Yes you must unsolder the end temperature control ***** and ensure they are no longer connected to the board. Then very gently remove it from the temperature control ***** and eight retaining clips. On reassembly ensure the speed control **** now realigns. It is keyed but can cause problems on reassembly due to alignment with the new potentiometer, . I bent the three legs on the new potentiometer to ensure it was in the same exact spot as the old one to aid in alignment.
Hope this helps.
