LG tumble dryer squeaking and not sensor drying properly

i have an LG TDC70045E 7kg condenser dryer

for a few months now it’s been squeaking when drying and it’s also not drying properly, it’s more often than not having to be put on again to finish drying the clothes it should have dried 1st time round.

i’m not over filling it, or putting thick clothes in with light clothes, so not sure why it’s not properly drying and also why it’s squeaking like crazy.

i’ve had the dryer for about 5 years

it has sensor drying, but it’s sensing the clothes are dry, when they are not,(hence having to put the load on to dry again) which is using lots of extra, and unnecessary energy which i cannot afford.
