Strange Heat Bed temperature curve

Hi,

since some days I recognize strange drops in the temperature curve of my heat bed. .
What do you think: Is the cable of temperature sensor broken, is the temperature sensor itself broken or is this something else?

Best regards
Holger

The cost of replacing the thermistor and cable is negligible, so that's what I would do first.

What kind of printer is this on?

I agree with Phaedrux.I was having the same issue and it was caused by a bad solder joint/connection on the thermistor wiring.

Hi,

thanks for your replies. Yes - the cost or a sensor is not high but it is mounted between cork and the 230V heat plate. So I will first replace the cable as far as possible and hope that this will help

Best regards
