I have a dyson DC 3.5 model 11-6300 d1 it will run about 30 sec then shut down the green light will keep flashing whenever I tried to run it then shut down

If this is a cordless vacuum model then the battery is failing.

Could be a bad battery that needs replacing.

It needs a replacement battery or check the output of charger, may need to get an electrical experienced person for this with an volt meter

Google Dyson. co On the drop down window, find your model, type in Dyson DC 24, at bottom of page click on shopping info, click parts. you can order from there.

clean all access ports up the handle. plugged somewhere.

what is the shroud ?

yes the reason the green and red light were flashing the way they are is because its a warning to you that the battery is either no longer good or there is problems with your wireing. Also those vaccumes were designed to not charge when there to cold or to hot as a saftey issue.

take it apart and look for some trash might be rapped around the motor,because if the motor heats up it will shut down to keep it from burning up
