Display works but no heat

All controls work, the heater even 'shuts off'(audible click) if you lower the target temperature to below the ambient, but no heat at all from unit.

Keep in mind that this unit will take a while to heat up. I have the same unit and it can take up to an hour to get really hot. Once up to temperature, you should hear the thermostat cycle on and off. To test it, set the thermostat to a low setting and leave the unit for an hour. It should be warm. If it is not, then the problem is after the thermostat such as a broken heating element wire. If so, it is probably not worth fixing.

SOURCE: Incorrect ambient temperature on Honeywell Model RTH221B

Check in your manual for the thermostat. By pushing a combination of buttons you can get into the advanced installer menu. From there you can make an adjustment to correct the temperature.

My dyson won't turn on. In the section for the speed of fan is showing the number 33.


Hi Deborah, it's Jack at Dyson.

It's likely the '33' you see displayed on your machine is the target temperature you've selected, as the fan speed goes from 1-10.

If you've selected 33 degrees as the target, your heater will only activate if the ambient room temperature drops below 33 degrees. It would then continue to run until the temperature reaches 33 degrees once again. The intelligent thermostat is engineered to heat the room to the desired temperature, then to run as needed to maintain this temperature.

If you want the heater function to run, try increasing the target temperature degree by degree until the machine comes on. But if you want to use the fan-only function in warmer weather, turn the target temperature down to 0. The LED indicator around the on/off switch will turn blue, and the machine will run in fan-only mode to cool you down with unheated airflow.


I hope this information helps. If you'd like further help or advice from our experts, you're welcome to call the Dyson Customer Helpline directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Why does it work OK all evening then a quiet motor sound but no blow. Cause=?


Hi there Philip, it's Jack at Dyson.

When your Dyson Hot + Cool heater has heated the room to the target temperature you've chosen (shown on the LED display on the front of the machine), it will revert to monitoring mode. In monitoring mode, the motor will continue to run at a low speed, drawing a small volume of ambient air past the intelligent thermostat. When the thermostat detects that the ambient air temperature is falling below the selected target, the heater will activate again to maintain the temperature.


From your description it sounds as if your machine is working correctly - it would display an 'E' or an 'F' error code on the LED display if there was an actual fault. However if you're still concerned I would encourage you to contact the Dyson Customer Helpline directly for further advice. You can reach our experts by calling 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

My dyson fan was serviced last winter by you as it was recalled now it does not work , the lights come on and the motor runs 2 seconds and dies


Hi Kathy, it's Jack at Dyson.

I'm sorry to hear you're concerned about your Dyson fan heater. However, this could be normal behavior from your machine, as the heater would usually display an error code if was an actual fault.

If the target temperature you've selected (shown on the LED display on the front of the machine) is equal to less than the ambient room temperature, the machine may run momentarily until the intelligent thermostat shuts it off.

The solution is to raise the target temperature, using either the remote or the controls on the base of the machine, until the heater runs. It's important to keep in mind that what you're selecting is the temperature you want the heater to heat the room to - so the machine won't run if the room is already at or above the target temperature.

I hope this helps, but if you'd like to discuss this with one of our experts you're welcome to call us directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Dyson hot and cold


Hi there, it's Jack at Dyson.

It sounds like your heater is shutting off because the ambient temperature is higher than or equal to the target temperature you've chosen (shown on the LED display on the front of the machine):
The heater's intelligent thermostat is engineered to turn the machine on only when needed when the ambient room temperature drops below the target temperature. However, we're happy to help you make sure your heater is working as intended. Please give us a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

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.

The Getting started guide I've attached may help, but if you'd like any additional advice from our experts you can reach us on 1-866-693-9766 (US), 0800 298 0298 (UK), 1-877-397-6622 (CA).

Dyson fan heater keeps shutting off


Hi Deb, it's Jack at Dyson.

If your AM04 fan heater runs for a few moments then shuts off, this is likely to be because the target temperature you've selected (shown on the LED display on the base of the machine) is lower than the ambient room temperature. The intelligent thermostat is engineered to ensure the machine will only run as needed to maintain the target temperature you've chosen.

Using the remote, or the controls on the base, to raise the target temperature by a few degrees should resolve the issue. I've included our Getting started guide below which shows how to adjust the temperature.

If you would like some further help from our experts after you've given this a try, please call 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

My dyson hot fan will not give out air under 24 degrees?


Hi Charlie, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 24 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 24 degrees. The heater will only turn itself on if the temperature drops below 24 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

I've attached our Getting started video below which shows how to adjust the temperature, using the remote or the controls on the base.

I hope this makes sense. It sounds as if your machine is working correctly, but if you'd like any further advice from our experts you can reach us at 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Dyson hot and cold fan only works in hot mode


Hi there, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 25 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 25 degrees. The heater will only turn itself on if the temperature drops below 25 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

Projector heating up and bulb shuts down


The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work
get a small fan and place it near the projector to provide
extra cooling. The projector is running border line on
high temperature and just needs a little extra cooling.
