Upon inspection, the LG dryer was not heating, indicating a potential issue with its high limit switch. I began by ensuring the dryer was unplugged for safety. I accessed the dryer's back panel, carefully removing it to expose the internal components. The high limit switch, a crucial safety device, was identified and tested using a multimeter. It was found to be faulty, as it failed to register continuity. I then ordered a replacement high limit switch, ensuring it matched the model specifications. After receiving the part, I reinstalled the back panel, connected the new switch, and restored power. The dryer was tested, and it successfully heated, confirming the repair. The dryer now functions correctly, and the customer is satisfied with the restored performance.
