Dyson Hot+Cool™ fan heater (Black/Nickel)

Let's get your machine working.

Run heater at highest temperature

The heating elements turn on one at a time and so this is to be expected when the machine first turns on.

Run the heater for 1 minute at the highest temperature setting.

Paper test

Turn the airflow control to maximum.

Hold a sheet of newspaper approximately 3 meters (10') away from the product.

The paper should lift beyond 45 degrees.

Please follow steps in the video.

Check and clean machine

Loop amplifier - clean with a dry or damp cloth.

Shroud - clean with a dry cloth or soft brush

Try the paper test again.

Target temperature

The temperature set on the machine is the target temperature of the room, not the temperature of the fan.

The temperature from the fan when in heating mode will not change.

Enable cooling mode

Unlike the AM04/AM05 the AM09 does not need to be set to 0°C to enable cooling mode.

Turn the machine on.

To turn the heater off and use cool air mode press the BLUE Thermostat Control button. The power button light on the main body will change from red to blue.

Change the airflow speed using the Airflow Speed Control.

NB: The fan speed setting is between 1-10.

Retry machine at 37°C

On first use, the heater will default to a temperature 1°C higher than the current room temperature.

Thereafter, the heater will remember the last target temperature set.

The heater will not operate unless the target temperature is above the room temperature.

Please retry the machine at temperature setting 37 degrees.

Press the red thermostat control button until the digital display on the main body shows 37 degrees.

The power button will turn red for heating mode.

Each time heating mode is selected the machine conducts a short calibration cycle, during this the airflow will be automatically controlled, once the cycle is complete it will revert to the selected airflow speed.

Oscillation range

The machine should oscillate within 70 degrees from one side to another.

Oscillation speed

The machine should take approximately 4 seconds to oscillate from one side to the other.

Normal oscillation speed

The oscillating speed is normal.

Checking oscillation

The AM09 has a one touch smooth oscillation action.

When in oscillation mode the machine will temporarily stop oscillating when any of the control buttons are pressed.

If the oscillation doesn't work carry out the following checks:

Check the six feet on the base of the main body are present and clean.

(If the heater is placed on a low friction surface, e.g. highly polished or oily, the main body may slide)

Switch the heater on. Press the oscillation button.

Check the other remote functions are working and that the battery has not run out.

Try a 'Hard reset'. Unplug the machine at the wall and leave for two minutes before plugging back in.

If the other functions are not working send a new remote.

If the oscillation action is still not working arrange an exchange.

Check remote

Check if the other functions on the remote are working.

If the remote control is not working but the button on the machine is, please select 'Remote control not working'.

Check remote is being used correctly

Please ensure that the remote is facing the correct way and has a clear line of sight to the base of the machine.

Replacing remote control battery

Unscrew the remote control battery lid.

Remove battery and replace it.

Re-insert and test the remote control again.

Test remote

Squeeze on the remote control below the buttons and operate one of the functions.

Camera test

The remote LED is invisible to the human eye, only a digital camera can show this is working.

Using a digital phone or camera, aim the LED at the lens and see if a red light shines through it.

NB: This check will not work for iPhone 5s or 6.

Move obstructions

Please retry the remote with the machine again, ensuring no obstructions.

Replace battery

Please replace the battery in the remote and call back if the problem persists.

Replace batteries

Replace the battery in the remote control and call back if the problem persists.

Replace the battery with type CR 20

Test airflow

Switch the machine on using the remote control or button on the main body.

If the airflow control is still not working this issue can be resolved by arranging a return to base repair.

Press the airflow control button (2) at the top and bottom, whilst testing the airflow.

NB: The display will show 10 after the product has reached maximum, or 0 for minimum airflow.

Check the other functions on the remote

On/Off

Cool air mode

Airflow speed control

Temperature control

Sleep timer function

Oscillation On/Off

Personal heating mode

Diffused heating mode

Replace batteries

Unscrew the remote control's battery compartment.

Loosen the base and pull it away from the remote.

Replace the battery with type CR 20

Replacement remote required

This issue could be resolved by ordering a replacement remote control.

Intermittent power

If the machine has been constantly heating for 9 hours, please select yes.

More than 9 hours

Dyson fan heaters and hot and cool purifiers have a positive safety feature where the machine deliberately switches off after 9 hours of continuous heating.

If you would like to continue using the machine after 9 hours, you will need to turn the machine back on by using either the power button on the remote control or main body.

Turn machine off

Please turn the machine off and back on again.

Check feet

The AM09 has a one touch, smooth oscillation action. When in oscillation mode, the product will temporarily stop oscillating when any of the control buttons are pressed. If the oscillation action doesn’t work carry out the following checks.

Check the six feet on the main body are present and clean. (If the heater is placed on a low friction surface, e.g. highly polished or oily, the main body may slide.)

Check remote

Switch the heater ON.

Press the oscillation button.

Check the other remote functions are working and that the battery has not run out.

Try a ‘Hard reset’.

If other functions are not working order a new remote.

Please check the following

Fuse in plug.

Household electrics.

Unplug the machine, plug back in and ensure the power button on the machine is being pressed fully.

Hold for 2 seconds.

Use the buttons on the machine, not the remote control.

If the remote only isn't working, please select 'Remote control not working' from the drop down list.

Change target temperature

The machine will do this if the previously entered temperature is below the current room temperature and above 32F.

Please change the target temperature to 32F and retry the machine.

Use the buttons on the machine, not the remote control. To use as a heater please select a temperature above the current room temperature.

If only the remote isn't working, please select the 'Remote control not working' from the drop down list.

Reset machine

The display will show a fault code and the LED around the power button will flash red.

Idle mode

The AM09 will switch into idle mode once the target temperature is reached, idle mode means the motor is running at a lower rate than when in use to keep air flow moving over the thermostat so that the machine knows when to switch the heating mode back on.

If you are near the machine they may feel a draft coming from the machine when it is in idle mode.

Check the electrics

Check that the household electrics are on.

Change the fuse in the machine's plug.

Check the plug and power cord for signs of damage.

Try the machine in a different plug socket.

A red light indicates the heater is in use. The machine is working as expected.

Machine is working

This is normal and the machine is working as expected.

Machine is working normally

This is completely normal.

The machine will run very slowly when in idle mode to keep air flowing over the thermostat so it can constantly regulate the temperature of the air.

This is a characteristic of the product and cannot be resolved with an exchange or return to base repair.

There is no safety concern.

If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.

Checking the loop amplifier and shroud

Check the air inlet holes and loop amplifier for blockages and remove as necessary.

Use a soft brush to remove any debris.

To clean, wipe with a dry or damp cloth.
