I've returned a sander after 2 years - it was little used and only
worked upside down. Forget guarantees and remember stautaory consumner
rights. THe person with the freezer - there is no maybe's about you
having a claim. As long as you have not abused the product it should
last 5-6 years and so the shop (not anyone else) should repair, replace
or give your money back. Of course they will say otherwise but ask,
then send registered letter, then small claims.
