I HAVE A HOTPOINT RFA16 FRIDGE FREEZER, THE FRIDGE IS TO WARM AND T FREEZER IS FINE, ANY IDEAS

It sounds, as though, something could be faulty with your defrost. Before you do anything with that, be sure, that the air vent into the refrigerator isn't blocked. Cold air moves from the freezer into the refrigerator, which provides the cooling. Check your evaporator. See if it is frozen with a massive amount of ice. It is in the freezer behind a wall, where the fan is. Now, back to the defrost. Most of the time, it could be one or two problems. The first could be the defrost heater. It is located within the freezer. It is close to the evaporator. It heats up during the defrost cycle. To tell, when the defrost cycle occurrs, the evaporator fan will shut off, as well as, the compressor. Nothing but the interior light/s will come, once you open the door. The other problem could be, that the defrost control is bad. It triggers the defrost cycle. It is a timer, really. It slowly spins. In some cases, the timer motor stops running. If you can locate the defrost control, it will have a stem, which can be turned with a screwdriver. Turn it and see, if the box goes into a defrost? If it does, great. Defrost cycles vary in length, depending on make. Wait, for up to one half hour, if the box doesn't come out of defrost, I would say, that the control is bad. If it does come out of the defrost, great. Now, place it back into defrost, and check the heater. Be careful and don't get burned! The heater should get gradually hot. If it doesn't, the heater is bad. If you know how to use a OHM metter, use it. I hope this helped? Good luck.
