Plug the machine back in and retest.

Has this resolved the problem?

Change target temperature

The machine will do this if the previously entered temperature is below the current room temperature and above 32F/0°C.

Please change the target temperature to 32F/0°C 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.

Wipe the machine

The following areas should be checked and cleaned to maintain the machine's performance.

Loop amplifier - clean with a dry or damp cloth.

Main body - clean with a dry cloth

Shroud - clean with a dry cloth or soft brush

WARNING: Do not use polish or detergent on any part of the machine.

Troubleshooting image

Has this resolved the problem?

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.

Is there anything else we can help you with?

Please select the appropriate option

Do not use polish or detergent on any part of the machine.

Cleaning required

The following areas should be checked and cleaned to maintain the machine's performance.

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.

Troubleshooting image

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.

Has using the blue thermostat button and changing the airflow resolved the problem?

Troubleshooting image

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.

Test oscillation

Before switching on, please make sure the fan is positioned so that the airflow or oscillation is not obstructed.

We need a little more information to help us solve your issue.

Please contact our customer service team via live chat.

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 feet are attached correctly

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.

Target temperature explanation

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.

Troubleshooting image

Has this resolved the problem?

The use of an extension cable is not recommended.

Reduced airflow

When using heating mode, the machine is working harder to both heat and circulate the air. Whilst doing so, the machine intelligently monitors the current drawn so it doesn't trip the domestic circuit.

The machine will prioritise heating the air, so you may find the airflow feels reduced in heating mode.

Has this resolved the problem?
