The controller cannot be switched on.
• Check if the controller has been connected to the switch cabinet of the kiln.
• Check if the kiln is connected to the mains supply.
• Check the micro-fuse on the switch cabinet of the kiln. This has a T 2A fuse.
• Have your house mains supplies (plugs), fuses and the current consumption of your kiln checked by a qualified
electrician.
The controller displays an error message.
You will find the relevant explanation in your user's manual for the controller.
The firing chamber does not heat up.
Check if the safety door switch is working. The safety switch is probably not working and thus cannot operate the
safety contactor. Make sure that the safety switch works correctly. If this is not the case, or the door is not fully closed,
the safety circuit is interrupted and the kiln cannot heat up.
The kiln heats up very slowly.
The kiln does not reach the programmed temperatures. The controller displays an error message. Check the heating
elements for visible damage, e.g. cracks.
The functionality of all ROHDE kilns is tested before they leave the factory!
