Danny Schofield had just one win in nine games in charge of the Terriers.
The Terriers finished third in the Championship and lost in the play-off final.
They lost seven of the nine matches they played and are now in danger of being thrown out of the league.
The club thanked Danny for his hard work and dedication and wished him well for the future.
The team will be led by coaches Pelach and Harsley.
In February 2020, he returned to coaching as a player.
According to Dean Hoyle, the club had always intended to make him head coach whenever Corberan left, and that he almost took another job in Europe at the end of last year.
Danny was offered a job on the continent. As sad as we are to have lost Carlos, we are thankful that we kept hold of Danny because he was the heir apparent.
The Terriers became the second Championship side to sack their manager this season, after the Potters parted company with Michael O'Neil in August.
