The one with the cooling tray fan always on as a SN around #3500
and the other on around SN#6300
Both machines have latest stable firmware
Both have original cooling tray fans
So why?
Which cooling fan are you talking about?
Cooling tray fan,
Exhaust blower (for drum airflow)
Coil fan 1 (fan underneath the Bullet)
Coil fan 2 (small fan visible when you remove the chaff filter)
Can you see the RPM in RT? Does this change when the induction is at P0 or P9?

Hi @grrr,
We’d recommend contacting [email protected] for further diagnosis for privacy reasons as you might need to share some videos. You might have a connection issue with the PWM pin but we want to be 100% sure by looking at how it’s currently working.
Best regards,
Kevin
