For purposes of this section and of section
2302
(c) of this title, the term “without charge” means that the warrantor may not assess the consumer for any costs the warrantor or his representatives incur in connection with the required remedy of a warranted consumer product. An obligation under subsection (a)(1)(A) of this section to remedy without charge does not necessarily require the warrantor to compensate the consumer for incidental expenses; however, if any incidental expenses are incurred because the remedy is not made within a reasonable time or because the warrantor imposed an unreasonable duty upon the consumer as a condition of securing remedy, then the consumer shall be entitled to recover reasonable incidental expenses which are so incurred in any action against the warrantor.
