The drying time seems to take much longer than usual on my LG machine, could this be down to overloading?
A common cause of longer drying times can be an overloaded dryer. If the load size is too large, it will prevent a proper air circulation, which in turn will hinder proper drying.
It can also prevent proper tumbling, which can cause some items to be dry and some to be wet.
How to Fix
Correcting overloading is, thankfully, very simple - you simple remove or rearrange some of the items in the dryer.
