Chigo KFR61-IW/X1c-M Error FF

[National]

Hi,

My chigo AC runs for 15 mins then the outdoor fan and compressor turn off. Error code FF is displayed on internal unit.

Has anyone experienced this before? Chigo error codes are a bit vague...

No ice anywhere on the units... pipes appear fine... only issue i can think of is the blower fan on the internal unit has a lot of mould on it.... could this be causing a problem? Filters are clean and so are the cooling fins.

Thanks very much

If the fan is dirty then you will get low airflow through the cooling coil causing low temperature alarms perhaps.

Cheers Brian,

Will give it a try. Will let you know how it goes.
