Ensure fermenter lid is screwed down tightly. Indicators of fermentation are: condensation inside the lid, frothing/bubbling of the surface of the wort and a ring of scum on the fermenter wall above the wort. Fermentation can be verified by removing the fermenter lid and examining the wort. The wort may actually be fermenting, but the CO2 gas will be escaping through the faulty seal. If the airlock grommet and/or fermenter lid is not sealed then there will be no active bubbling through the airlock.

Move the fermenter to a warmer place (18-23☌) and rouse the yeast by stirring the wort with a sterilized spoon. Pitching the yeast into wort that is too cold or allowed to become too cold may prevent fermentation or significantly slow down fermentation.
