How to disassemble an LG dryer to remove a sock or something stuck in the blower

Samurai Appliance Repair Man

9,562 views

Dryer powers up, you select a cycle and push start and the dryer hums for a coupla seconds and then goes quiet for a while. This usually indicates something is blocking the drum from rotating. A sock stuck in the blower would do it.

A quick test to see if you have a drum blockage problem is to simply open the door and try to turn the drum by hand. If you can't turn the drum manually, ain't no way that dinky motor in there is gonna turn it, ether! Can I hear an, "A-freakin-men?"

If you need to get inside the dryer to remove a sock stuck in the blower or some other rolling problem, Sublime Master john63 steps us over the rice paper without a single tear or wrinkle:

Unplug dryer

Looking at the rear of dryer---the TOP COVER has what looks like "hinges"

At each plastic "hinge"---there are 2 phillips-type screws---remove only the lower screws at each "hinge".

Grasp the TOP COVER and slide rear about 2 inches---lift off & remove.

Standing at the front of the dryer---remove the WATER DISPENSER TRAY (release tab is at the bottom of the drawer).

Remove the 2 phillips screws that are now visible with the WATER DISPENSER DRAWER removed.

At the right-hand side of the CONTROL PANEL---remove a single phillips screw from the corner (opposite side of panel).

Disconnect plugs/wires that are directly behind the *jog dial* of the CONTROL PANEL

Remove the CONTROL PANEL---a small flat screwdriver helps to unsnap the **tabs** that secure the CONTROL PANEL

With the CONTROL PANEL removed---remove the 5 screws which secure the entire FRONT PANEL/COVER of the dryer. These screws are located at the top of the front panel---and were not visible with the CONTROL PANEL installed.

Pull the FRONT PANEL towards you just enough to allow unplugging the DOOR SWITCH

Lift the entire FRONT PANEL an inch or so & remove

Remove the LINT FILTER & place it inside the Drum

Looking at the front of the dryer---you'll notice a DUCT HOUSING (silver)

Remove the 2 phillips screws from the DUCT & slide it down-and-away.

With a bright flashlight---examine the BLOWER HOUSING---remove any clothing/obstruction

Re-assemble in reverse order

Common parts that cause rolling problems when they go bad:

Drum Roller

Belt, Drive

Drive Motor

Blower Wheel

Idler Pulley
