A service contract or warranty usually has a coverage list and an exclusion list, and both decide what you can expect after a failure. The coverage list is the one read aloud in the sales talk. The exclusion list is shorter in the talk and longer in the paper, and it is the one that decides most disputes about a denied repair.

Exclusions often appear in a section after the coverage grant, sometimes under their own heading, and sometimes in a schedule or endorsement attached to the main form. Check every attachment. Read the paper from the first page to the last, including the small print on the back and any addendum that says it changes the terms.

What to look for

Wear items, cosmetic damage, damage from outside causes, commercial use, conditions that existed before the contract started, and repairs made by someone other than an approved provider are common headings. Not every contract uses these headings, and the wording may differ. Find the sentence that matches each situation you care about, and do not assume a heading covers a case it does not name.

Questions to ask before you sign

Ask the seller to point to the exclusion that applies to the part you worry about most. Ask whether that exclusion turns on the cause of the failure, the age of the part, the hours or miles of use, or who performed the work. Ask whether an exclusion can be removed by paying an extra charge or by choosing a different plan. Ask what happens when the paper and the seller's description disagree. Get each answer in writing and compare it to the clause it refers to.

What to mark

Mark each exclusion with the words you would use to describe your own household. Put a second mark beside any exclusion that depends on something you control, such as maintenance records, the choice of shop, or whether you open the unit yourself. Those are the lines most likely to matter after a failure.

If the exclusion language is unclear, ask for it to be restated in plain words and keep the reply. A clear answer from the seller does not change what the paper says, so the text controls. The regulator named in the paper is where an unresolved question goes. The state pages in this index set out the rules that apply in each state, cite the statute or program, and say whether a roster is printed in full.
