GE fridge not cold enough

Geoff asked 4 years ago
Fridge and freezer not cold enough. Set on max cooling, but not coping.
Compressor very hot – I think it’s running non-stop. Condenser is warm.
Fans underneath and in freezer are running.
Light goes off when fridge is closed.
Nothing blocking air outlet in freezer.
Removed as much dust as possible – no difference.
Fridge is about 15 years old – ran fine until now. Top freezer.
