Abstract: In a hermetic compressor there is provided a resilient retainer member adapted to removably secure a thermal overload protector relative to the compressor casing. The overload protector is arranged in a housing which is adapted to engage the upper wall of the casing. The retainer member includes one end portion dimensioned to engage the housing whereby downward pressure on the retainer member secures the overload protector relative to the casing. The overload protector housing is formed to include a pair outwardly projecting leg members. A slot formed on one of the legs aligns with an opening in the other leg are engageable by a tool which is employed to exert an external force on the housing sufficient to allow removal and replacement of the thermal protector housing relative to the retainer member.
