My cheap space heaters have lasted me for upwards of a decade but my Dyson AM09 received an H2 error code and no longer functions. Based on what ive read, Dyson won't actually help with the issue. Save yourself the trouble, get something better.

This fan worked very well, heating and cooling our bedroom for a year, until it stopped working, and Dyson provided no ways to get it repaired. A shortcoming with this fan is that there is no filtration for air flowing through this unit. As a result, dust and debris will accumulate over time. In our case this affected the fan's heating function, prompting an H2 error. We attempted every troubleshooting step provided on Dyson's website to no avail, and ultimately we were unable to get this unit repaired because the problem occurred 4 months outside of the 1 year warranty period. So we were told by Dyson that our only option was to buy a new unit for full price. But I do not have confidence a new unit will even solve this problem, as debris will build up again, and it is very difficult to clean the inside of this unit. I really wish this fan worked out as it did for our first year, but it appears these are not build for longevity, and once your warranty period ends there is no way to get it fixed.

I bought this fan Oct 2021. It completely died Oct 2022. Although it has a great warranty and I've generally been happy with the fan, I'm extremely frustrated to be waiting 2 months for a replacement -- of course, it's winter and I specifically bought the fan for the colder areas of my home.
