The effects of thermal fluctuations on the evolution of the scalar field in a preinflationary period are explored numerically to complement a previous analytical investigation. The analysis is applicable to a weakly coupled scalar field in a double-well potential in new inflation. A critical value of the strength of the coupling to the thermal bath is found, above which thermal fluctuations do not allow the inflationary period to begin. The evolution of the scalar field is followed until the onset of the inflationary period.
