"Archers" powerplant continued to give trouble, particularly the electro-magnetic clutches. If the clutch disengaged the engines would race at high revs and had to be shut down in order for repairs to be made. This was particularly problematic if aircraft were flying or there were enemy submarines nearby. On 26 June, "Archer" departed Freetown bound for Bermuda, where she was to undergo repairs. Work started on 15 July and took some fourteen weeks to complete. "Archer" then sailed to New York City where she joined Convoy UGS 2 which departed New York on 2 November bound for Casablanca, Morocco. She ferried 30 Curtiss P-40 Warhawks and US personnel to Casablanca. She then sailed to Gibraltar to join convoy MKF 3 which departed Gibraltar on 27 November. When "Archer" arrived in the UK, she was sent to Liverpool for another refit which commenced on 4 December. Her flight deck was lengthened at this refit.
