Have a 5 year old Liebherr Freezer GN 2566 Index 20B/147.
Temperature started to rise and noticed the frost free unit was in fact frosted up not allowing air circulation. Have defrosted and started again with no cure. Have investigated freezer unit. Door seals and air circulating fan are OK. To try and fix have purchased one temperature sensor although unit has two of exactly the same spec. Question is which one do I replace for the failure mode. Is it the evaporator sensor or the air sensor?
Appreciate any advice please.
