I have a Maytag Trilogy fridge freezer - model: G32026PEKB The compressor blew and has been replaced but does not cut out Advice please Nigel Winter

If the compressor runs continuously is everything freezing? If the compressor is running and it is not cooling the problem could be a refrigerant leak in the system. Visually check points where new compressor was brazed into place. Any sign of oil at these points indicates a leak. How long ago was the compressor replaced?
