Amazon warranty for thermostats
The short version
Amazon doesn't cover everything, but keeps whole product covered to 1 year. That full coverage is the same as most of the 5 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Amazon's published warranty, checked October 2026.
