If your LG dryer is not heating properly or has stopped working altogether, a faulty thermostat could be the cause. The thermostat is essential for regulating the temperature inside the dryer, ensuring efficient drying. When it malfunctions, it can lead to overheating, underheating, or complete failure. Replacing a broken thermostat is a straightforward DIY repair. In this guide, we’ll walk you through the steps to easily replace and install a new thermostat in your LG dryer, helping restore its performance quickly and efficiently.
Steps to Replacing and Installing an LG Dryer Thermostat
Here are the steps to replace and install a new thermostat in your LG dryer.
Step 1: Unplug the Dryer
To reduce the chance of electrical shock, unplug the dryer from the outlet before beginning any repairs.
Step 2: Find the Faulty Thermostat
Most LG dryers are equipped with one or more thermostats, including a high-limit thermostat and a cycling thermostat. While the cycling thermostat controls the temperature during the drying cycle, the high-limit thermostat keeps the dryer from overheating by turning off the heating element if it becomes too hot.
Consult your dryer’s service or user manual to find the thermostat. In most cases, the thermostats are located close to the blower housing or heating element. The front or rear panel of the dryer must probably be removed to reach them.
Step 3: Remove the Dryer’s Panel
To remove the screws holding the dryer’s front or rear panel in place, use a Phillips screwdriver. If you’re working with a rear panel, you may need to remove the lint filter first. Carefully take off the panel once the screws are removed, exposing the internal components of the dryer.
Step 4: Disconnect the Thermostat Wiring
Note how the wires are attached to the thermostat before removing it. Taking a picture of the connections or writing down the wire layout is a useful idea. This ensures that when you install the new thermostat, you can reconnect it properly.
After recording the wiring, carefully unplug the cables from the thermostat terminals. To prevent damage, do not pull directly on the wires.
Step 5: Test the Old Thermostat (Optional)
You can test the continuity of the thermostat with a multimeter to see if it’s broken. Place the probes on the thermostat’s terminals after setting the multimeter to measure resistance. The thermostat is broken and needs to be replaced if there is no resistance or continuity.
If the LG Dryer Thermostat is indeed faulty, proceed to the next step. If the multimeter shows continuity, the issue may lie elsewhere in the dryer.
Step 6: Remove the Old Thermostat
After the wiring is disconnected, you can then unscrew or unclip the thermostat from its current position using a screwdriver or pliers. To remove the old thermostat, you should gently pry it out without causing any harm to the other parts.
Step 7: Install the New Thermostat
Position the new thermostat in the same position as the previous one. Verify that the mounting holes are correctly aligned and that it fits securely. If it is screwed in, then tighten the screws gently but do not over-tighten it because this may lead to damaging the thermostat or other parts that are around it.
Step 8: Reconnect the Wiring
Connect the wires to the new thermostat based on the reference photo or notes you took before to ensure you connect each wire to the right terminal. Tighten the connections down by applying pressure on them.
Step 9: Reassemble the Dryer
After the thermostat is installed and the wiring is connected, it is time to put the dryer back together. Put the panel back in place and tighten the screws you took out before. Now is the time to replace any other pieces you removed, including the vent or lint filter.
Step 10: Test the Dryer
Reassemble the dryer, then plug it in and perform a test cycle. Turn the dryer on to the heat setting and see if any heat is produced. If everything functions properly and your clothes dry efficiently, the replacement is complete. If you still experience heating issues, double-check the thermostat connections and ensure the new part is working correctly.
Replacing the LG dryer thermostat is one of the easiest repairs that can be done to fix a dryer that has a heating problem and make it work efficiently. With these tips, you will be able to prevent professional repair costs and keep your appliance in good working condition. Safety first, and get professional assistance if needed.
