When we bought this house almost exactly 10 years ago we installed all new appliances.
Here's the results:
Kenmore Elite fridge: replaced the icemaker and replaced the fan motor.
Kenmore Elite d/w: replaced the door springs two times.
GE over-the-range m/w: replaced the magnetron
GE dual fuel range: no repairs
These all are high-end though not commercial grade appliances.
Edited to add: I should have also mentioned that the total cost of these combined repairs adds up to well over $1000.
