Products are often cheap enough that the labor costs are too high compared to getting a new unit. It would generally work for appliances that are built into a house or hard to transport because then the relative cost would be offset by the cost of labor to remove and install a replacement.
For example, people generally wouldn’t do this for a TV when they can get a decent replacement for $300 new.
