  If your LG Air Conditioner isn't turning on, there are several things you can check: * Ensure the power cord is properly plugged into the outlet and that power isolators are switched on. * Check for a blown fuse or tripped circuit breaker and replace the fuse or reset the breaker if necessary. * If there was a power failure, wait 3 minutes after power is restored before turning the unit back on. * Verify that the batteries in the remote controller are correctly inserted or replace them. * Also, make sure the air conditioner wasn't turned off automatically by a timer and turn it on.
