I have a City Multi R2 Outdoor unit type P450-YJMA. I have the fan board with defect which needs to be changed. The part can not arrive in time and the unit needs to be in running mode. If i install a fan board from another OU type P250-YJMA and disconnect one of the fans, do you think it would work? I can reduce the capacity of the P450 since only half of the units are working momentarily and I have an outdoor temp. from 31-35C. Any quick though is appreciated.
