Not as warm as when new

Hi there, it's Jack at Dyson. It would be very unusual for there to be any change in warmth in the heated airflow exiting the machine, as the PTC ceramic plates always operate at the same temperature in heater mode. However we're keen to help you check your AM04 is working as well as it should be. When you have your machine to hand, please call our experts directly on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU). We can take you through some simple troubleshooting checks, and if a repair or replacement is needed, we can confirm if this is covered under our 2-year warranty. We'll look forward to speaking with you.

Heater won't work

Hi there, it's Jack at Dyson. AM04 has an intelligent thermostat which you can set to the degree. The machine will then monitor the room temperature and cycle on and off as needed to maintain the temperature you've chosen. If the heater doesn't seem to be running, it may be because the temperature you've selected is below the current room temperature. When the room temperature drops below the temperature you've picked, the heater should come on.For additional troubleshooting to check your machine is working correctly, you might like to visit our Support page:http://www.dyson.co.uk/support/am04/am04-whsilI hope this helps, but if you'd like any further advice, please give us a call.

Dyson Am04 model no longer turns on due to a power surge. What part is required to fix it? TIA.

First thing is to check the wall socket. Use a desk lamp or something similar and plug it into the socket you use for the heater. If the lamp works so does the socket. Next check the fuse. UK machine have a fuse in the plug, other countries use different systems. If all these check out OK the surge may have damaged a circuit board inside the heater. Only a Dyson specialist could help you with that.

DYSON AM08 PEDESTAL FAN HAS OPERATED FLAWLESSLY FOR TWO YEARS ! TODAY I STARTED IT , IT RAN AS USUAL THEN QUIT AFTER A MINUTE. I TRIED AND SEARCHED FOR A CAUSE FOR AN HOUR FOUND NOTHING UNUSUAL. WHAT COULD BE WRONG?

Probably the bearings are dry. remove the fan and housing to get to the shaft and oil it. The circuit breaker is shutting it off because it is drawing excessive current.

My dyson hot and cold fan is displaying code C2 and won't turn on or off

quote from amazon site***Mine also showed H2. I had a suspicion that it was the remote causing it. Changed the remote battery (CR 2032), turned on the heater and let it circulate for 3 minutes, then I went and tested all remote buttons. It worked! No more H2 error code!
