Intermittent blower motor noise??
Hi all,
After replacing the blower fan unit last Dec, i'd been using the EC mode and low fan speed all the time and it works fine.
Last week on a very cold morning, around -20, my wife was taking the children to school and she called saying that there's noise coming from the fan that ran in non EC mode. Now this intermittent, sounded like a bad bearing noise, occurs whenever the Auto fan speed and non EC mode was selected.
The question is why it doesn't come in EC mode + low fan speed?
Any suggestion?
Thanks and have a nice day.
John
