Unfortunately these units are not user fixable , beyond checking for power and checking battery in remote. You would need to call a pro who is able to get service information and has special digital logic meters to diagnose and repair .

An EO error indicates an electronic error caused by either a control board problem or a problem with supply voltage to the heater. A single EO code is not cause for concern, but for repeated EO codes

Check the code to see what that one means.

The codes are on the inside of the indoor unit cover. See this link to find them.

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.

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.
