LG dryer hums but will not start: a tiny spring mount in Palm City
On this LG Tromm dryer, the story gets more specific than a humming motor. Mark finds a broken attachment point for a small spring, then walks through the motor replacement and reassembly.

The dryer briefly runs during the inspection
Mark introduces an LG Tromm DLE8377NM that hums or buzzes when Start is pressed. Early in the recording he checks the machine with the cabinet opened, and the dryer briefly runs. He continues investigating rather than treating that moment as the end of the job.
That is a useful detail to include in a service request: does the appliance fail every time, or does it sometimes start? A short recording of the sound, made during normal use with the machine intact, can help describe the complaint.
The spring was small; its broken mounting point mattered
Around 2:35, Mark points out the spring arrangement on the motor. He compares the sides and explains that the attachment point for one spring has broken away. His finding is more specific than simply saying that the dryer needs a spring.
Because the place where the spring should attach is damaged, Mark proceeds with replacing the motor assembly. This is the finding on this machine, not a diagnosis for every dryer that hums.
The repair includes much more than swapping the motor
The footage follows the motor and blower work, then the drum and belt, front support and cabinet pieces. Mark reconnects the moisture-sensor wiring and works through the other connections as the dryer goes back together.
These details explain why the complete model matters and why access is part of the repair. The recording is a real service example, not a universal disassembly guide for all LG dryers.
Parts discussion and the end of the recording
Mark discusses the replacement motor he selected and compares part prices available to him at the time. Those spoken amounts belong to this older recording; they are not a current repair quote or a promise about the price of your parts.
