Electrolux ER3162BN
928405221Been to this recently symptons warm in the fridge. It was frosted in the freezer. Defrosting sorted the problem initally but a few weeks later the same again. Customer defrosted again tested all components all ok, been running for 3 weeks fine but again becomes warm in fridge.
defrost timer possibly?
Re: Lux frost free fridge freezer
has it got a manual timer on it if so then rotate it slowly until it clicks onto defrost and so long as the evap is cold enough the heater should come on easy way to check the operation of heater o/load stat etc. if all is well make sure punter aint leaving door open or seal split air getting in.
Re: Lux frost free fridge freezer
This model has Euroflec electronic control with 2 ntc thermistors, main pcb, display pcb, defrost heater and drain heater. I would guess that either the defrost heater is o/c, or the main pcb or evaporator ntc has failed. You can measure the resistance of the heaters and the ntcs from the foamed-in connectors behind the freezer rear plastic panel. If either of the ntcs fail you should get the 3 leds flashing on the display board.
You can put it into service mode to test the operation of the compressor, fans and heaters. If you want to test the fans be careful; they operate at 18Vdc.
It’s worth getting the TDS offline disc which gives you all the information you need; service mode, faults indication, schematic diagram.
