Diagnosis
A high-resistance connection at the cord entry point. This is caused by a loose internal terminal or a broken wire strand, creating heat through resistance.
How to Fix It
Unplug the dryer immediately and do not use it. Disassemble the handle. Inspect where the cord wires solder to the main PCB. Look for darkened, cracked solder joints or melted insulation. Cut the damaged cord section back, strip fresh wire, and resolder securely to the board.
If That Didn't Work
The fault may be further up the cord. The entire power cord must be replaced. Use a heavy-duty, high-temperature replacement cord of the same gauge and length. Do not attempt a repair splice.
Heads Up
This is a serious fire hazard. The heat can melt internal components and ignite lint. Stop using the dryer until this is professionally repaired or replaced.
