There is no "reset" button, it will reset by turning off the switch for 10 sec or so, then back on. It tries to light for about 10 sec then warps off if it doesn't light. Yours is not lighting, prob dirty pilot. Open the little door on the front of the big vertical chimney in the refrig control box outside, blow it out with air or try a toothbrush to clean it off. It may be out of adjustment too but usually just dirty or the air adj is out of place.
