UM Original. Heater Block not heating.

[keira 0]

I've had no problems with my Ultimaker Original until now.

When I go to print, the temperature remains at 23C (in Cura). I don't think it's a problem with the temperature gauge as when I try to touch the heating block (to test if it is hot) it is stone cold.

Any ideas, anyone?

Thanks

did you check if the heater is still properly connected to the the UM board?

Yes I've checked that the heating block is connected to the UM board. It was fine.

Disconnect the 2 heater cables from the 2 green terminal blocks and measure the resistance of the heater element with a multimeter: you should measure something very close to 9 Ohm... if you get 9Ohm, your heater is ok, and the problem is something else. if you don't get 9 ohm, the heater or the cables to the heater have a problem.
