14 flashes is a fault code. You need to determine which light is flashing and look at an online Mitsubishi fault code analysis chart for your model. The light(s) that flash determine the fault. Power, defrost, timer light flash all mean something different.

It is, more than likely, that it is not coming from your unit. Is someone burning candles? If they are, please stop burning them and use a candle warmer instead. The burning flame of most of the candles today, produce a lot of very unhealthy pollution in the soot that they produce, not to mention the health aspects to you. Scented candles are the worst. The unit usually gets blamed for picking this up and redistributing the particles back into the air.

It's likely being overworked and therefore growing mildew on the fins. Clean the filter and rinse the coil with mild soap/water mix. Wipe down the unit with a damp rag.
