If you smell gas around your LG dryer you should immediately turn off the gas supply at the valve behind the dryer and call your local gas company to come out and inspect the problem. If you are attempting to use liquid propane instead of natural gas please make sure this has been properly converted by a licensed installer or plumber.
If it turns out that the problem is not in the gas line, the dryer will require service. For further assistance, please request a repair.
