Hi, I have a Hotpoint NCD191 fridge which is running continuously and frosting up at the back, however it is not getting below 10 degrees centigrade (50f). I have cleaned the coils and changed the thermostat and checked the door seals. The fridge does not cut out when the thermostat is frosted up! I assume it is a defrost timer or heater issue but can not find one. The fridge is a sealed unit at the rear with the evaporator coils covoured by insulation. There is no circuit board or PCB si I assume there must be a defrost circuit. Is anyone able to advise where this is likely to be and how to fix it.
Hi, I don’t know the model but looking at the parts for it, it seems as though it has an evaporator fan (example only) or at least that’s how it’s described so it is not a condenser fan near the compressor. Check if you can hear if it is running. Normally evap fans run as long as the compressor is running and the door(s) are shut. Opening a door will stop the fan and it will start again when the door is shut. The fan blows the air across the evaporator to cool things down to the set temp. If you can’t hear it then the fan may be faulty or iced up i.e. defrost problem or it may be a door switch problem. Check if the light in the fridge turns off/on when you manually operate the switch with the door open (This is assuming that the switch is located in the door jamb somewhere and is visible).
