My dryer - not even 2 years old - is running louder than it normally does. Any suggestions would be great. I clean the filter with each load; not sure what else what I should do. I have treated it with kid gloves and I am the only one who uses it.
It sounds like your motor may be going out (search for motor replacement solution here).
Hopefully it is just a problem with grit in the system, or perhaps the felt gaskets have worked themselves loose. Either way, to clean out grit and inspect the system you'll need to access the interior and remove the drum. Here's how:
This will require you to disassemble the dryer. This is not hard - it will require the following tools:
crosstip medium screwdriver 1/4 inch socket 5/15 inch socket
TURN OFF GAS
Disassemble by taking apart the FRONT of the dryer:
a. Remove the door and opposite side door plugs (crosstip screws)
b. Remove the front panel - this exposes sheet metal bolts (5/16 inch) some with crosstip on left and right of unit. Set panel aside (right side) WITHOUT unplugging wires
c. Unscrew all the exposed bolts.
d. Top bolts left and right secure the unpainted metal hooks which secures the top of dryer. Unscrew these bolts and wiggle the metal retainer hooks off. Lift top and support to create 6 inch gap in the front (top unit hinges in back and has electrical connections - do NOT disconnect wires)
e. Release belt from pulley by reaching left and under drum (this is out of sight)
f. gently lift out drum and belt and set aside
This has exposed the interior.
Now: Maintenance time!
Using compressed air blow out all vents and the motor.
Wipe dust and grit out of crannies
Vaccuum bottom interior
Blow it out again
Using ultra fine steel wool (#0000) rub all contact areas of drum - belt region, and ends that contact the felt gaskets and the rollers at the rear
Check to ensure the felt gasket is in good shape all around the drum contact area. If it is torn, malformed or missing you'll need to replace. With any luck this is where your noise is coming from.
Check the blower cage. Ensure this is free of grit. It is worth taking off the eight screws to wipe out/blow out interior.
Worse case scenario - your motor is on the fritz (although this motor should give you 8-12 years of service). This will require removal, replacement. Motor cost is about $100. Labor will be more.

You may have a clogged air vent, check that the air vent hose is not smashed, if it is not smashed, have your dryer vent cleaned professionally, all the way from where the dryer connects to the wall to where the vent leaves the home,
Recheck the dryer operation, dryer vents should be cleaned every other year for optimum performance
You could set the dryer to manual dry and then no heat and see if the result is the same. If it runs then, you have a short in the heating system somewhere. If it still kicks out the breaker, you've got even worse troubles. Most likely an electronic board, and what ever caused it to go, like maybe still a heating system issue. I*d suggest calling a qualified service tech for this one. In the USA, you can find one at http://www.lge.com/us/support/repair/support-repair-provider-lookup.jsp
I am assuming that the hum indicates the motor is running but the drum is not turning. Possibly a broken drum belt however the check filter warning is indicating low air flow so the blower wheel could be broken at the connection to the motor shaft.
if you are sure vent is ok ..did you try a load with vent disconnected??...there is a chance there is something blocking air flow in lint screen/blower housing ..remove the 2 screws under filter remove all back screws remove 4 screws holding blower housing in place ..you then can pull complete housing out back
