Cooler not dispensing: This often happens in summer and it is because the cooler is somewhere warm. The cooler reads the ambient temperature and thinks it needs to keep cooling, so it ends up freezing the water inside. Solutions include moving the cooler to a less warm area, unplugging the cooler at night so it can thaw or attaching a "christmas light" timer to the plug to do this for you. On many coolers we can also adjust the thermostat.
