Irregular temperature increase

[rezjat]

Hi.

Since some weeks ago, I observe that when starting temperature increase towards its target, from around 150º it start to show a quite irregular curve (up and down values), instead of a smooth curve as It was before.
But once it gets the target (in a very irregular way), it works normally...

Any suggestions? Is it a signal of thermistor starting failing? I disconnected connectors at main board and connected again but no differente...

Thanks a lot!

Hello, it may be that the thermistor is not too sensitive, but if it can be used normally, don't worry.
