How do I change heat to cool?

Hi Annette, it's Jack at Dyson.

When you lower your AM05's target temperature (shown on the LED display on the front of the machine) down to 0°, the red light around the on/off switch will turn blue. This shows your machine is now running in fan-only mode, without the heating elements - suitable for use in hot weather. You can then adjust the airflow power and oscillation to suit your needs.

I hope this helps. If you need any further advice, visit and click 'Support'. Or if you'd like to speak directly with our experts, you can reach the Dyson Helpline on 1-866-693-9766 (US), 1-877-397-6622 (CA) 1800 239 766 (AU), or 0800 298 0298 (UK).

My days on heat/ cool fan won't start on cool

Hi there, it's Jack at Dyson.

To run your Dyson Hot + Cool heater on fan mode, you need to turn the target temperature down to 0 degrees using either the remote, or the controls on the base. The target temperature is shown on the LED display on the front of the heater. When fan mode is activated the light around the on/off button will turn from red to blue.

I hope this helps, but if you'd like any further advice you're welcome to contact our experts 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

There is a paper jam most probably in the fuser unit. This causes the heater lamps delay in heating the fuser roller at the required time.

Sharp copier SF-2025 displays an error code H4

H4, not heating up, replace fuser unit complete or work with hivolts and replace an expensive and tricky lamp/thermister . wont be cheap.

. Here use the reset for it first, sometimes power surges can just flip them out but most times will just reappear shortly after reset, indicating the want of a working fuser assembly

Fuser (not fuse) is the hot bit with rollers at paper exit if code fails it needs to be replaced, wont come cheap no matter how you approach it

Sharp AR-M207 Error Message

H4-00 means heat roller low temperature detection. It usuallly caused by 3 things :

1. The machine hang : You simply reset the error code by pressing : # * C * then input 14 then start.
2. If the error still displayed, open the side cover, feel the fusing unit ( don't touch, it is hot ), if the
fusing unit feels cold then the problem is the heater lamp ( inside the upper heater roller,
connected with anti heat cable and big connector ), you should replace it.
3. If the fusing unit feels warm or hot then the problem is the thermistor ( connected with small cable
and connector ), replace it.

Auto shutdown sharp xg-p25x projector

This would seem to be heat-related as these lamps get hot rather quickly. The first quick and dirty solution - try cleaning the filter which is under a panel on the bottom of the projector. Another fix - be sure the projector is plugged into an image source; i.e. computer or DVD player. Sometimes these units will go into standby mode without a signal. More difficult fix - be sure the fan is runningn. When it shuts down, the fan should keep running until the lamp cools, then it will shut down. If the fan isn't working the temperature build-up with shut the projector off. Replacing the fan may be a job for a tech.
