Hi, is there anyone who can advise me regarding hotpoint FF187L fridge freezer, there is lots of ice building around the heater, I have changed heater and thermal fuse still ice building, if I defrost it by switching off then works for 3 weeks, thank you.

If you've replaced the heater, then a defrost is not being initiated. Therefore the controller may be faulty.
It could also be the evaporator sensor faulty, terminating the defrost either immediately, or prematurely.

hi thanks for you reply, hotpoint supplied sensor with heater, its call thermal fuse that fits on heater.
Thermal fuse sounds like a safety device / overload / fuse for the heater - odd term they've used!
As I said, sounds like the controller or evaporator sensor (which has nothing to do with the heater or what they call the thermal fuse). Remember, it's hard to remotely diagnose these things without being there and actually looking.
All we can do is guide you hopefully in the right direction.

If you are are able to test the defrost thermistor (white bullet which clips onto the top of the evaporator)may be wrapped in foil. By unplugging the connection from the pcb.. in the top console ..usually two thin red blue or black blue wires you should measure 20 odd thousand ohms. Depending on temperature. Any massive variance could indicate that the thermistor is causing premature exit from defrost.
Before contacting Hotpoint who should be able to cut the thermistor out and reprogramme the software to run a timed defrost try
carefully check the white cover, the end cap may have come out causing frost to develope inside the thermistor case . Try drying it out thoroughly before using a suitable sealant to reseal the end cap back. The thermistor is not available as a spare and maplins don't sell a therm with the correct calibration.

there are only 4 component in freezer compartment.
1 heater
2 thermal fuse, square inch box that sits on evaporator that linked to heater
3 fan
4 temperature sensor, that sitting on the floor under the draw, that control freezer temperature
when thermal box get covered by ice its closes and switch on the heater, but there is no power coming to thermal or heater, to me PCB look faulty.

you right, there is thermistor on top of evaporator, I have found it, but there is three connector on PCB and all have black ,blue and red, no idea which goes to thermistor.
