Posted · Ultimaker 3 / not starting / switches off after sound of fan

After not using my UM 3 for about 3 months i switched on my UM3 this morning. Directly after switching on i can hear the fan running for about a second but the printer does not switch on. 

Any suggestions?

    There are no components in the UM3 that are affected by time, i.e. no batteries or such components.
    Is it possible a connector came loose? Was the printer moved around during those 3 months?

    I left the printer clean and switched off. Neither moved nor any other mechanical issue. 

    I will try to open it to check all connections.

    Did you check the wire connection to the print head? I have add similar problems and invariably reseating that connection solves it.  You have to undo the two bolts on the top of the print head to get at it.
