Hi.
Yesterday I´ve done some measurements at the thermal switch.
My unit has "93-ON" stamped on it (I think it means "turns on at 93°C") and found that it turns on over 94°C, and opens back when under 77°C:
My OEM temp switch:
Switching from open to closed (when the fan turns on):
Switching back from closed to open (fan off):
Regards,
