the screw holes on the valve assembly. Then, replace the screws used to secure the gas burner valve to the mounting bracket. Next, align the gas supply tube with the burner valve, and insert the tube into the valve. Once the tube and valve are connected, rethread the screws you took out earlier to secure the tube to the valve. To finish the installation, reconnect the gas burner wire harnesses to the valve terminals.
  11. Before you start putting your dryer make together, take a moment to check for any gas leaks. To do so, fill a spray bottle with soapy water, and turn the gas supply valve back on. Then, spray the gas burner valve with the soapy water. If you see any bubbles forming, a gas leak is present, meaning the connection is not tight enough. At this point, turn off the dryer’s gas supply, and try tightening the tube and valve coupling. Once you’ve adjusted the union, turn the gas back on, and run the gas leak test again. If no bubbles appear, the gas leak is no longer an issue, however, if bubbles are still forming, we suggest contacting a dryer repair technician to further inspect the problem.
  12. After you test for leaks and find none, turn the gas running to your dryer off, and start putting your appliance back together. Pick-up your dryer drum and carefully guide it into the dryer cabinet, ensuring the back of the drum sits on the drum rollers. Then, reach in-between the drum and the dryer floor to rethread the drive belt on the idler pulley and the drive motor pulley. Make sure the belt is installed in a zigzag formation.
  13. Retrieve the dryer bulkhead, and align it with the front of your dryer. Then, secure the part with the screws you took out earlier. With the bulkhead in place, reconnect the moisture sensor wire harness, and the light bulb wire harness.
  14. Now you can reattach the control board bracket. Once the bracket is in place, pull the door switch wire harness to the front of the dryer through one of the openings on the bracket, and then snap the wire into the retaining clips on the back of the bracket.
  15. Grab the dryer front panel and line it up with the front of your appliance. Before laying the panel flush, reconnect the door switch harness to the door switch, and then finish installing the front panel. Once you’ve added the screws to secure the panel, open up the dryer door, and rethread the screws that connect the front panel to the lint screen housing.
  16. Snap the control panel back on the dryer, and reattach the screws you removed earlier. Finish installing the control panel by reconnecting the wire harnesses that run to the back of the panel.
  17. To complete your repair, reinstall the dryer’s top panel, and then plug-in your appliance and turn the gas supply valve back on.
