LG Dryer Error Code tE (wire connection)

The tE code on an LG dryer signals that the power supply wires at the terminal block are incorrectly connected or loose. This applies only to electric dryers and involves the black, white, and red wires that deliver 240-volt power to the unit. The dryer will not operate normally until the wiring is verified and corrected. Check the wiring diagram inside the dryer panel or on the installation guide for your specific cord configuration.

No, you should not attempt to run the dryer with the tE code active. An incorrect or loose wire connection at a 240-volt terminal block is a potential fire and electrical hazard. The dryer should remain unplugged until the wiring issue is identified and properly corrected.

If the fix is simply tightening a loose wire or repositioning a wire to the correct terminal, there may be no parts cost at all, though a service call from a technician could run anywhere from $75 to $150 depending on your area. If a new power cord is needed due to damage or a cord type mismatch, replacement cords typically range from $15 to $40. Labor costs for a professional repair will vary based on the complexity of the wiring issue found.

A knowledgeable homeowner comfortable working around appliance wiring can often resolve this by inspecting and correcting the terminal block connections. You must disconnect the dryer from power completely before touching any wiring at the terminal block. If you are unfamiliar with high-voltage wiring or unsure which terminals the wires belong on, hiring a qualified appliance technician or electrician is the safer choice.

A simple reset will not permanently clear the tE code if the underlying wiring problem is not corrected first. The code will return as soon as the dryer powers on and detects the same incorrect or loose connection. The wiring at the terminal block must be inspected and fixed before the code will stay clear.
