Hi,
I have a 12/800/35 Multiplus that I installed 2 years ago. It is located in an enclosed room.
Instead of the usual fan noise it is now making a whirring sound as if its bearing (or bushing?) is lacking lubrication.
Temperature in the room oscillates between 12 and 28C throughout the year. Current temperature is 26C.
It is installed in my cottage that I visit a couple times a year. I have noticed the noise now during my current summer visit (South of Argentina).
The system is always on throughout the year.
1.Did anyone experience something similar?
2. Do I need to replace the fan? If so, is there a part nr or spec?
3. The multi is installed in a vertical panel, do I need to remove it from the panel to remove the cover?
4. Any recommendation will be of great help.
Thanks in advance
Federico
