This side by side F/F, triple thermostat, has developed a very mysterious fault that so far has beaten all of the engineers that have looked at it.
Fridge side works perfectly. Compressor runs, fans run, temperature regulates etc etc.
Freezer side: If select 'super freeze' (which lasts for 150mins), fan runs and freezer rapidly reached temp of -26C. After 'super freeze' finished, temperature in freezer slowly gets warmer (-2C within 2 hours) before fan starts running again, which then switches off at around -8C, even though freezer is temp set to -25C. Problem here is that door only needs to be opened two or three times before food starts to defrost!
So far, engineers have replaced F sensor, D sensor, PCB Mainboard, dryer and cleaned and re-gassed - none of which has worked - and are now scratching their heads!
Anyone out there any ideas? Also, does anyone know what the 'default' setting should be for the FRS2031 or how to enter diagnostic mode? The engineer manual (thanks Nike123) gives two methods of entering self diagnostics. The first (Lock on, Hold Freezer Set, Press Refrig Set 5 times) actually enters forced defrost mode and the second (Lock on, Hold Refrig Set, Press Lock 3 times) does nothing. Have found, however, that Lock on, Hold Refrig Set, Press Super Refrig 10 times and Lock on, Hold Sleep, Press Freezer Set 5 times, both give loads of engineer setable parameters but engineer manual doesn't cover what they are or what they should be.
Any help would be much appreciated.
