Dyson hot cool will not start

Hi Frank, it's Jack at Dyson.

I'm sorry to hear you're having difficulty with your Dyson Hot + Cool fan heater. I'm not sure from your question if your machine isn't running at all, or if it's displaying an error code. However, there are a couple of quick troubleshooting steps you can try.

If your AM05 is displaying an error code, we'd recommend unplugging it for the wall socket for 30 seconds before testing it again. This should reset the machine.

However, if your AM05's LED display lights up as normal, it may not be coming on because the thermostat's target temperature is set lower than the current ambient temperature. Try raising the target temperature degree by degree using the remote or the controls on the base. You should find it will come on once you've set it to heat the room to a higher than ambient temperature.
