What warranties usually cover
Coverage varies, so read your terms.
Defects in materials or workmanship
This is the core of most manufacturer warranties.
Parts vs. labor
Some warranties cover parts only after the first year. Check whether labor is included.
In-home service
Large appliances usually get repaired at your home. Smaller ones may need to be shipped.
Replacement
If repairs fail repeatedly, some warranties allow a replacement. Read the conditions.
