Hello. I have a KRC4 controller. An error msg of Outer Fan Speed Too Low is coming up.
I have checked the controller exhaust fan and the fan is not moving.
I have checked the A1-X14 connector on cci board and its working with 24V of signal coming up.
The operational hrs is just 2000hrs and 2.5 yrs in operation.
Controller is placed in clean environment.
We have tried cleaning with blower.
Any way around to start the fan?
