Unless you have "Nordic Mini 3" for 240 V, all other types of Nordic sauna are more than 5000 Watt which means that their rated current for 240V is more than 30 A. For 120V it is two times more.
I don't know your type of Nordic, the rating of the fuse and what voltage are you using, but it may be less than the needed rating. Check the rated voltage and current of your sauna heater.
If your voltage is equal to the rated and the rated current of the sauna heater is less than the rating of the blown fuse, you may have short in a part of the heater.

No, the timer should not make any noise. The noise should be a result of loose connections which cause arcing, which can make a humming or buzzing sound.
If you find that you still notice the sound, even when the main breaker is off then the problem is not electrical in nature.

The Sharp Air Conditioner Remote Control CRMC-A310JBEO comes with two timer-related functions: TIMER ON and TIMER OFF. To set the timer on the remote control, press the Timer button, then use the Temp + or Temp - buttons to set the desired time. Wait 3 seconds, then the timer function will be activated. You can turn off either function by setting its timer to "0.0h".
Try a Power Reset. Disconnect all mains power to it for 15 minutes, press and hold any button for 1 minute. Reconnect the power. If that doesn't fix it, the thermostat has failed and you need a new one. Most have backup batteries that can cause the issue you are seeing, but the manual doesn't mention anything about batteries in the base unit.
