My fridge freezer has just packed in after near enough 20 years.
I think I may have hastened its decline by partially blocking a vent (tho it's not to the interior of the fridge, just to the space at the back of the fridge, and by allowing ice to build up. And then the heatwave really challenged it.
Compressor still hot, very hot, and I can feel a vibration from it which suggests that something is happening, but no freezing.
Wandered into John Lewis where I bought the last one and on saying it had done 20 years, the staff bod said, very honestly, "ah an older generation one".
Said that they only last 5 to 10 years these days. And have read similar elsewhere.
Shocking - I remember when in the good old days and kids were expiring by locking themselves in fridges, they seemed to run forever.
Have ordered a new one but have decided in future to only buy cheap fridge/freezers and take my chance - just get one with a two year guarantee and hope for the best. No point paying for "quality" if you are going to be faced with a bonkers bill to fix.
May even buy cheap second hand in future if cheap and clean.
