Fridge been fine for years, then just defrosts itself overnight, possible door open ? We empty the wasted freezer goods, then switch off to clean. After 24hr switched back on, left for another 24hr to get to temp, just warm air circulating, no frost forming on the coil, all fans & lights fine, however, heard clicking noise near compressor, which is warm/hot, but no noise and no cold air being produced. The starter unit/block, on closer inspection has fused inside,pieces of plastic and a circular disc are shattered.
Is this repairable please, everything ran fine for years, then sudden defrost = the end ?
