David Nielsen started the season as the manager, but was sacked after league round 10, having only secured 12 points. He was replaced by assistant manager Bjørn Petter Ingebretsen on 26 May 2015. Ingebretsen achieved immediate success, and took the team from 9th to 2nd after a 20-match run that secured 45 points.

In the cup they were knocked out by 2. Divisjon side Kvik Halden on a penalty shootout in the third round. In the UEFA Europa League qualifications, they eliminated FK Partizani and FK Mladá Boleslav in the 1st and 2nd qualifying rounds, but lost 0–4 on aggregate versus Hajduk Split in the third qualifying round.

Three important players left in the winter transfer window, as well as several players who had been on loan spells.

Former Ghana international Adam Larsen Kwarasey, who had been in the club since 2007, and was the first choice goalkeeper for the last five seasons, signed for Major League Soccer club Portland Timbers after his contract expired. He was replaced by the experienced former Norway international Espen Bugge Pettersen, who had become back-up goalkeeper at Molde in the two previous seasons.

In defence, former Norway international Jarl André Storbæk , who had arrived mid-season in 2012 and been crucial to the title win in 2013, left the club after his contract expired, to become playing assistant manager for Nybergsund. He was replaced by French left back Florent Hanin, who had been released by Lierse.
