LG DLG2251W won't heat up

SOURCE: lg dryer not drying

Do not keep it higher temp unless bedsheets are inside.For normal clothes temp must be at normal level.If more steam remains inside then only clothes will remain damp.Look out for correct RPM.This problem comes due to drive belt also. Even it looks tight just replace blindly.Hope this will solve your problem.All the best to you.

SOURCE: LG DLG 5988 Gas Dryer Does not heat and does not dry

same exact problem for a year and a half now....soooooo frustrated with a 1000 dollar dryer.  NO LG 

SOURCE: front load gas dryer lg model dlg 5988w does not heat

This can obviously be several things, but I would first check the small safety thermostat. On the gas models, there is a small pin sticking out of it which can be pushed back in to reset it. It is located on the heater housing and is only about the size of a dime, with two wires on it. This will trip out easily if your vent was not clean, or is long or restricted in some ways (like using flex ducting)
If you need more help getting to it, let me know and I'll give you more instructions.

SOURCE: LG DLG2524W DRYER WORKS FINE EXCEPT DOESN'T HEAT UP

1. Open dryer door and remove the phillips head screws at the 5 and 7 O'Clock positions. 2. Remove three screws at very back, allowing top cover to be moved back about an inch and lifted off. 3. remove screw at top left and top right from front top panel. 4. pull plastic front panel along top edge to release front top panel. (watch for sharp edges) 5. Swing top up and over onto top of dryer. 6. Unplug light and door switch. 7. remove four screws at top of large lower panel. 8. lift panel up a bit and off. 9. unplug sensor plug at bottom allowing panel with door to be set aside. 10. gas dryer has dime sized high limit thermostat on left front side of burner chamber. Has two wires on it, with a small pin in the center. Push the pin in. Reassemble and clean out vent, eliminating flexible venting, replacing with rigid aluminum piping and elbows. Outside vent should have a four inch vent flap opening, not just a two inch if it is that style.

SOURCE: LG Dryer won't dry, no heat.

The heating coil is not too big of a problem to replace if you are mechanically inclined and have tools to do the job.
If you plan to try to repair the problem yourself, then the first thing you want to do is unplug the dryer from the electric.
Remove the back of the machine and try to locate the air tube going from the blower to the drum. Normally inside the air tube you will find the heating coil and the thermostats/thermistor.
Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST. This could cause a fire, as you have removed the saftey of overheat from the machine.
Good Luck,
Hope this helps
