Why does A/C display a blinking Eo code?

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

Mitsubishi Mr Slim Inverter not blowing cold air. 2 solid, green indicator lights on. Fan barely blowing even on highest setting. What is the fix?

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.

I have a Mitsubishi Mr. Slim mounted in my wall. I let the filter get too dirty. It stopped and one green light was blinking on the unit. I cleaned it thoroughly. Started. Worked for about 60 seconds.

I got this free Pdf manual from reliable-store. com for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years

Black particles coming out of my Mitsubishi ductless air conditioner

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.

Why does my Mitsubishi ductless air conditioner drop black particles

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.

We have a ductless Mitsubishi split in our Florida trailer home which we will soon be leaving for seven months. Anything we should know about leaving it behind? We are not planning on leaving it running as it is our first year of using it and we aren’t sure of potential problems we might have while we are up north. Thanks for an advice

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.

14times blinking error on mitsubishi electric mr slim

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.

Is the remote for a Mitsubishi heat pump also a thermostat and does it matter where it is located in the room?

Put on an inside wall away from doors or open windows 5' above the floor and if you have an air vent close shut it

Mitsubishi inverter air conditioning set at 17 degrees actu al air temp 25 degree s what’s wrong ?

You cannot set it that low. It depends on your outside temp? Have you cleaned the filters and condenser coil? The lowest I recommend setting it at is 20. Any lower and you could freeze up the indoor coil. Once it thaws out you will have more water than the pump/drain can handle.

Mitsubishi Split system not cooling indoor and outdoor fans both run, however the Freon lines are ambient temperature, and I don't hear the compressor

This could be the compressor start and run capacitor. They are not that expensive but not everyone sells them without sending out a technician and then the bill starts at about 200. IF you are not used to working with something like this, it is better to call a tech.

Can the Mitsubishi Electric MSH-17DV be charged with R407C?

No Mitsubishi units are critically charged. Use only R22. They engineer the heck out of their units....they don't like other refrigerants in the system and won't warranty any problems with any other refrigerants
