I’ve noticed over the last year of owning my unit, the demand fan has slowed down. It used to spin really fast about 10-15 seconds after starting and now you can nearly hear it when it does.

The machine is running fine and it’s always puffs a cloud of dust out of the radiator when it starts but just wondering if this is a solenoid replacement issue or a run a calibration on the system issue.

Thoughts?

Thanks,

Brian
