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.
