Key 109 fan feedback exception

If you live in a country with a 110-115v power supply then make sure you flicked the voltage selection switch to the 115v position.

my country 230V and error after 1 week

I would therefore recommend contacting Customer Support to see if they can help you resolve the issue. It could be a faulty part and if so they will replace it for you.

The customer service email is: cs@creality.com
