Question B737NG “PACK” NNC
Question on the PACK NNC:
After pushing the TRIP RESET, if both the PACK lights keep illustrated, why we set R RECIRC FAN AUTO & L RECIRC FAN OFF?

We know that RECIRC FAN could reduce the packs' working load, I guess turn off the fan would reduce the warm air from E&E bay to cabin, but why not turn both L&R fans off?
