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 works for a about a minute and then the light blinking begins and it shuts off? What would be the most likely problem?

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.

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.

Should have a dry contact on the board, cant remember what number (m4?), possibly loose wire or cut. Put a jumper and see what happens

If I was you I would pull the power disconnect to the condensing unit. You may also want to cover the condenser only to keep dogs or cats from urinating on the unit. If there is no possable way that will happen no need to cover it. When you come back in7 monts make sure the breaker is off to unit and wash condensing coil with high pressure from garden hose.

Most likely, there has been an operational fault that has triggered a "lock out". This happens when either a mechanical or electrical component has failed, misreading, or if the system has lost refrigerant. You can try to reset the system (both indoor and outdoor units). That might restart it, but a repairman should be called to pinpoint the issue that caused the fault. There is a diagnostic procedure that can help with the diagnosis, but it involves opening the outdoor unit to read the LED's on the control board.

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.
